Depending on the strength of your prescription, you may want to experiment with stronger reading glasses. I've found that I'm pretty happy using quite strong reading glasses while doing any type of sewing - these glasses are strong enough that objects at only 15" are starting to get blurry (which means I can't iron with these glasses on). I have glasses with progressive lenses that I use for most of life, but inexpensive reading glasses are preferable for me for sewing.
