As Allergy Awareness Week (20th – 26th April) approaches, it's important to highlight one of the most common—yet often overlooked—symptoms of allergies: their impact on your eyes. With over a quarter of Brits affected by hayfever, and cases continuing to rise, many people are unknowingly mistaking allergy symptoms for screen-related eye strain. If your eyes feel irritated, watery or tired, it may not just be screen time—it could be allergies.
Why Allergies Are Often Mistaken for Eye Strain
Many people associate sore or tired eyes with long hours in front of screens. While digital eye strain is common, allergies are an increasingly overlooked cause—particularly as more people develop them later in life.
Dr Stephen Hannan, Clinical Services Director at Optical Express, explains:
"When the eyes are exposed to allergens such as pollen, dust or pet dander, the body releases histamines as part of its immune response. This leads to inflammation, redness, itching and watering. The difficulty is that allergy symptoms and screen-related eye strain often overlap. Reduced blinking during screen use disrupts the tear film, increasing dryness and irritation—this can make allergy symptoms feel worse and harder to identify."
Understanding Allergic Conjunctivitis
Allergic conjunctivitis occurs when allergens come into contact with the surface of the eye, triggering an immune response.
This leads to:
- Dilated blood vessels (redness)
- Increased tear production (watering)
- Itching and swelling
Because your eyes are directly exposed to the environment, they are particularly vulnerable to airborne allergens.
Common Triggers That Affect Your Eyes
Pollen (Hay Fever)
The most common trigger. Tree pollen peaks in spring, grass in summer, and weed pollen later in the year. Eye symptoms are often more noticeable than nasal symptoms.
Dust mites
A year-round trigger, often worse in the morning or during colder months when indoor heating increases exposure.
Pet dander
Proteins from animal skin, saliva and fur can trigger persistent symptoms—even in environments without pets.
Mould and cosmetics
Damp environments and certain skincare or makeup products can also cause irritation, particularly around the eyelids.
Signs Your Symptoms Are Allergy-Related
Key symptoms include:
- Intense itching (a key differentiator from other conditions)
- Redness in both eyes
- Excessive watering with clear discharge
- Swollen eyelids
- Burning or gritty sensation
- Light sensitivity
- Temporary blurred vision
Allergies vs Eye Strain: How to Tell the Difference
- Allergies: Itching, both eyes affected, linked to environment or season
- Eye strain: Dryness, fatigue, worsens with screen use
- Infections: Thick discharge, often one eye first
If itching is your main symptom, allergies are the most likely cause.
How to Manage Eye Allergy Symptoms
1. Use lubricating eye drops
Artificial tears help wash away allergens and restore moisture—especially important if screen use is worsening dryness.
2. Use targeted anti-allergy treatments
Antihistamine eye drops, such as Olopatadine, can provide fast and effective relief from itching, redness and swelling.
Other options include:
- Mast cell stabilisers (for prevention)
- Oral antihistamines (for broader symptom control)
As some treatments can contribute to dryness, combining them with lubricating drops is often beneficial.
3. Avoid contact lenses during flare-ups
Contact lenses can trap allergens against the eye, prolonging irritation. Switching to glasses temporarily allows the surface of the eye to recover. Wraparound sunglasses can also help reduce exposure to pollen outdoors.
4. Reduce allergen exposure
- Keep windows closed during high pollen periods
- Shower after being outdoors
- Use anti-allergy bedding
- Apply cold compresses (instead of rubbing your eyes)
Special Advice for Contact Lens Wearers
Contact lenses can intensify allergy symptoms by trapping allergens on the eye's surface.
If you suffer from allergies:
- Reduce wear time during flare-ups
- Consider daily disposable lenses
- Always keep glasses as a backup
For some patients, vision correction procedures such as laser eye surgery can remove the need for contact lenses altogether—helping improve comfort during allergy season.
When to Seek Professional Advice
You should book an eye examination if:
- Symptoms persist despite treatment
- Your vision is affected
- Only one eye is involved
- You experience pain or thick discharge
An optometrist can confirm whether your symptoms are allergy-related and recommend the most effective treatment.
