Review title is Yes, size matters. [SEP] I have two pairs of glasses that lost a screw each.  Years ago if I lost a screw I'd go to the local drugstore and buy one of the little combo screwdriver, magnifying glass, that came with about a 1/2 doze screws. I don't ever remember those screws not fitting whatever glasses/sunglasses I tried to fix.<br /><br />I looked at a lot of kits that had dozens or hundreds of screws of varying sizes. I read through reviews and even with the huge selections and &#34;variety&#34; of screws there was a surprising number of people who complained that none of the screws fit their glasses.  I decided to steer clear of those and settled on this kit because of the variety of other items included.<br /><br /> However, after pulling out my magnifying glass I tried each screw size one by one and none fit.  Two were too large and one was too small.<br /><br />Since the smallest went through the hole I decided to try using one of the nuts that came with the kit. First, I couldn't tell what fit with what because there is no guide. Second, after trying the nuts on the smallest screw I found they didn't fit.<br /><br />I finally just stripped a piece of copper wire from some speaker wire I have laying around and threaded it through the hole in the glasses and tightened it down.  So, at least I have something that will hold until my eye appointment and I don't have to worry about the lens popping out.<br /><br />I'm keeping the kit.  I'll probably just pick up a few screws from the optomitrist once he lets me know what size I need and replace the ones that are in the kit so it's not  a complete loss. I'm not sure when, or if I'll need the other items that come in the kit.  Also, there are things that came with it that I have no idea what they are for. One of those are some very tiny plastic cones.  I'm sure they have a purpose...
