I cannot ride without glasses due to bugs and wind. On the lens colour- I have a clear lens that I use for night riding- a Dark lens that I use for bright sunlight- A red lens that is used for those Bright but overcast days and a Lens that is supposed to be for night riding but as it has a yellow tint- Is not that good. The yellow affects me under certain types of street lighting in that Certain objects close in colour- merge together. Those yellow lens's are fantastic at Dusk though. They do allow you to see more. Did not believe it untill I went to a golf course and finished up playing into the Darkness. I could see the ball after I struck it and could tell the direction it had gone. All the other golfers lost sight of the ball as soon as it left the club.

The different colour lens's are not all Bling. Some of them do allow you to see better- some suit your eyes better and some are next to useless in the wrong conditions.
