Troy, they make some stick on optical lenses for dive masks that are just an inch or so wide. Lots of folks who don't want to pay for a prescription lens in their dive mask use them. They might work for a pair of sunglasses for your knot tying or other close up work. they adhere without adhesive. might be worth a look at.

I just carry a pair of walmart readers in my pocket for when I have to see that well. I can tie a fisherman's knot blindfolded but if I have to tie a bloodknot or a palomar I have to use my glasses.
