I've a similar problem: my "near field" glasses must be changed with some "more powerful" every 3-4 years.
I was in the bizarre situation that I needed "this year" glasses for the keyboard, and "last year" glasses for the monitor's screen.
I ended up with buying special "twin focal" glasses, similar to those with "far" and "near" focus, but with dual graduation for near field. They work very well, I'm satisfied.
Sorry, but now I can't find any specification. If somebody is interested I'll look for them.
I've another problem: colors.
If there is not a very strong, white light, and some magnification, sometimes I cannot distinguish colors, especially on resistors, and cannot read those "brown on black" texts on top if ICs.
Office and lab are full of "circline" lamps with magnifier, but yesterday I installed 22K resistors in place of 3K3, and 10 boards were not working...
