I rarely bring contacts and just wear my glasses on the trail like I do around town. Â One reason for me is that as I’ve aged, my “reading glasses” (to do any close work, or increasingly to read a phone / GPS screen) are to take off my distance glasses. Â That’s easy with glasses and hard with contacts.
But when it’s going to be rainy or cold and my glasses would fog up, then contacts can be a nice option. Â I use disposable ones so if I get dust in my eyes, I can just toss them and I’m not worried about keeping them perfectly clean between uses – I just toss them.
A very small container of saline is helpful for a final rinse of your fingers and to rinse off the contacts before you insert them, if anything gets on them.
A mirror is maybe a necessity until you get practiced with inserting and removing them. Â If you’d bring a compass anyway, the mirrored compasses make nice stable mirrors you can adjust the angle on easily.
My vision isn’t so bad that I couldn’t function okay on the trail without anything, but I still always bring a back-up pair of glasses – there’s beautiful scenery out there!
This works better than you’d think: you can wear *one* contact at a time. Â Then, in my case, I have one far-sighted eye and one near-sighted eye. Â You use binocular vision less than you think you do. Â I usually start the day with both, but then when I need to do some close work, I remove one, just toss it, and leave the other one in until I’ve gotten to camp. Â If you did that from the start, you’d cut your costs in half.
Back in the 1970s, my usual hiking buddy insisted on bringing his contacts but you had to boil them, etc each night to treat them and it was pain to fire up a stove at 12,000 just to deal with contacts. Â I’ve been put off a bit by them ever since (even though that’s no longer the case). Â I also like having a UV-blocking, branch-blocking, semi-dust-blocking glasses lenses in front of my eyes at all times, so I don’t mind wearing glasses. Â On a halibut-fishing trip or hunting in the Aleutians, there are no branches or dust and often no sun, so contacts alone are fine. Â Otherwise, I’d bring sunglasses for the added protection from sun, bush-whacking, and dusty winds when needed. Â Or skip the contacts that day and use my prescription glasses.
It is nice, because of contacts, to be able to buy sunglasses off the shelf instead of special-ordering prescription sunglasses, but Zenni Optical now makes prescription sunglasses pretty dang affordable by ordering online (single-lens, clear from $15, prescription sunglasses from maybe $25).
