I think the OP question as a two part question. First is about eye protection while outdoors. Second is while riding outdoors. Seems simple enough.

There is a lot written about damage to the eyes and its cumulative effect with aging. The ophthalmologist and optometrist are generally in agreement with most of the current literature (research papers).

Best place to go for advice is to the professionals. Its primarily a health question.

Pat, you're in Staten Island. NYU has a school of optometry. Give them a call.
