22. It's fine otherwise. Kind of hard to quantify, but I'd guess I've
lost about an inch of near focus (ie. I could hold things an inch
closer before, say about 4.5-5" away).

Oh oh, you're encouraging me. I tend to already ask a lot of questions
and logic out things in my own way. I think this is the big one
though. According to this eye chart:
http://www.keratoconus-group.org.uk/...llen_3m_A4.pdf (E
measure 45mm, I stood ~ 3m away).
my left eye is 20/50.
my right eye is 20/15 (possibly better, but it was getting blurry).
Down being -0.75, or because the quantities are negative, -1.25? :P
The optometrist said it'd be okay to wear spherical. I thought I could
do better by having two torics instead of some sort of "mixture" but
didn't realize that my compromise was off until I plugged the numbers
in to optometric toolbox (

That's okay, I'm fast learning how to do this myself. Now if I can
just find an old spam mail for one of those diploma mills... :P Heck,
those lens swapping machines look like they only cost around 40 grand
and I've still got a soul to sell.

I'm wearing glasses from a year old 'script, apparently not much
changed. I see much better with them.
Thanks for the insight!
I think I've convinced myself to just order another pair for my left
eye @ 1.50. I'll check my Alberta Blue Cross plan to see if I'll have
any trouble but I think I'll be okay; I've got an annual "spending
account" for things like eyeglasses and orthodontics that's always
gone unused. That was the setup with my trial pair (1.50 left, toric
right) and it worked great (still not as good as my glasses though),
but I always try to get better results ;0
