I think this tag was just created by Pablo maybe as a mistake for the lenses tag.
So I'm not sure if it should just be deleted, or synomized with lenses (Wikipedia says "lense" is an appropriate but uncommon spelling of lens).
I also kind of think we should add a tag for "lens" and synomize it with these two.
I don't have permission to even request the synonym, but maybe someone else can do it?
