i can't see

so I have had some problems seeing, so I went to the eye doctor today and I need glasses (along with the rest of the world it seems...). But I don't need glasses. Confusing. Apparently I have a weak focusing muscle (who even has that!?), and unfortunately eye muscles aren't ones that you can work out, so I'm getting glasses so my eyes don't have to work as hard. Obviously I'm getting these ones.
