If you wear glasses , ask your optometrist about Velvatint (please correct me if I am wrong in the exact name, memory issues as we know!) Basically they are a lightly rosy tinted lens which actually reduces the glare of flourescent lights! Granted, this does nothing for the sun, nor for those who do not need spectacles, but they have helped me immensely andi no longer have to wear my sunglasses indoors! (and the tint itself is not obvious at all to those looking at you)
