Did you know that unprotected eyes exposed to too much sun have a higher chance of developing eye disease? The prevention is straightforward: put on sunglasses that completely or almost completely block the Ultraviolet (UV) rays. But is it really true? To know about the veracity of statements such as these we spoke to Dr Ajay Sharma, Ophthalmologist and Chief Medical Director - EyeQ.
Myth: Sunglasses Don't Protect Your Eyes
Fact: According to Dr Sharma, sunglasses help your eye by completely or almost completely blocking UVA and UVB light, which are the types of UV light.
Myth: Only Sunny Days Require The Use Of Sunglasses
Fact: "UV light can penetrate haze and fog, it is a fact," said Dr Sharma. He added that increased exposure to the sun can raise your risk of cancer, eye growth, and cataracts. "Snow blindness, a severe eye ailment known as photokeratitis, can also result from sunlight reflecting off of ice and snow," he stated.

Myth: Young Children And Infants Don't Require Eye Protection
Fact: Dr Sharma said that the sun's damaging rays can injure children just as much as they can adults. "Parents should teach their children from an early age about healthy habits to protect their eyes," he suggested.
Myth: Budget Eyewear Doesn't Provide Protection
Fact: "Sunglasses don't need to be expensive to offer effective eye protection," said Dr Sharma. He added that 100% UV-blocking eyewear sold for less can be just as effective as more expensive options.
"Sometimes labels can be perplexing. Sunglasses are said to offer 100% UVA/UVB protection by some, and 100% UV 400 protection by others. Both completely obstruct the sun's dangerous radiation," he said.
Myth: Size Is Irrelevant
Fact: The more protection sunglasses offer, the less damage the sun does to the eyes. According to the Journal of Exposure Science & Environmental Epidemiology, the effectiveness of sunglasses in providing protection is significantly influenced by factors, such as their geometry, the position in which they are worn, head positions, and exposure conditions.

"Think about wearing big sunglasses or wraparound-style eyewear to lessen the amount of UV light that enters the eye from the side. Wind-related dry eye may also be prevented with wrap-around eyewear," said the doctor.
Myth: Polarised Lenses Provide More Sun Protection
Fact: "Although polarised lenses do not block additional radiation, they can reduce glare from vehicles, water, and pavement. This can improve the enjoyment of activities like driving and boating," said Dr Sharma.
Conclusion
Sunglasses do protect the eyes by blocking UVA and UVB light, not only on sunny days but also in hazy and foggy conditions. Young children and infants require eye protection as much as adults do. Budget eyewear can offer effective protection with 100% UV-blocking options, the size and design of sunglasses play a significant role in their effectiveness. By understanding these facts, individuals can make informed decisions and prioritize the health of their eyes by wearing appropriate sunglasses that offer the necessary UV protection.
