The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you. 

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts. 

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes. 

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens. 

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you. 

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Contact Lens Eye Exam Near You

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable. 

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.

5 Facts About Scleral Lenses

happy teenagers 640Scleral contact lenses are large-diameter gas permeable contact lenses that vault over the cornea and rest on the “white” of the eye (the sclera). In doing so, the lenses form a dome over the irregular cornea that provides clear and comfortable vision for individuals with keratoconus, dry eye and other ocular surface conditions.

Here are 5 facts about scleral lenses and why they are a great choice for many patients.

1- They work when nothing else will.

Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition or complications following surgery, can at times develop vision problems that cannot be corrected using glasses or soft contact lenses. In such cases, scleral lenses provide a more comfortable, stable, secure fit, and improved vision.

For those with keratoconus, scleral contact lenses provide advanced care that resolves visual distortions and creates clear vision while providing a comfortable wearing experience.

In addition to helping those with keratoconus, scleral lenses are also recommended for those with an astigmatism, particularly for high astigmatism that other contacts cannot comfortably correct.

2- Scleral contacts provide relief for those who suffer from dry eye.

Unlike traditional contact lenses, scleral lenses minimize eye irritation. Since they vault over the dry, irritated cornea and sit on the sclera, they offer comfort and clear vision. Sclerals leave a space between the lens and the cornea containing a liquid reservoir of artificial tears that provides a protective cushion that soothes the eye.

This is crucial, because even blinking can irritate the eye or injure the cornea due to the mechanical friction of the eyelids on the cornea. Scleral lenses can act as a shield between a patient’s eyes and their eyelids, protecting the eyes from further irritation or damage.

3- Sclerals are long lasting lenses.

Constructed from high quality, durable materials, these rigid gas permeable contacts typically last 1-3 years. Therefore, while the initial cost of scleral lenses is higher than standard contacts, you’ll benefit from maximum value for your money.

While scleral lenses are long lasting, it is important to book follow up visits with your eye doctor to determine when it’s time to replace them with a new pair, so as not to harm your cornea.

4- Scleral contacts are worth the cost

People assume that because sclerals must be fitted and customized to fit each individual eye, they are exorbitantly expensive. In fact, the lenses are often covered by insurance and certain vision and health savings plans.

These lenses provide enough of an improvement over regular lenses — in both comfort and vision — to justify the investment.

5- Scleral lenses are very comfortable.

Some people mistakenly assume that rigid contacts aren’t comfortable. In reality, scleral contact lenses are very comfortable because they don’t touch the cornea and lubricate the eyes.

If you have irregular corneas, dry eye or hard-to-fit eyes, scleral lenses may be right for you. Find out more about scleral lenses by scheduling an eye exam at The Scleral Lens and Keratoconus Center at Pacific Rims Optometry today!

Are Face Masks Causing Dry Eye Symptoms?

woman wearing a mask 640Face masks and social distancing have become the first line of defense in COVID-19 prevention.

While these protective measures are essential to combating the virus’ spread, eye doctors are seeing an increase in dry eye cases among people who wear masks. If you are seeking relief, contact us.

What is Mask-Associated Dry Eye (MADE)?

Mask-associated dry eye (MADE) was first described by an ophthalmologist in May 2020 based on the higher rate of dry eye he was seeing in his practice among patients who wore masks. Patients with existing dry eye reported worsening symptoms when wearing a mask.

When a face mask doesn’t fit securely, it can push air from the nose and mouth upward, onto the eyes, causing the tear film — the liquid layer that coats the eyes’ surface — to evaporate more quickly. This leads to MADE.

Dry eye leaves the eyes feeling sore, gritty, dry and irritated. Left untreated, dry eye can cause damage to the cornea.

There are many causes of dry eye, including eye and health conditions, age, gender and certain medications. Insufficient blinking when looking at a digital device or book, poor indoor air quality and pollution can all play a role. Situations that increase how quickly the tear film evaporates can quickly and significantly dry the eye’s surface, leading to more pronounced symptoms.

