Spring and summer bring longer days, warmer weather, and, for millions, hay fever.

While most people reach for antihistamines to manage sneezing and a runny nose, the eyes are often the most uncomfortable battleground. Itchy, red, watery eyes can make the warmer months genuinely difficult, but with the right care, you can protect your vision and enjoy the season.

Why Does Hay Fever Affect Your Eyes?

When pollen enters the air, your immune system can identify it as a threat and release histamine in response. In the eyes, this triggers what is known as allergic conjunctivitis: inflammation of the clear membrane that lines the eyelid and covers the white of the eye. The result is redness, swelling, itching, and excessive tearing. For contact lens wearers, the discomfort is often amplified, as pollen particles can become trapped beneath lenses and intensify irritation.

Practical Steps to Reduce Eye Irritation

The simplest way to protect your eyes during hay fever season is to reduce your exposure to pollen wherever possible. Keep windows closed on high-pollen days, particularly in the morning when counts tend to peak. Wearing wraparound sunglasses when outdoors creates a physical barrier between your eyes and airborne pollen, and has the added benefit of blocking UV rays.

After spending time outside, washing your face and hands promptly helps remove pollen before it has a chance to irritate your eyes further. Avoid rubbing your eyes, even when the urge is overwhelming. Rubbing releases more histamine and worsens inflammation, often turning a mild irritation into a prolonged flare-up.

Over-the-Counter and Prescription Options

Antihistamine eye drops can provide rapid relief for allergic conjunctivitis and are available without a prescription. Sodium cromoglicate drops work by stabilising the cells that release histamine, and are particularly effective when used before symptoms begin rather than after. Preservative-free artificial tears are a gentle option for flushing pollen from the eye surface and soothing dryness.

For persistent or severe symptoms, an optometrist can prescribe stronger drops or recommend a more tailored treatment plan. It is worth noting that oral antihistamines, while helpful for general hay fever symptoms, can sometimes cause dryness in the eyes, so speak to a professional if you notice your eyes feeling more uncomfortable after starting a new medication.

Advice for Contact Lens Wearers

If you wear contact lenses, hay fever season may be a good time to switch to daily disposables. Because they are replaced every day, there is less opportunity for allergens to accumulate on the lens surface. Alternatively, wearing glasses on high-pollen days gives your eyes a much-needed break.

When to See an Optometrist

If your symptoms are severe, persistent, or accompanied by significant swelling, blurred vision, or discharge, book an appointment rather than managing things alone. These can occasionally indicate a more serious condition that requires prompt attention. Seasonal allergies do not have to mean months of sore, streaming eyes.

With a few adjustments and support, your eyes can stay comfortable all season long.
