Are you wearing the right glasses, you old fart!?!?
A hundred years ago I spent - and probly wasted - a ton of money on glasses. I’d get the high end tungsten designer frames, trifocals with special anti-scratch coatings, warranties, the works.
Now I just go to Costco and get cheap garden variety frames, glass lenses…and to hell with bifocals and trifocals and coatings and tints! I do a lot a little finicky work with tiny screws and bolts and there’s no help for it… I gotta take the glasses off for fussy work. Tri, bi, or single focus be hanged.
At least, according to the chart above… I am wearing the proper frames to keep the fashion police off my case. Considering my age, generous build other unsavoury physical attributes, that is something of an accomplishment indeed.
