When I got a new pair of progressive lenses they bothered me for knitting. So I went back to the doc and told them to fix 'em.
We'd discussed where to put the 'view' of each prescription...I have 3...one for reading, one for knitting distance, one for driving & tv. Anyway, they fixed them! I brought my knitting up to the doc office, and showed her where I need the 'view' to be.
The price we pay for glasses these days, they can just GET IT RIGHT.
Also, I used to suffer eye-strain...glasses or no glasses...until I got an OTT-LITE to knit under. It replicates DAYLIGHT perfectly. No more strain. And, you don't get as tired in general. I think that's why I can knit til 3am each day! I know I couldn't under normal incandescent light bulbs.
Anyway, for what it's worth...
