Gluing LED Lenses

[Jaws]

Ok new problem. The optics I bought years ago are the round cylindrical kind and most of the LEDs that have been soldered have solder just enough in the way that the lens doesn't really click in properly. So it's either resolder a lot of connections or buy the more pyramid shaped lenses. I think I'll go that route. Any good priced links to this kind of optic? I've been looking but wanted to ask on here too.
