New Delhi: Summer vacation is here, and children across India are spending more time outdoors playing, swimming, and enjoying the long sunny days. However,
this season also brings significant risks to their developing vision. Harmful ultraviolet (UV) rays are at their strongest during summer, and children’s eyes are particularly vulnerable because their lenses allow up to 70 per cent more UV radiation to reach the retina compared to adults. From excessive screen time indoors while escaping the heat to chlorine exposure in swimming pools and allergens like pollen and dust causing eye allergies, summer presents multiple threats to children’s eye health that many parents overlook completely.
The good news is that pediatric ophthalmologists and eye care experts have identified five simple, practical, and doctor-backed strategies that parents can implement immediately to safeguard their children’s vision throughout the summer months. These expert-recommended tips cover everything from choosing the right sunglasses to managing screen time safely, preventing swimming pool infections, maintaining proper eye hygiene, and promoting a nutrient-rich diet for eye health.
How to protect children eyesight from UV rays
1. Shield their eyes from harmful UV Rays with quality sunglasses
Protecting your child’s eyes from UV radiation is the most critical step in summer eye care. Doctors recommend that children wear sunglasses offering 100 per cent UVA and UVB protection (UV400) whenever they’re outdoors, even on cloudy days. Look for sunglasses with the CE mark indicating they meet safety standards, and choose wraparound designs or larger frames that cover more area around the eyes for comprehensive protection. Children’s eyes are most susceptible to UV damage, and up to 80% of a person’s lifetime UV exposure occurs before age 18, making early protection essential for preventing future eye conditions like cataracts and retinal damage.
2. Follow 20-20-20 rule to prevent digital eye strain
With school out, children naturally spend more time indoors obsessed with electronic gadgets like smartphones, tablets, computers, and televisions. This increased screen time can cause digital eye strain, dry eyes, and in some cases even squints and accommodative issues if not managed properly. Doctors strongly recommend the 20-20-20 rule: every 20 minutes of screen time, take a 20-second break to look at something 20 feet away.
For young children aged 5–12, doctors recommend no more than 1 to 1.5 hours of recreational screen time per day outside of schoolwork. Set a timer or use screen reminder apps to gently nudge your child to take breaks, and encourage frequent blinking to maintain tear film stability.
3. Use protective swimming goggles and maintain pool safety
Swimming is a popular summer activity, but pool chlorine, sunscreen residue, and sun exposure create a “triple threat” that can cause eye irritation, redness, and even infections. Children should wear protective swimming goggles while swimming to prevent contact with chlorinated water, which can cause dry eyes and keratitis. After swimming, gently rinse your child’s eyes with clean water to remove any chemicals that may cause discomfort.
If your child wears contact lenses, never allow them to swim with contacts in – whether in a pool, river, pond, lake, or ocean. Contact lenses can trap chemicals and harmful organisms (bacteria, fungi, viruses), leading to dangerous infections.
4. Practice proper eye hygiene and never rub eyes with unclean hands
Summer brings a surge in allergic children due to increased pollen and dust levels in the air. Children should avoid rubbing their eyes with unclean hands as this can scratch the cornea (the outer layer of the eye) and introduce infections. If sand, dust, or debris gets into your child’s eyes, take them immediately to a sink with running water and pour clean water over the eyes using a clean cup.
Encourage blinking and don’t discourage crying, as natural tears are an effective solution for flushing out irritants. You can also use artificial tear drops to help wash out debris or rinse with tap water if needed.
5. Feed them healthy diet rich in eye-nourishing nutrients
A balanced diet plays a crucial role in maintaining healthy vision. Doctors recommend giving children a diet rich in fruits, vegetables, and omega-3 fatty acids to support eye health. Include local fruits that are readily available like mangoes and watermelons, which are not only hydrating but also packed with vitamins. Encourage consumption of leafy greens like spinach, and healthy fats from fish or flaxseeds.
Make sure children include citrus fruits and sources of Vitamin C, Vitamin E, and zinc in their meals, as these nutrients are essential for eye health. Proper hydration is also key to maintaining clear, comfortable vision – remind kids to drink plenty of water throughout the day, especially when playing outside.
