I just bought an illuminated head-mount magnifier from Harbor Freight for
$5. It's surprisingly good. The optics have little distortion and no
chromatic aberration. There are four magnifications, but the lights "focus"
at only the lowest magnification.

Those things and drugstore reading glasses are great if you happen to
have just the right interpupillary distance. I buy lab glasses from
Zenni Optical for about $35 a pair--+0.75 diopter for reading, +2.5 for
close work, coated, good frames, just the right interpupillary distance
to avoid eyestrain. Highly recommended.
