Speaking of Vision -- How 'bout Progressive Bifocals?

some time, but lately I've realized that it has become downright
dangerous. (Moreso driving a car, actually.)

Jay,

I've had progressives for a couple of years now. I have to wear
glasses to pass the distance part of my medical. I can actually
read the charts just fine if I don't look through the glasses.
However, raising them everytime I wanted to look was getting
to be a pain.

The key to the progressives (and probably any bifocal) and
flying is to make sure they set the "line" at the right point.
The first pair I have are set way too low. The second optician
and eye spent some more time tweaking that and they are much
better.

This has been my experience as well. I tried progressives and didn't like them due to the blurred peripheral vision
that others mentioned. It was especially evident while driving and was very distracting. I went to the lined
bifocals for a year, then gave the progressives another shot with the line moved up. It made all the difference in
the world. Wouldn't go back for nothing,

I have had NO problems adjusting to the progressives, from the very first
moment I got them last week.

Yet others complain of nausea, blurry peripheral vision, etc. Why?

I think I've got it figured out. MY eyes are so bad, distance-vision-wise,
that the "reading" glass portion of my new glasses is really just a weaker
"distance-vision lens", rather than a true "reading glass" lens.
Basically, the lower part of my new glasses is probably the same
prescription as my old distance glasses, circa 1985 -- and they simply allow
me to see the charts farther away than 6 inches from my nose.

This contrasts sharply with Mary, who has perfect distance vision, and
really needs "reading" glasses to force her eyes to focus up-close. I
think it is these folks who have great difficulty with the progressives,
since the lens is basically going from "clear glass" to "magnifying
glass" -- causing great distortion in their peripheral vision at the
"edges".

Guys like me simply have a slightly weaker correction at the bottom of my
lens, and that is not such a dramatic, vision-altering distortion.

Make sense?

Lucky you!
My left eye is farsighted, my right eye is nearsighted.
No way I can flip my glasses upside down as some suggested. :-))

You might have missed one of my posts on the need for close up work while
looking out of the top of your glasses.

There is actually a type of lens made that has your close-up prescription on
the bottom, *and* the top, for when you can not see your work by looking out
of the bottom of your lens. There is even a name for this configuration,
but I do not remember what it is.
