I sure wish I could improve my eyesight! Distance is no problem except for the astigmatism, just can't be on the computer, read, sew, quilt without different glasses...for each one! Still can't time my quilting machine, even with a magnifying glass, so my hubby has to do that. Definitely could not do the "glasses on a chain" thing, or I would have 5 pairs hanging there and I would never know which one to have on! :shock:
