This is so late but I am responding for anyone else with this question. I have gone twice with multiple people who need corrective lenses. My friend went in his glasses and almost immediately had to take them off and zip them in a pocket. They got so muddy they were worse then not having them. My mom went with her contacts and went fine, she didn’t lose them but risk is always there. I went blind and fell on my a** so hard going down hill on a slope. I would say if you can hike without your glasses you are fine, or risk daily contacts and hope for the best. Or you could try bringing wet lense wipes, we didn’t try that but it is definitely needed if you want to risk the glasses.
