Red, itchy, watery eyes? You might be wondering whether allergies or a cold are to blame. While both conditions can affect your eyes, they have distinct causes, symptoms, and treatments. Understanding the difference can help you find the right relief and know when to seek professional care.
At Pacific Rims Optometry we are dedicated to helping you find the cause and treatments for eye conditions.
How Allergies and Colds Affect the Eyes
- Allergies: Eye allergies, also called allergic conjunctivitis, occur when allergens like pollen, dust, or pet hair trigger an immune response. The eyes become itchy, red, watery, and swollen due to histamine release. Symptoms are often seasonal or occur after exposure to allergens.
- Colds: Viral infections, like the common cold, can cause viral conjunctivitis. The eyes may feel irritated, appear red, and produce watery or mucus-like discharge. A cold also brings sneezing, congestion, and a sore throat, while allergies do not.
Symptoms of Eye Irritation from Allergies and Colds
To diagnose the cause of your eye irritation, it is important to look at the different symptoms that accompany allergies and colds.
Symptoms of Allergies
If your eye irritation is caused by allergic reactions, they are often paired with:
- Sneezing
- Nasal congestion
- Itchiness
With allergies, you typically will not experience any body aches or fever. Allergic symptoms might reoccur every time you encounter allergens and will persist as long as exposure continues.
Symptoms of Colds
When your eye irritation is caused by a common cold your symptoms might include:
- Sore throat
- Body aches
- Mild fever
- Congestion
Cold symptoms typically last 5-7 days as the virus runs its course.
Treating Eye Irritation Caused by Allergies and Colds
Both allergies and colds can be treated using over-the-counter medications, and additional treatment will only be required if symptoms persist.
- For allergies: Over-the-counter antihistamines, artificial tears, and avoiding allergens can help relieve eye irritation. Allergy eye drops or prescription medications may be necessary for severe cases.
- For colds: Since colds are viral, the best treatment is rest, hydration, and over-the-counter decongestants or pain relievers to manage symptoms. Lubricating eye drops can ease irritation.
When to Seek Professional Eye Care for Colds and Allergies
If your symptoms persist for more than 10 days (about 1 and a half weeks) or continue to worsen, it might be time to seek treatment from an eye care professional. Eye pain, light sensitivity, vision changes, and discharge may all be reasons for concern.
