I have mono-vision contacts and wear drug store readers for sewing. when I hand stitch binding I take everything off and just sew with my nose 2" from the binding. The amazing thing here is that in the last 3 years that I've been quilting, my vision has actually improved for the first time EVER!!! I got used to my mon-vision in a week or so, but then the next spring, when I went to my kid's baseball game, I had to re-adjust! My near eye wanted to look AT the fence and my far eye wanted to look THROUGH the fence. THAT was a little weird, but I adjusted after a few games!
