How much protection do your eyelids give you from the Sun's rays?

Question

I'm guessing no protection in terms of X-rays but what about UV etc?

Answer 1

there is significant protection, if they are closed-if you keep them open, not much-use a hat, use sunscreen, and stay in the shade-have a good summer.

Answer 2

My eye doc told me cataracts are starting, don't go out without 99+% UV protective wrap around sunglasses.  I found on a web site that with cloud cover, UV rays are stopped if the cover is "heavy."  "Light" and some "moderate" can let the rays through.  As there was no definition of "moderate" and "heavy" and there was no instruction on how to tell if the cover is "heavy enough", I wear 99+% UV stopping, yellow, "shooters" wrap around glasses when the  sun is covered.  When the cloud cover is "heavy" its usually raining hard, so I'm inside or well covered up.

Answer 3

Err. none. the actual visible light is mostly shut out buy the other two will pass through the skin.
