Can smoking effect your eyesight?

Rarely: There is a condition associated with both smoking and drinking called tobacco-alcohol ambylopia, that can result in blurred or even double vision, and relates to problems with the eye muscles. The physiology of it is not clear to me, and it is not commonly seen. I do not know of any other ways smoking can effect vision other than causing dry eyes. See an optometrist or ophthamologist for opinion.
