There are mosquitoes on the Appalachian Trail; but I’m sure they know that by now. I think I still have my own pair of “funny glasses” that I wore for the trip – big, thick-lensed, heavy, needed Croakies to hold them on. Ah, the memories!
I have also worn contact lenses, which are somewhat of a chore to bring along since they require saline solution and cleaner, etc. Backup eyewear is essential. Sunglasses are important to have if weight allows, otherwise a broad-brim hat (I wore a ball cap) does the job.