What Causes Dry Eye When Wearing a Mask?

Wearing a face mask significantly reduces the spread of air when breathing out from the mouth and nose. Instead of moving out, the air moves upwards towards the eyes’ surface. This forces a stream of air over the surface of the eye, causing the tears to evaporate more quickly.

This is the same reason that eyeglasses fog up when wearing a mask.

When masks are worn for long periods of time, this repeated evaporation may lead to dry spots on the eyes’ surface.

 

How to Prevent or Alleviate MADE?

Here are some simple measures to help reduce dry eye while wearing a mask:

  1. Ensure your mask fits well, and consider taping the top edge to prevent air from rising from your mouth toward your eyes.
  2. Limit your time in air-conditioned or heated environments when possible. Also, take regular breaks from digital devices.
  3. Consult your eye doctor, who will examine your eyes and prescribe the best treatment.

Having to wear a face mask to prevent COVID-19’s spread may cause dry eye, but relief is available. Contact The Dry Eye Center at Pacific Rims Optometry if you are experiencing dry eye symptoms. We will determine the underlying cause of your dry eye and offer you the best solution so you can get back to having comfortable eyes and vision.

8 Ways Your Eyes Change With Age

Our eyes and vision change with age. Your eye doctor can monitor these changes — some of which are a natural part of the aging process — and identify any eye conditions or diseases early enough to treat them and prevent vision loss. Read on to learn more about the different types of eye changes one may encounter with age.

Age-Related Eye Conditions and Diseases

Cataracts

If your vision is starting to get blurry, you may be developing cataracts. There are a few types of cataracts, but the one usually caused by aging is known as a “nuclear cataract”. At first, it may lead to increased nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and clouds your vision. As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color, and left untreated, it can eventually lead to blindness. Luckily, cataract surgery, where the cloudy lens is replaced with a clear lens, is an extremely safe and effective treatment option. 

Blepharoptosis

Blepharoptosis or ptosis is a drooping of the upper eyelid that may affect one or both eyes. The eyelid may droop only slightly or may droop enough to cover the pupil and block vision. It occurs when there is a weakness of the eye’s levator muscle that lifts the eyelid. This condition is usually caused by aging, eye surgery, or disease affecting the muscle or its nerve. Fortunately, blepharoptosis can be corrected with surgery.

Vitreous detachment

This occurs when the gel-like vitreous fluid inside the eye begins to liquefy and pull away from the retina, causing “spots and floaters” and, sometimes, flashes of light. This occurrence is usually harmless, but floaters and flashes of light can also signal the beginning of a detached retina — a serious problem that can cause blindness, and requires immediate treatment. If you experience sudden or worsening flashes and increased floaters, see Dr. Selena Chan immediately to determine the cause.

Other Age-Related Changes

In addition to the above eye conditions and diseases, the structure of our eyes and vision change as we get older. 

Presbyopia

Why do people in their 40s and 50s have more difficulty focusing on near objects like books and phone screens? The lens inside the eye begins to lose its ability to change shape and bring near objects into focus, a process is called presbyopia. Over time, presbyopia, also known as age-related farsightedness, will become more pronounced and you will eventually need reading glasses to see clearly. You may need multiple prescriptions – one prescription to enable you to see up close, one for intermediate distance, and one for distance vision. In that case, people often get bifocals, multifocals or PALs, and they can be combined with contact lenses as well.

Reduced pupil size

As we age, our reaction to light and the muscles that control our pupil size lose some strength. This causes the pupil to become smaller and less responsive to changes in ambient lighting. The result? It becomes harder to clearly see objects, such as a menu, in a low-light setting like a restaurant.  

Dry eye

Our tear glands produce fewer tears and the tears they produce have less moisturizing oils. Your eye doctor can determine whether your dry eye is age-related or due to another condition, and will recommend the right over-the-counter or prescription eye drops, or other effective and lasting treatments, to alleviate the dryness and restore comfort.

