I have had glasses since I was in middle school and never used contacts. A few of my runner friends who wear contacts use glasses or goggles (or nothing) to run because they say that their eyes dry out when they run and the lenses fall out all the time. If I got contacts and wore them while road cycling, would they be likely to fall out? If I wore a pair of sunglasses to block the wind, would my eyes dry up? I would probably always be wearing sunglasses, just cause it would feel wierd not having them on my face. Thanks for input.
