I normally wear my prescription sun glasses when riding, unless it is really overcast or actually raining, or for night riding. But recently I bought a pair of orange tinted "over glasses" to wear over my regular prescription glasses. Riding with these "over glasses" had an amazing effect. Everything looked better! The sky and clouds looked spectacular. Green grass, corn plants, etc., looked almost blue-green and more vivid than with normal lighting. And I found that I could actually see the road and everything around me more vividly, and thus more safely for riding. These glasses cost less than $20 at Walgreens, and I recommend them for everyone. Even if you don't need them to be over a pair of regular glasses these would make great riding sunglasses for anyone.