Loss of peripheral vision

Aging causes a 1-3 degree loss of peripheral vision per decade of life. In fact, one may reach a peripheral visual field loss of 20-30 degrees by the time they reach their 70s and 80s. While peripheral vision loss is a normal part of aging, it can also indicate the presence of a serious eye disease, like glaucoma. The best way to ascertain the cause is by getting an eye exam. 

Decreased color vision

The cells in the retina responsible for normal color vision tend to decline as we age, causing colors to become less bright and the contrast between different colors to be less noticeable. Though a normal part of aging, faded colors can at times signal a more serious ocular problem. 

Beyond the normal changes that come with age, the risk of developing a serious eye disease, such as age related macular degeneration and glaucoma, increases. Routine eye exams are essential to keeping your eyes healthy. Your eye doctor can determine whether your symptoms are caused by an eye problem or are a normal byproduct of aging. 

If you or a loved one suffers from impaired vision, we can help. To find out more and to schedule your annual eye doctor’s appointment, contact Pacific Rims Optometry in San Francisco today. 

5 Ways to Get Your Kids Outdoors This Winter and Save Their Vision

kids playing in the snow 640

Just because the weather is cooling down, it doesn’t mean that your kids should be kept indoors all winter long. In fact, there are many reasons to have them spend time outdoors, not least of which is to protect your child’s vision. Studies show that children who spend time playing outdoors in the sunshine experience less myopia progression than those who stay indoors. Moreover, encouraging more outdoor playtime is important for promoting overall health and wellbeing in your kids.

Below we’ll explore some fun outdoor activity ideas to try with your kids and discuss why spending time outdoors may slow a child’s myopia progression or even postpone its onset.

5 Outdoor Activities to Do With Your Kids This Winter

1. Snow Play

If you live in a snowy region, bundle up your kids in warm layers and have them:

  • Build a snowman
  • Enjoy a snowball fight
  • Paint the snow with some food coloring or watercolors
  • Make a snow maze
  • Build an igloo
  • Build snow castles (the same way you would sand castles)
  • Make snow angels
  • Collect snowflakes during a snow flurry and study their beautiful shapes

2. Blow Ice Bubbles

Kids love playing with and popping bubbles. If temperatures are low enough, they might freeze in mid air! They’ll get a kick out of watching them freeze and possibly catching or popping them.

To make your own bubble solution, mix 1 part water with 4 parts dish soap and a few drops of light corn syrup. It’s best to try this activity when winds are calm, as harsh breezes can cause the bubbles to pop before they freeze.

Once the bubbles have landed on a surface and are completely frozen, they are beautiful to photograph — which can be part 2 of this activity.

3. Go Sledding

Sledding is a classic winter activity that your child will love. To go sledding, all you need is snow, a sled, and a hill! Easy enough.

But before you hit the slopes (or hills), be sure to follow these safety guidelines:

  • Choose a sled that can be steered and can brake
  • Wear a helmet
  • Dress warmly, but be careful as the scarf can get caught under the sled
  • Children 5 years old and under should sled with an adult

4. Go on a Winter Scavenger Hunt

A winter scavenger hunt is a wonderful way to explore nature with all of your senses. Before you head out, make a list of things to see, smell, listen for, and feel. Ask your child to check each item off the list.

For example, your list can include listening for the sounds of birds chirping, footsteps crunching in the leaves, or water babbling in a nearby stream. On the list of things to look for, you can include different types of trees, animals, animal tracks, cloud shapes, birds’ nests, and more. Take your camera along and let your child take pictures of what they find.

You can also leave an empty space on the list for your child to fill as they explore new things on their own.

5. Decorate a Tree with Edible Ornaments For Animals

This activity is an unconventional twist on building a bird-feeder and perfect for those who live near a forest. The idea is to make edible ornaments and hang them on a tree (or potted plant in your garden) for wildlife to feed on during the winter.

