If the contacts are fitted properly, and you have not wrecked your eyes from abuse when you was younger, then no problems. When I was younger I always rode and raced with contacts. Much better depth and peripheral vision. And with glasses on sharp impacts they jar/move, ain't no way around that. Now when I try them its not good, they move, dry out and fall out. The optometrist always asks while looking at my eyes how long I have been wearing them, but never refuses to sell them to me, #%@#^! Ah the lasik thing, it has ome a long way. I am still concerned I will lose my close up detail vision. My eyes are VERY bad also, far sighted. I am responsible for getting the air force to change there rules on glasses back in 70 something. Overall it suks!
