Just curious, I saw some posts where people do not wear their contacts on the trail. I could see this being more convenient, but since I have poor vision 12.75 diopters. I see better with contacts so I wear my gas perms on the trail while hiking and change over to glasses for evening. I've only hike a week at a time. Do contacts become more of a nuisance with time? For me if I did a thru-hike I figured I might need mail drops to find the right solution, and perhaps carry a second pair in case I lost one.
