According to this study done in August 2017 in the University of Sao Paulo, Brazil, the UV protection on a pair of sunglasses lasted for about two years. The participants of the study were Brazilians who spend around 2 hours on average under the sun daily. So, if you use your pair for about the same duration under the sun on a day to day basis, the same applies to you. It means as soon as you complete two years of wearing your sunglasses, you have to throw those lenses in the bin just like you do with expired medicine. Let's get into the nitty-gritty of these UV rays. There are three types - UV-A, UV-B, and UV-C. The good news is that most of the UV-C rays are absorbed by the ozone layer, so we don't have to worry about them. But the not-so-good news is that UV-A and UV-B rays pass through the atmosphere and can wreak havoc on our eyes and skin. And it's not just the sun that emits these rays, but also everyday machinery like tanning beds, welding machines, and lasers. Pterygium - is a non-cancerous growth that gradually covers the white region of the eye, causing irritation and a risk of disfiguring the eye. Although, if these coatings like the polarisation one or anti-blue light coating are on top of UV400 lenses, then these glasses can certainly be called 100% UV protection sunglasses. How to test UV sunglasses at home? So, what's the takeaway from all of this? Protect yourself from those harmful UV rays! Wear sunglasses that provide UV protection, use sunscreen with at least SPF 30, and avoid prolonged exposure to the sun during peak hours. And if you're feeling fancy, throw on a hat for extra protection. Your eyes and skin will thank you. What is the ideal ultraviolet protection for sunglasses?However, make sure that you are not mistaking polarised glasses, gradient glasses, blue light glasses or mirror-coated glasses as 100% UV protection sunglasses. Because they are not! They only have coatings that save you from a part of UV light and not from UV-A and UV-B rays completely.
