hi there, WHen i got my eyes tested years ago i was told i am okay to drive without any corrective lenses, any worse and i'd have to wear glasss or contacts while on the road. since then however i'm sure my eyesight has become slightly worse (i'm going for checkup this week). I never ride with my glasses on because the frames aren't flexible enough and i've never had any problems but now i feel that its safer to have some sort of corrective eyewear on while riding, especially because rider need to be extra aware of surroundings. I've never worn contact lenses before, but i guess i'd have to with the helmet on. which brings me to the main point of this post... Quite often i flip up the visor to talk to fellow riders at the lights etc, in peak hour and going speeds under 60km/h i just tend to leave it up if we are going to stop and the next light and communicate anyway. this makes my eyes feel "gritty" sometimes and they can get really dry. how do contact lenses behave under the same conditions? will my eyes feel extra gritty if crap goes in my eyes? will the contacts dry out and stick to my eyeballs? thanks!
