I have been lurking for ~8 months, the same time I started the Paleo WOE.  I
have an astygmatism...I have a lot of trouble reading street signs.  Anyway,
I got prescription glasses a year ago.  Since starting paleo, I have worn my
glasses very little, although my eyesight hasn't improved a great deal.  But
when I do consume carbohydrates (usually a can of coke), my vision gets
extremely blurry for about 6-8 hours.  Thought some would find that
interesting.
