Glasses need purpose!

I suppose they could add glasses requirements for far or near sighted activities, but knowing EA, they will probably come with a little swirling cloud. If they don't wear the glasses maybe it will take longer for sims to skill through say reading a book? Or their knitting will end up in failure more often? But if glasses end up being like slippers and sims will wear them in immersion breaking activities such as the slippers while sleeping or swimming, I'd rather not have compulsory glasses requirements. I don't really like using them on my sims anyway cause I can't see their faces, especially with the sunglasses.