Your ornaments can be made using various seeds, peanut butter, dried fruit, and popcorn. It’s best to use biodegradable materials to hang your ornaments, and don’t use fishing lines, as birds can get caught in it.

What’s the Connection Between Time Outdoors and Myopia?

There is increasing evidence that children who spend extra time daily playing outdoors have a reduced risk of developing myopia; and if they already have myopia, time spent outdoors could slow down the worsening of this condition, also known as myopia progression.

These findings are significant, as having myopia significantly increases a child’s risk of developing sight-threatening eye diseases later in life. Moderate to high levels of myopia make a child more susceptible to developing cataracts, retinal detachment, macular degeneration, and glaucoma later in life.

At Pacific Rims Optometry, our mission is to battle childhood myopia by providing myopia management to nearsighted children. Our myopia management treatments can effectively slow down your child’s myopia progression and reduce their future risk of eye disease.

If your child has myopia, or if you need your first consultation, contact us today to schedule a myopia eye exam.

Wishing you and all of our patients a healthy and enjoyable winter season!

Protect Your Eyes From Vision Loss: Diabetes Awareness Month

What Is Diabetic Retinopathy?

Diabetic Retinopathy (DR) is one of the most prevalent eye diseases affecting the working age population. It is thought to be caused by high blood sugar levels which, over time, damage the tiny blood vessels of the retina at the back of the eye, making them swell and leak. Left untreated, DR can lead to vision loss and eventually blindness.

Since diabetic eye disease is typically painless and shows no symptoms until its advanced stages, it’s critical to get your annual eye evaluation, as an optometrist can detect the developing signs early enough to prevent vision loss.

Symptoms of Diabetic Retinopathy 

Diabetics may not realize they have diabetic retinopathy, because it develops silently. As the condition worsens, it may cause: 

  • Blurred vision
  • Poor night vision
  • Colors to appear faded or washed out
  • An increased presence of floaters
  • Vision loss
  • Blank or dark areas in your field of vision

Diabetic retinopathy symptoms usually affect both eyes.

Risk Factors

If you are diabetic, caring for your eyes by undergoing routine eye exams and taking care of your body by controlling blood sugar levels are critical to preventing vision loss. There are several risk factors associated with diabetic eye complications, including: 

  • Poor blood sugar control
  • Smoking
  • High cholesterol 
  • High blood pressure
  • Pregnancy
  • Excess weight/obesity

Are There Any Treatments for Diabetic Retinopathy?

Today’s treatment options may improve your vision, even if you feel your eyesight has begun to deteriorate. Medications can be injected to reduce swelling, and laser surgery can be used to shrink and seal off swollen and leaking blood vessels — preserving and, in many cases, even improving vision. 

While certain treatments may work, frequent monitoring of your eyes coupled with managing your blood sugar levels can go a long way toward preventing or reducing diabetic retinopathy complications. 

If You Have Diabetes, Make Sure to: 

  • Control blood sugar and blood pressure to prevent long-term damage to the fine blood vessels within the retina.  
  • Keep a healthy lifestyle routine, especially during stressful times such as the COVID-19 pandemic. (Plus, while diabetics are in the high-risk category, your chances of developing serious COVID-19 related complications is lower if your diabetes is under control.)
  • Maintain a steady diet and exercise regimen to help the body and mind feel better. 
  • Quit smoking, if applicable; you can reach out to a medical professional for guidance.
  • Get yearly diabetic eye exams.

Preventing and managing diabetic retinopathy require a multi-disciplinary approach involving your eye doctor and other medical professionals. Your eye doctor will perform a comprehensive eye exam to determine whether you have diabetic retinopathy, assess its severity, and discuss preventative strategies as well as the latest treatment options. 

Contact Pacific Rims Optometry at 833-453-0313 to schedule your diabetic eye exam today, and to learn more about what you can do to protect your vision and general health.

