I've not had one who thought it bad (it isn't). BTW, one can do it with
glasses too in lieu of bifocals. In fact - if you need trifocals - you can
do it with bifocals. I did...got tired of the trifocals, made my head bob
around like a dolly hanging from a mirror in a chevvy. Now I use
progressives. Even better.
Whose gonna clean up the coffee you just made me spit up! (-: My take on
trifocals, exactly. They made my neck hurt I was doing the spring-head doll
dance so much.
Went back to bifocals but just might try progressives - if I can get them in
my RX. I've got some bizarre astigmatism that causes lens makers fits and
makes it very hard to use contacts successfully.
I remember a movie where guys in EMT suits come to cut some guys heart out
and as he protests they say: "This IS your signature on the donor card,
isn't it?" If I could remember the movie's name, I probably wouldn't need
Okay with him.
It's roughly equivalent to wearing a hearing aid in only one ear or walking
with a single cane.
If there exists any concern, routinely switch which eye has the contact. If
you're like most people, the shape and size of each eyeball are the same as
the other, so you only need one, er, "shape"(?).
Bi-focal contact lenses are also available.
One other point...
Everyone has one dominant eye. If you do the near/far lens thing, put the
prescription for the activity you most use (near/far) in the dominant eye.
You can determine which eye is dominant by pointing at something. Now close
one eye...are you still pointing where you were? If so, the open eye is the
Then close the other eye.
If you'll look carefully when you point you'll see that there are *two*
fingers out there pointing (unless you only have one eye). When pointing,
our brain ignores one of them and selects the dominant eye as the "rear
Whoosh! Right over your head. :-)
I wasn't talking about eyesight mechanics or the brain's
interpretation of the light rays entering either eye.
I was simply stating that I was still *pointing* to the exact spot
that I was *pointing* to before because my arm didn't move.
Been there, done that! (-: Ratshack used to make a serviceable magnifier
with a small higher mag inset lens and a battery powered illuminator. About
6 bucks a piece and worthless after the take one hard fall. Also, the
battery contacts and switch are cheap sheet metal and they fail after a
while but I wouldn't (actually couldn't!) live without them in each and
every room of the house. Paint pens work beautifully on them, FWIW, but
they're plastic and I assume the solvent eats right into it, assuring good
I have an even older friend who's too vain to wear his glasses or use a
magnified and lately he's burned up a hard drive putting the molex *keyed*
connector on backwards, set DIP switches wrong by not realizing he was
looking at them upside down and broken a ribbon cable with again, a keyed
connector on the end by trying to connect it backwards. Well, he didn't
exactly break it, he worked at the connector so hard trying to fit it the
wrong way that a sharp metal RF shield edge just sawed right through it.
Eventually, he'll get the idea that being able to see is worth the indignity
of wearing bi or tri-focals. I hope. (-: I've gotten the message from
Mother Nature loud and clear. For now. I hear that hearing is going to be
the next thing to go. What's that old joke . . .?
re: "...so that they can be read in dim light by old fogeys?"
Others have already suggested reading and/or magnifying glasses.
I'll suggest turning on a friggin' light! ;-)
(See ya..I'm off to the dollar store for reading glasses and a
One handy device inherited from a dedicated handiperson is a fluorescent
lamp with a magnifier in the center. PIA if you need to move it, but
the lighting and glasses bit doesn't always work.....my condo has large
windows on all sides but the lighting is often not sufficient for older
eyes and fine work. New prescription, so that's not an issue.
I have a lamp similar to this mounted on my workbench. Mine has a flip-
up cover to keep dust off of the magnifying glass.
And yes, I have used it to determine socket size many times!
Also great for removing splinters, especially tiny metal ones.
