1- Aim to protect your eyes first and foremost. Excessive exposure to UV radiation can cause a variety of problems for your eyes such as cataracts, burns, and cancer.
2- If you want your sunglasses to protect you from these risks, look for pairs that block at least 99% of UVB rays and at least 95% of UVA rays.
3- Don’t buy cosmetic sunglasses, they usually don’t offer any kind of information about the level of protection they provide.
Lens color and material
They color of the lens both affects your fashion statement and how well you detect contrast and color differences.
Some colors enhance contrast, which can be useful; however, this is often at the expense of color distinction, which can cause problems (when you’re driving, for example, and need to be able to clearly differentiate the colors of a traffic light). Some sunglasses even come with interchangeable lenses so you can change the color easily, depending on what you’re doing.
Look for distortion. Hold the lenses up in front of the sun or light bulb. Start moving the sunglasses, check that wave distortion doesn’t happen. If it doesn’t happen, this is a good sign.
