I'm at that age were my eyes need assistance for some things, our local Dollar Store has reading glasses for a DOLLAR ! I have glasses all over, in the truck, the kitchen, the shop. Hey they're a BUCK ! The only real problem I have with them (other than misplacing them) is the screws tend to loosen. Superglue to the rescue ! A litle dab applied with a toothpick to each nut prevents them coming apart but if your not careful or can't really see what your doing a drop of glue can get on the lense and if you try to wipe it off you end up with a smear.. Hey they only cost a buck, no biggie right !
Step 1: What Happened
Today I was using a tube of superglue fix all on a pair of plastic lensed reading glasses when I inadvertantly got some on the lens and there was a bottle of rubbing alcohol near by, I thought "why not" dipped my finger in the alcohol and rubbed the spot of glue.. it disolved ! Buffed the lens with my t-shirt and it was good as new... hhmmmm, I looked in my box of spare parts and found a pair that had been messed up with regular superglue and saved for parts, it was a little more work, maybe because it had sat for so long. I used a bandanna as a mild abrasive and the alcohol, after a couple of minutes of buffing, I had a nice clear lens ! Of course I can't say how it will work on other materials but it definately worked on the plastic !
