Eye Allergies: Causes, Symptoms, and Treatment
If your eyes get itchy, red, and watery during certain seasons or around pets and dust, you may be dealing with allergic conjunctivitis.
What Are Eye Allergies?
Eye allergies, medically known as allergic conjunctivitis, occur when the eyes react to allergens like pollen, dust mites, pet dander, or mold. The immune system releases histamine and other chemicals in response, causing inflammation of the conjunctiva, the clear membrane covering the white of the eye and inner eyelids.
Common Triggers
- Seasonal pollen (grass, trees, weeds)
- Dust mites
- Pet dander
- Mold spores
- Cosmetics and contact lens solutions
- Air pollution and smoke
- Perfumes and certain medications
Symptoms
- Itching (often the most prominent symptom)
- Redness
- Watery discharge
- Swollen eyelids
- A burning sensation
- Sensitivity to light
Treatment and Management
- Avoid triggers: Identify and minimize exposure to known allergens when possible.
- Cold compresses: Help soothe itching and reduce swelling.
- Artificial tears: Help wash away allergens and dilute histamine in the tear film.
- Antihistamine eye drops: Provide fast relief from itching and redness.
- Mast cell stabilizer drops: Prevent the release of histamine when used consistently, often before allergy season begins.
- Oral antihistamines: Helpful for broader allergy symptoms, though they can sometimes dry out the eyes further.
Prevention Tips
- Keep windows closed during high-pollen seasons
- Wash hands and face after being outdoors
- Use air purifiers indoors
- Wash bedding regularly in hot water to reduce dust mites
- Avoid rubbing your eyes, which worsens irritation and can release more histamine
- Remove contact lenses during allergy flare-ups
When to See a Doctor
If symptoms are severe, persistent, or accompanied by pain, discharge that is thick or colored, or vision changes, see an ophthalmologist to rule out infection or other conditions that mimic allergies.
Frequently Asked Questions
Are eye allergies contagious?
No, allergic conjunctivitis is not contagious, unlike viral or bacterial conjunctivitis.
Can I wear contact lenses with eye allergies?
It's best to avoid contact lenses during active allergy flare-ups, as lenses can trap allergens against the eye and worsen irritation.
