Depending on season, time of day, and latitude, UF does make a difference in normal situations. They do make clear glasses with uv protection, and 80% of the reason for wearing sunglasses are addressed by they - wind, uv, insects, and so forth. Keep in mind that in most situations, you can usually turn your head away from the sun, getting away from the need for both tinting and uv protection. It takes a very confident cyclist to do the same while riding.
