When it comes to covering up in the sun, the first thing you think about is probably (hopefully) protecting your skin. But what about your eyes? Sure, wearing sunglasses makes you feel cool, like a film star hiding their identity, but they also serve a very important purpose; protecting your eyes from harmful ultra violet rays. UV causes premature aging to the eyes, increases your chance of getting cataracts, macular degeneration and growths on your cornea.
It is crucial that you select your sunnies not just for their appearance but for their UV protecting ability. For sunglasses to serve their true purpose they should offer 100% UVA and UVB protection. However, can you trust the claim of 100% UV blocking and do cheap sunglasses perform as well as expensive ones?
Dr Dennis Fong, professor at the School of Optometry at California University put 11 high street sunglasses, costing between $10 and $20 and multiple designer sunglasses, costing over $100 to the test.
A spectrometer was used to measure the Ultra-violet rays that passed through the lenses of the sunglasses. First up were the designer brands, which included Ray Ban, Coach and Smith. Fong found that all the high end sunglasses did block 100% of UVA and UVB as the spectrometer measured no light passing through the lenses.
Next up were the cheap glasses which claimed to block out 100% of UV light. When being tested they all lived up to their claim and performed just as well as the designer brands.
So why do people buy luxe sunglasses? Fong believes they are more durable and offer superior comfort for the wearer. Whether you buy cheap and cheerful shades or luxurious Prada frames, as long as they have 100% UV protection you’re good to go.
