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.
UV Protection with Contact Lenses. You probably know about the damage the sun's ultraviolet (UV) radiation can do to your skin. But do you know about the damage UV radiation does to the eye? This UV exposure adds up over time: The exposure while on the beach as a child combines with sun exposure as you age, resulting in damage later in life. The rays that pass through the pupil of the eye are absorbed by the lens of the eye. This UV radiation may cause cataracts in the lens of the eye.
