I'm looking for advice/opinions on wearing glasses or contacts on a thru-hike. I normally wear contacts with no problems, but I'm wondering if wearing glasses for my hike next year wouldn't make more sense? I wear the kind of contacts that you leave in for a month so it's not like I'd have to change them every day, but one of my biggest concerns is how I would get my hands clean if I needed to change them on the trail. Also, the added weight of contact solution seems a little silly. On the other hand, glasses can break, which would suck. I would really appreciate some feedback back on this.
