Well, I found an abstract of a study that measured UV and visible light transmission through eyelids. It found that while up to 77% of visible light is transmitted, “negligible” amounts of UV make it through (the URL is extremely long, and the Fluther text editor won’t allow me to make a link out of it, but if you’re interested I’ll PM it).
From an indoor tannin site (not what I would consider a definitive source comes this: “Your eyelids block less than 25% of the damaging rays. So keeping them closed when not wearing eye protection is not good enough!” On the other hand. state law mandates protective eyewear there.