New To Contact Lenses? Here Are Our Top 5 Tips!

For an estimated 56 million North Americans, contact lenses are the preferred form of vision correction. So if you’ve just started wearing contact lenses — you’re in good company.

Advice About Contact Lenses from San Francisco Eye Doctor: Dr. Selena Chan

Here are 5 tips to quickly help you adjust to wearing and caring for your new lenses so you can enjoy the many benefits they offer.

  1. Learn How to Tell if Your Contact Lens Is Inside Out

This is a common mistake many beginners make when inserting soft contacts. Place the lens on  your index fingertip and look carefully at its shape. The edge of the lens should be pointing upwards, like the rim of a teacup. If the edge is flared outward like a blooming flower, the lens is inside out.

Some contact lenses have tiny laser markings of numbers or letters. If the numbers/letters read correctly when you hold the lens on your fingertip, they are properly oriented and the lens is ready to be inserted.

  1. Never Use a Substitute for Contact Lens Solution

Your eye doctor will recommend the appropriate contact lens solution to suit your eyes and lenses. Some people have sensitivities and not all lens solutions are the same. 

Even if you run out of contact lens solution, don’t be tempted to rinse your lenses with water, and never use saliva to moisten or clean them.

Using substances other than the recommended contact lens solution to rinse or rewet your contacts can introduce harmful microbes to the eye and cause a serious infection. That’s why it’s best to remove your contacts before showering, swimming, or any other time they might get wet.

  1. If Your Contact Lenses Feel Uncomfortable, Take Them Out!

Some newcomers mistakenly think that if their contacts feel uncomfortable or gritty, they simply need to “get used to them.” Contact lenses are supposed to be comfortable, so if you are experiencing discomfort there may be something wrong.

With clean fingers, remove your contacts and rinse them, inside and out, with the solution or rewetting drops as recommended by your eye doctor. Dust or dirt could have gotten stuck between the lens and your eye, causing irritation. Flushing the lenses with contact lens solution will help remove the irritant.

If your eyes still feel irritated, don’t place the contact lenses back in your eyes. Instead, wait until they are no longer red or irritated, and try inserting them again. If the problem persists, contact your eye doctor.

  1. Wear Contact Lens-Friendly Makeup

Wearing makeup around the eyes can be a source of irritation and infection whether you wear contact lenses or not. Here’s what we recommend when it comes to eye makeup and contact lenses:

  • Choose hypoallergenic makeup.
  • If using a cream-based product around your eyes, choose a water-based formula instead of an oil-based one. 
  • Keep your eye closed during application to avoid makeup particles entering your eye. 
  • Don’t apply eyeliner or eyeshadow to the inner rims of your eyelids.
  • Replace eye makeup at least once every 3 months to minimize the growth and spread of bacteria.
  • Never share eye makeup with friends or family.
  • Remove your contact lenses before removing your makeup.
  1. Stick to the Hygiene Guidelines

We can’t emphasize this enough — always thoroughly wash and dry your hands before handling your contact lenses.

Try to avoid washing your hands with oily or heavily scented hand soaps, as they tend to cling to the surface of the lens and could irritate the eye. Additionally, if you touch moisturizers or lotions before handling your contact lenses you run the risk of some residual product adhering to the lens and clouding your vision.

After washing your hands, dry them using a lint-free towel. It’s harder to grasp contact lenses with wet hands, and — as mentioned above — lenses shouldn’t come into contact with tap water.

Bonus Tip: Get an Eye Exam

While all this advice can be very helpful, it doesn’t replace an in-person exam with your eye doctor.  Your eye doctor will advise you when to return for your next contact lens consultation. Following this schedule is the best way to ensure you can enjoy the freedom of contact lens wear.

If you are new to contact lenses (or not!) and have any questions or concerns about your eyes or vision, call 833-453-0313. Pacific Rims Optometry will be happy to schedule you for a contact lens exam and fitting.

