I also have the prescription problem, compounded by needing bifocals. I just can’t see the line to tie knots in my 40’s like I could in my 20’s. Like Brovarny, I bought a pair of Cocoons for $40.00 and I’m pretty happy with them. Yea, they’re big, and small children cry when I look their way, but they work very well. As ugly as I am it doen’t matter what they look like.They work! Pretty good product, really.
