Why Children Need Sunglasses: Protecting Young Eyes from UV Damage

Most parents know to apply sunscreen before a day outdoors—but many don’t realize that young eyes are also vulnerable to sun damage. Just like their skin, children’s eyes need protection from harmful ultraviolet (UV) rays. In fact, because their eyes are still developing, kids are more susceptible to UV-related eye conditions than adults.
 

Why Are Children's Eyes More At Risk?

Children's lenses are clearer and their pupils are larger than those of adults, allowing more UV rays to reach the retina. According to the Vision Council, children receive approximately 3 times the annual sun exposure of adults, and by the time a child turns 18, they’ve already absorbed over half of their lifetime UV exposure (Vision Council).

ZEISS reports that more than 75% of UV radiation passes through the crystalline lens in children under 10, compared to only 10% in adults over 25 (ZEISS Vision). This exposure can increase the risk of eye diseases like cataracts and macular degeneration later in life.
 

The Importance of Sunglasses for Kids

Wearing sunglasses isn’t just a fashion statement—it’s a crucial step in protecting your child’s long-term eye health. UV-blocking sunglasses can help prevent several eye conditions:

• Photokeratitis: Also known as "sunburn of the eye," this is a painful condition caused by excessive UV exposure that leads to redness, tearing, blurred vision, and a gritty feeling in the eyes. It is often temporary but can be quite uncomfortable.
• Altitude Blindness (Photokeratitis at High Altitudes): At higher elevations, UV radiation becomes even more intense, increasing the risk of photokeratitis, sometimes referred to as "snow blindness" or "altitude blindness." This condition can cause temporary vision loss and extreme discomfort. Sunglasses with proper UV protection are essential for preventing this, especially during outdoor activities like hiking or skiing.
• Cataracts: A cataract is the clouding of the eye’s natural lens, which can cause blurry vision and light sensitivity. Prolonged UV exposure is one of the contributing factors to early development of cataracts.
• Macular Degeneration: This is a deterioration of the central part of the retina (the macula) and can cause loss of central vision. UV radiation accelerates this condition, which is typically associated with aging but can begin earlier with overexposure.
• Pterygium: Also called "surfer's eye," this is a non-cancerous growth that forms on the white part of the eye and can extend to the cornea. It can cause irritation, redness, and may interfere with vision if it grows large enough.
• Pinguecula: This is a yellowish, benign growth on the conjunctiva near the cornea. It may cause discomfort, dryness, and inflammation and is associated with UV light exposure.

Protecting your child’s eyes from these potential conditions is as important as protecting their skin. Quality kids sunglasses with proper UV protection can significantly reduce these risks, even in high-risk environments like beaches, mountains, and snowy areas.
 

What To Look For In Children’s Sunglasses

When shopping for kids' sunglasses, be sure to look for these features:

• 100% UVA and UVB protection: Always check the label.
• Durable, impact-resistant lenses: Kids play rough—choose materials like polycarbonate.
• Proper fit: Sunglasses should sit comfortably on your child’s face and cover the eyes completely.
• Wraparound frames: These offer better side protection from stray UV rays.
• Style they’ll actually wear: Let your child help choose a style they love, so they’re more likely to wear them.
• Warranty: Non-prescription sunglasses will have a two year manufacturer defect warranty. If you are purchasing prescription sunglasses, please check out our “Kid’s Promise Warranty” now.

Tips to Encourage Your Child to Wear Sunglasses

• Start early: Introduce sunglasses at a young age so that wearing them becomes a normal part of being outdoors.
• Be a role model: Children mimic their parents—when you wear sunglasses, they’re more likely to do the same.
• Make it fun: Choose sunglasses in bright colors, fun patterns, or with their favorite characters.
• Let them choose: Allow your child to pick their sunglasses to give them ownership over the decision.
• Create a routine: Keep sunglasses by the door or in their backpack so it becomes part of their daily gear.
• Pair with rewards: Praise or small incentives can help reinforce the habit early on.
• Educate them: Teach your child why sunglasses are important for protecting their eyes, using simple, relatable language.
• Involve sunglasses in outdoor adventures: Associate sunglasses with exciting activities like beach trips, hikes, or sports to build positive associations.
