Why doesn't "Occulus Reparo" REALLY WORK?

[thghtswopurpose]

Thanks a lot JK Rowling.  I bet there's loads of little kids out there saying, "Hey, its ok.  If my glasses break, its no big deal.  I'll just reparo them back together."  Well you CAN'T.  And tape on glasses is still a bad look.

On the other hand, I can wear my contacts during the day.  But I can't really afford new glasses or the newer prescription for my contacts so its still really annoying.
