If I go on trekking up, I wonder whether I should wear glasses or can do contact lens.
I had experience of wearing glasses in cold weather and did strenuous exercises, and my glasses turned foggy and I had a hard time looking at things. But if I use contact lens, first I am worrying that the liquid holding my lens would be frozen, and second, without hand wash, I am not sure about the health hazard if I just use alcohol wipes to clean my hands. And would it be too dry for my eyes too? But wearing contact lens would be easier for sunglasses.
Any advice here?
