Hi Ted,

I'm sure you will read Jon's excellent reply explaining
how/why you may see okay through your binoculars without
glasses and have an astigmatism.

Snort! good comparison on what you thought you heard the
doctor say. I'm much better with terms like that if I can
see them written out. I hear plenty of news clips using
words I would love to see spelled out ;-)

I am terribly nearsighted myself, have been pretty much all
my life. The problem you are now seeing or not seeing
<grin>, is a loss of elasticity with the lenses in your
eyes. This isn't farsightedness up close, unless you can't
actually see things up close without your glasses. Myself, I
could probably read something written on my eyeball <grin>.
Possibly your focusing muscles are getting a bit weak too.
Welcome to middle/old age ;-) "Reading glasses" have the
opposite correction we need for nearsightedness (i.e. +2.0
diopters, convex shape). Nearsighted correction needs
negative (i.e. -8.0 diopters, concave shape), probably about
where I am now <frown>. Hopefully I got all of the terms
right, shooting from memory here.

If you have an older pair of glasses with a "weaker"
prescription still, try using these for up close work. That
is all that bifocals really are, just different degrees of
correction to make up for the loss of focusing ability over
a larger range. Bifocals for reading are usually "weaker"
than the distance correction.

Bifocals would probably help me some of the time now. I'll
keep using an old pair of glasses for computer/reading and
the newer (more correction) for outside/birding type stuff
as long as I can. I am not looking forward to the hassle of
where to put the bifocal in the lenses when the day comes...

Either pair of glasses work fine with my binoculars, the
binoculars can easily make up for the small difference in
correction with the focus knob. However I can't use most
binoculars without my glasses now. They (binoculars) don't
have enough adjustment in the focus mechanism to make up for
my glasses prescription and still focus any distance. Rarely
is this mentioned in binocular discussions...

I am not an eye specialist, I have just read a lot about my
own woes. Your astigmatism may cause problems with using
older glasses if it has changed significantly.
