I don't wear prescription glasses, but do wear sunglasses or clear lenses all the time when cycling for protection from sun, wind, and/or debris. Have been thinking about trying some downhill or ski type goggles this winter. Anybody with any experience going this route? I assume some of the same problems with fog, rain water, but would think the larger lens area might be a little easier to wipe with gloves than the small lenses of sunglasses.
