Please add an api for the glasses, so my mod can interface to them.
My goal is to unify things like the colored glasses, and bibliocrafts monocle,etc.

I assume you mean "monocle"? In any case, your intentions are a bit
unclear. Would you like to be able to create a pair of glasses that can
both see bibliocraft details as well as OpenBlocks invisible blocks?

Yes, my glasses could see openblock crayon/pencil blocks as-well as bibliocraft detials

ItemGlasses extends ItemArmor implements ICrayonGlasses, IMonocle, etc...

public static void canSeeBlocks(.....)
return true;

or something like that
