Sunglasses
Colored lenses are still used to protect your eyes against UV light (UV-A and UV-B) or bright sunlight. It first seems tempting to buy a pair of sunglasses for 10 euros: you can buy multiple pairs, change them up ... because they are a lot cheaper. However, they are not nearly as high in quality. Good sunglasses or sunglass lenses must block and absorb the sun’s UV rays. Cheap sunglasses have either a much lower quality filter or no filter at all. Our eyes and brain think they are protected because the bright light seems much softer. Our pupils then dilate or open up. Our eyes are then fully exposed to the harmful UV rays. Choose the darkest lenses possible for the best filtering. They transmit much less light than lighter colored lenses. Caution! Sunglasses do not protect your eyes against HEV light (high energy visible light) or blue light.
