I have to wear damn eye protection at the machine shop all day long. I hate it, but I wear 'em. I figure, as long as I have to wear them anyway, might as well have the best vision possible, so I have them mildly corrected for near-sightedness. Trouble is, when I'm doing real close up reading it's hard to see with them on. The next stronger correction for seeing distance will demand having bifocals for the close work. BIFOCALS! Waaaaahhhh 
BTW, I insist on having glass lenses instead of plastic for the scratch resistance. I know that's not very common by the reactions of the optometrists that make them. "Are you sure you want glass, they're so heavy?" Hell yeah, your damn plastic would be scratched inside of a week, screw that! :disgust:
