I've shot hundreds of sunrises, living right on the First Coast. If you are seriously concerned, try Polaroid sunglasses.
I need to know how much of the UV is filtered out using a UV lens. Obviously, taking pics of sunsets and sunrises cannot be good for one's eyes. Is there a filter that I can buy that would protect my eyes better? I know sunglasses filter out only 50% of the UV rays in UVA -, B and C.
