Summer may be the season for holidays, pool days, and outdoor adventures, but it can also be surprisingly harsh on your eyes.
Intense sunlight, rising temperatures, dust, pollution, and increased screen exposure during indoor downtime can all contribute to irritation, dryness, and even long-term vision problems if ignored.
Eye specialists say that just like your skin, your eyes also need protection from ultraviolet (UV) radiation and environmental stress during the hotter months. Fortunately, a few simple precautions can significantly reduce the risk of discomfort and damage.
Dr Mandeep Singh Basu shares five important ways to keep your eyes healthy and protected this summer:
Wear Sunglasses That Block UV Rays
Not every pair of sunglasses offers proper protection. Experts recommend choosing sunglasses labelled UV400, which block 100 per cent of harmful UVA and UVB rays.
Extended exposure to UV radiation can increase the risk of cataracts, macular degeneration, and growths on the surface of the eye. Larger or wrap-around sunglasses provide better coverage by preventing sunlight from entering from the sides.
Never Stare Directly at the Sun
Looking directly at the sun can permanently damage the retina, a condition known as solar retinopathy. Since retinal damage occurs painlessly, many people may not realise harm is being done until vision problems develop later.
The risk remains even on cloudy days because ultraviolet radiation can still penetrate through clouds. Children are particularly vulnerable due to their more sensitive eyes and increased outdoor activity.
Keep Your Eyes Hydrated
Hot winds, air conditioning, fans, dehydration, and prolonged screen time can all dry out the eyes during summer. Common symptoms include redness, burning, itching, watering, or a gritty sensation.
Doctors advise drinking plenty of water throughout the day and using preservative-free lubricating eye drops when needed. Rubbing the eyes should be avoided, as it may worsen irritation and damage the eye surface.
Protect Your Eyes While Swimming
Swimming pools contain chlorine that can irritate the eyes and weaken the natural tear film. Beaches can also expose the eyes to saltwater, sand particles, and bacteria.
Wearing swimming goggles helps minimise irritation and reduces the risk of infections. Experts also warn against swimming with contact lenses, as they can trap harmful microorganisms and increase the chances of serious corneal infections.
Persistent redness or discomfort after swimming should be examined by an eye specialist instead of being treated with random over-the-counter drops.
Reduce Screen-Related Eye Strain
Spending long hours on phones, laptops, or televisions can strain the eyes, especially in hot weather when dryness is already common. Continuous screen exposure reduces blinking, making it harder for the eyes to stay naturally lubricated.
Eye experts recommend following the 20-20-20 rule — every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps relax eye muscles and reduce fatigue.
While summer activities are meant to be enjoyed, eye protection should not be neglected. UV-related damage builds gradually over time, and daily habits can make a major difference in preserving long-term vision and eye comfort.
