In contacts, I'm -9.5 in my left eye, and right eye -10.5. In glasses, about -11 and -12.0.
I've been wearing glasses since the third grade. From childhood through puberty, my vision gradually worsen. After college, it stabilized until my last check-up and contact lens fitting.
End of 2008, I went to have my eyes reviewed for Lasik. If I was eligible, I would change my Flexible Spending Account withholding to save money for the procedure. Despite the updated technology, the doctor was hesitant and didn't think I was a good candidate. My eyeball is oval, like an egg. So even with both RK and Lasik, he couldn't guarantee 20-40/20 vision. BTW, if you're in your late 30's, early 40's and consider doing lasik, the doctor may recommend monovision in one eye. Instead of giving you 40/20 vision, they back off to 75/20 to account for anticipated aging.
