How would you know if your sunglasses provide uv protection?

How would you know if your sunglasses provide uv protection?

Sunglasses & UV: The best sunglasses should block 99% to 100% of uva & uvb radiation. Always check the label before you buy. Labels that say “uv absorption up to 400 nm” or “meets ansi uv requirements” mean the glasses block at least 99% of uv rays. Those labeled “cosmetic” block about 70% of uv rays. If there is no label, don’t assume the sunglasses provide any uv protection. Dark "sunglasses" may not block uv. ...Read more

Ultraviolet : Ultraviolet (uv) light is harmful to the eyes, especially large amounts over long periods of time. In the United States, all sunglasses are required to block a very large percentage of the uv rays. The darkness of the sunglasses does not affect the uv filtering ability, since uv light is invisible and the uv blockers are clear. It is true that darker the sunglasses will open the pupil more and thus let in more uv light, but since almost all of it is being filtered by the sunglasses, this is not something to worry about. The exception would be specific eye diseases such as retinitis pigmentosa, in which extra high uv protection is a good idea. ...Read more