With the help of Dr. Selena Chan, you’ll be an expert in contact lens wear and care in no time!

FDA- Approved MiSight Contact Lenses Do Wonders in Reducing Myopia Progression!

If there is one thing that eye health professionals agree on, it’s that myopia is an eye disease of
growing proportions.

Having myopia as a child significantly increases the risk of developing sight-threatening conditions like macular degeneration, glaucoma, and retinal detachment later in life. Even children with low levels of myopia have a greater risk of glaucoma and retinal detachment compared to their non-myopic counterparts.

The good news is that slowing down the progression of myopia can drastically lower the risks of
developing eye disease later in life. Innovative products like MiSight 1-day contact lenses help
ensure a healthier future for myopic children.

As part of the Treehouse Eyes network, we are proud to be one of the first practices in the country to be certified to fit MiSight 1-day contact lenses for myopia treatment and be part of the Brilliant Futures Myopia Management Program.

CooperVision, which manufactures MiSight 1-day lenses, calls Brilliant Futures “the new standard of care” for children with myopia. “It provides inclusive practice, child and parent support to create the optimal environment for compliance, satisfaction, clinical outcomes, and long-term loyalty, all via a comprehensive management program featuring MiSight 1-day daily disposable contact lenses.”

What are MiSight 1-Day Contact Lenses?

MiSight 1-day contact lenses are soft lenses that are worn daily and disposed of after each use.
A fresh pair of contacts are placed into the eyes every morning to provide the child with a crisp and clear vision while also slowing the eye’s elongation — the source of progressive myopia.

These contacts are safe and easy for children to use since they require almost no maintenance.

MiSight 1-Day Contact Lenses: A Popular Choice

CooperVision recently partnered with Sarah Michelle Gellar, a well-known American actress, entrepreneur and producer, to help spread awareness about the importance of myopia management and annual eye exams for myopic children.

The need for myopia management hit home for Gellar, who is myopic herself and has a child with myopia. “My husband and I are both nearsighted and our myopia has continued to worsen over time. We want our kids to have a chance for better vision and lower their risk for future eye health issues” explains Gellar.

While regular eyeglasses or contacts help children see a whiteboard or tennis ball, “MiSight 1- day lenses offer children the benefits of clear vision while slowing myopia progression during their growing years. That is why I am thrilled to be partnering with CooperVision on this campaign,” Gellar says.

Moreover, many parents are pleased to learn that MiSight 1-day contact lenses are FDA approved. In November 2019, the lenses received FDA approval to slow myopia progression in children who are 8-12 years old at the time of their first fitting — making MiSight 1-day contact lenses the only FDA approved soft contact lenses for myopia management!

We Are Proud to Be Part of the Myopia Management Movement

In addition to MiSight, our highly trained and experienced doctors can offer other treatment options to manage childhood myopia, including specialized overnight-wear contact lenses and prescription eye drops.

Keratoconus and Coronavirus

Middle Aged Couple Multifocal ContactsKeratoconus refers to the thinning and elongation of the cornea, the transparent layers over the eye, into a cone-like shape. That results in blurred vision. Other symptoms include vision difficulties at night and objects appearing to have a glare or halos around them.

If you have keratoconus, several options are available.

For a mild or moderate condition, eyeglasses or soft contact lenses will help. Some people do better with rigid gas permeable (hard) contact lenses. If contact lenses hurt your cornea, scleral lenses are recommended. They vault over the cornea and rest on the sclera, the white part of the eye. For more severe cases of keratoconus, laser treatment and corneal transplants are recommended.

Hygiene for Scleral-Lens Wearers in the Coronavirus Era

As always, hygiene is paramount when you handle and wear scleral lenses, as it is with soft and hard lenses. This means thoroughly washing your hands before touching the lenses, and cleaning and rinsing the lenses with recommended solutions.

