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.
