I've been in progressive lenses for about thirty years, as seen in my avatar, although those aren't my latest frames. When I planned to get them, I got all kinds of advice about how they'd make me feel dizzy and make me nauseated with the "motion" they created, and so on. I put them on and saw better, and easily learned to use the several areas of the lenses -- seem better than the distinct lines to me, and don't look quite so elderly, though I may. Specs are traumatic to some guys, but they seemed to suit me, bookish fellow that I am. I got tired of squinting at the blackboard in college, and finally got fitted for glasses going for officer candidate school, which I didn't make. After that, it was glasses optional for a few years, and then they just became a daily convenience. No hanging them on a chain or roosting them on my forehead. In boot camp I reminded all the guys with "part-time" glasses to bring them to the written test, in my capacity as "education officer" in the boot company.
