Default Speaking of Vision -- How 'bout Progressive Bifocals?

Periphial vision is still fuzzy - I have to turn my head way farther to
the right or left and adjust the elevation of my head to make out
detail to the side.



Thanks, Randy -- but this doesn't make sense to me. The "progressive"
part of the reading lens starts below the half-way point down the lens
-- so why would they have ANY effect on peripheral vision?

Well, unless you're looking down, I suppose?


Jay, I'm not Randy, but I'll reply as I have progressive lenses. Mine
don't have the prescription in the bottom uniformly across the bottom as
with more conventional bifocals. The different presecription is more of
a circular shape and things read through the lower half of the lens are
only clear if nearly centered in the lens. The prescription on the elft
and right sides of the lower halves of my lens is about the same as the
prescription on the top half of the lens. So, my peripheral vision,
whether looking through the top half or the bottom half, is through my
distance prescription.
