Dear Bucky,

There is no "perfect" answer here -- but here is one possibility.

I'm probably using the wrong terms, but hopefully you'll get my point.
If I have a contacts prescription of -11 sph, -1.25 cyl. What would
happen if I wore spherical contacts -11 and left the astigmatism
uncorrected? What would my "equivalent" vision be like?

The spherical equivalent would be:

-11 - (1.25/2) = -11.62 diopters spherical equivalent.

You could go for a slightly stronger -12 diopters
(you optometrist could help you with this).

You might have 20/25, rather than 20/20 -- but
only by reading your Snellen could you tell this.

If your Snellen is better than 20/40, by you
would pass 98 percent of the DMV Snellens.

Best idea?  Go ask you optometrist about
this possibility.

Best,

Otis

The reason I'm asking is because they do not make disposable contacts
with my prescription, only custom-made torics. But they do have
spherical disposables at the same power. I'm just wondering if I could
see decently (everything except reading and driving) without correcting
astigmatism.
