Found out one reason today at the Dr's office...
Having an allergy problem which has caused my eyelid to swell up, so the Dr wanted me to do the eye exam to see if it affected my sight. Both eyes, left eye, right eye - all 20/10 vision!

(That's the bottom line on the chart; I feel like I could've gone lower, but the opportunity wasn't there.)
Funny thing is, my sisters have both been wearing glasses since high school, my brother since in his 20's (I think), my mom & dad FOREVER (as long as I can remember), and almost all my relatives on both sides wear glasses.
I am a freak of nature!
(just hope I can keep my super powers until I'm very, very old)
