Is there any evidence of any form of eyewear in TES? What do they do for bad eyesight?

Well they have magical healing so I'd figure a simple healing spell or potion would cure most maladies of the eye even injuries,But if you lose an eye its gone for good,They dwemer seemed to have developed some form of lenses at least...I'm not sure about the last part.

Didn't Morrowind have some sort of glasses on some helmets?

Goggles, not glasses. Think ash storm. Do you really want that stuff going into your eyes?

The PGE1 says the lenses are made out of resin.
