well the UV rays can indeed go through your eyelids, but like the others i've closed my eyes and am fine....if you dont tan 365 days a year for 90 years i dont think you'll be in danger...also one thing to consider is if you wear contacts....most are now UV light protected which definitely helps to block out the rays.

The retina is a layer of tissue in the back of the eye that is able to sense light. Retinal arteries may become blocked when a blood clot or fat deposits get stuck in the arteries.
