I wear them & I admit, I'm addicted. Regular glasses are worthless now because I can't see up close with them. Normally, I wear contact lenses all day with a pair of +150 readers for anything up close. Which is almost everything involved with my job as a fleet mechanic. It's a big pain in the ass, but it's true. When I get home in the evening & I'm just wearing glasses, bi-focals are my only choice.. Never wore them on my bike yet, but they're nice when driving my truck. I can see who's calling me on my cell or change the radio station or dial up a CB channel. It really sucks when I'm hunting & I have to wear them to read my GPS or compass. I don't consider myself old yet ( 46) , but it sure sucks having to have worry about the proper glasses in my pocket at all times just so I can see the simplest things. I shouldn't bitch - at least I still have my eyesight. The advantage of bifocals over contacts is that with bifocals you always have your glasses on anyway - just tip your head up & everything's clear. After a short time you'll be so used to them that you won't want to be without them. Sucks getting old, doesn't it ?
