As Ireland moves into brighter, warmer months, eye specialists are warning of a seasonal surge in eye-related problems. According to recent data from the Irish College of Ophthalmologists, eye irritation, infections and UV-related damage increase by up to 25% during spring and summer. Longer daylight hours, higher pollen counts and stronger ultraviolet (UV) rays all contribute to this rise.
Mireia Roca, Veonet Ireland ophthalmologist, explains that while many people take precautions for their skin in the sun, few realise how vulnerable their eyes are to seasonal damage. “The eyes are exposed to the same UV radiation that causes sunburn. Over time, this exposure can accelerate the development of cataracts and other degenerative eye conditions,” she says.
Increased cataract risk by prolonged UV Exposure
The Hidden Impact of Sunlight on Eye Health
UV radiation is a leading environmental factor in the early onset of cataracts, a clouding of the eye’s natural lens that can blur vision and, if untreated, lead to blindness. Studies show that prolonged UV exposure can increase cataract risk by up to 20%, particularly in individuals who spend long hours outdoors without adequate eye protection.
In addition to cataracts, sunlight can trigger photokeratitis (a painful sunburn of the cornea), pterygium (a growth on the white of the eye) and macular degeneration, a leading cause of vision loss in older adults.
Common Warm-Weather Eye Issues
Dry eyes: Warm winds and air conditioning can reduce tear film stability, leading to irritation and redness.
Allergic conjunctivitis: Pollen and dust levels rise in spring, causing itchy, watery eyes.
Infections: Swimming in untreated or chlorinated water can introduce bacteria, increasing the risk of conjunctivitis.
If you notice any of these symptoms, book a consultation with one of our consultant ophthalmologists:
How to Protect Eyes in the Warmer Months
- Wear UV-blocking sunglasses: Choose lenses that block 100% of UVA and UVB rays. Wraparound styles offer the best protection.
- Add a wide-brimmed hat: This reduces direct sunlight exposure by up to 50%.
- Avoid peak sun hours: UV intensity is highest between 11 am and 3 pm.
- Stay hydrated: Adequate water intake supports tear production and eye comfort.
- Use lubricating eye drops: These help relieve dryness caused by wind or air conditioning.
- Avoid rubbing eyes: This can worsen irritation and spread allergens or bacteria.
- Schedule regular eye checks with your optometrist: Early detection of UV-related changes can prevent long-term damage.
Treating Sun-Related Eye Conditions
If symptoms such as blurred vision, persistent redness or light sensitivity occur, prompt assessment by an ophthalmologist is essential. Treatments may include prescription eye drops, anti-inflammatory medication or, in advanced cases, cataract surgery.