Wearing sclerals and other contact lenses during the coronavirus pandemic remains as safe as ever, but it’s even more important now to observe hygiene guidelines. In fact, you can take extra precautions to lower the risk of inadvertently transmitting the coronavirus to your eyes, from where it can enter your body.

Consider taking these additional preventative steps:

  • Use disinfectant wipes to clean the counters and other surfaces where you place the scleral-lens cases and solutions. This includes disinfecting the cases and containers of solutions before using.
  • Wash your hands before touching your eyes or removing your lenses.
  • Don’t touch the area on/near your eye and then someone else’s, or vice versa.
  • Avoid rubbing your eyes to prevent keratoconus from developing or worsening, while also reducing the risk of getting infected by coronavirus.

If you have keratoconus and are concerned about maintaining your optical health while reducing the risk of coronavirus, contact us.

How to Get Rid of Eyelash Mites

How to Get Rid of Eyelash Mites 640What if we told you that there are tiny critters living on your face? Would you believe it?

The truth is that just about every person on earth has Demodex mites living in their facial pores.

But before you run to the bathroom sink and start scrubbing your cheeks, read on to learn what these microscopic mites are, and how they can affect your eyes.

What are Demodex Mites?

Demodex mites are tiny 8-legged arachnids that make their home in the pores and hair follicles of your face. Fortunately, they’re too small to see with the naked eye, measuring only 0.4 mm long.

There are 2 types of Demodex mites: Demodex folliculorum and Demodex brevis. Both types can be found all over the face, but Demodex folliculorum mites tend to concentrate around the eyelash area.

Demodex mites live inside hair follicles, where they feed on dead skin cells and oily sebum that is secreted onto the hair shaft. That’s why they’re found in higher numbers around greasier areas of the body, like the eyes and nose.

The mites come out of the hair follicle at night to mate and then return in the morning. For this reason, symptoms of a Demodex infestation may be worse in the morning.

Demodex mites can be transferred from one host to another through facial skin or hair contact. They can also be introduced to a new host through shared makeup and cosmetics.

Having a small amount of Demodex mites seems to be harmless, but an overgrowth of mites — called “demodicosis” — can cause a host of symptoms affecting the eyes and other areas of the face. A Demodex infestation can also exacerbate pre-existing skin conditions like rosacea and acne.

How Can Demodex Mites Affect Your Eyes?

Too many Demodex mites can cause uncomfortable symptoms that may include:

  • Itchy or burning eyes, especially in the morning
  • Swollen eyelids
  • Crusty eyes
  • Red, irritated eyes
  • Watery eyes
  • Blurred or decreased vision
  • Falling eyelashes
  • Infected eyes

If you experience a yellowish discharge on your eyelashes mainly in the mornings, this could be a sign of a Demodex mite infestation.

Severe cases of demodicosis can lead to blepharitis — an inflammation of the eyelids. Blepharitis often leads to an inflammation of the cornea called keratitis, a serious condition that can lead to blindness if left untreated.

Risk Factors For Demodicosis

You’re more likely to have a Demodex mite outbreak if you:

  • Have oily skin
  • Wear makeup
  • Sleep overnight without properly removing makeup
  • Have poor personal hygiene

Some pre-existing conditions that increase the possibility of a Demodex outbreak include:

  • A weakened immune system
  • Alopecia
  • Inflammatory acne
  • Dermatitis

Your Dry Eye Optometrist Can Help

The good news is that Dr. Selena Chan can provide safe and effective treatment for your demodicosis.

Because Demodex mites are so small, they’re impossible to diagnose on your own. Only a comprehensive eye exam can determine the source of your symptoms.

Treatment for a Demodex mite infestation typically involves a medicated ointment that can prevent the mites from reproducing. In severe cases, oral medication may be prescribed. Your eye doctor may also manually clean the margins of your eyelids or recommend over-the-counter products that can help soothe irritation and promote healing.

If you suspect you have demodicosis or experience any of the symptoms listed above, contact The Dry Eye Center at Pacific Rims Optometry to schedule an eye exam.
