Glued Lens
Glued lenses function identically to Lenses except they can not be rotated.
Obtaining
You can glue a Lens in place by pummeling it with an Eggcorn in your hand.
Usage
If you just perfected the timing of an optical circuit and you are scared that you or somebody else might accidentally hit it, you can glue it in place so you can’t accidentally rotate it.
Recycling
If you want to unglue a Lens all you need to do is pick it up and place it back down. (Easier way not tested)
