Do they make trial glasses?

I was examined for some computer glasses last week but they are too
strong because I sit so far away from my monitor. My eyes are also
sensitive to light so I'd like to try some lightly tinted glasses. The
problem is they make you a permanent pair of glasses before you are
really sure if those glasses are right for your situation (although
they will refund your money). This seems like a bad system to me. I'd
like to experiment with different powers and tints
(+75,+100,+125,rose,brown,antiglare) until I find one that I like and
THEN make a permanent pair. Have you ever heard of anyone doing
something like this?

Derar Cr113,

Subject: A low-cost trial lens kit.

There would be no problem designing a "trial frame" with
perhaps two "inserts" for two lens strengths.

With perhaps several lenses you could use
this type of "trial-lens" kit to confirm the
lens-power that you need in the "real world" when
working on a computer.

That would be a great help for you and any
optometrist who wished to work interactively
to have YOU select the lens that meets
the conditions that exist when working
on a computer.

They sell blood-pressure monitors over-the-counter.

Why not a low-cost trial lens kit to be used
in this manner. There is no legal objection.

Best,

Otis

What I di was to measure the distance from my eyes to the screen. Given that
distance in meters, take the reciprocal to get a lens power in meters. Add
that power to whatever your prescription is for distant vision. The trick is
finding a supplier, optometrist or ophthalmologist, willing to work with
you. They might have to make a centering adjustment to compensate for eyes
turning in as you they converge to a close screen.

Another thing I have done, was to buy cheap 99¢ store reading glasses in
several powers to place over my distance glasses. When I did that, I was
called six-eyes--but it worked well enough.

I had a similar thought. My plan is to measure the distance to the
screen, then go to Walmart and test cheap reading glasses at that
distance. Then I'll buy 3 pairs, one at the distance that seemed
optimal, one stronger and one weaker. Then I'll try all 3 on my
monitor. This should give me the optimal power, all I have to do is get
the right tint.

Thanks!

I've tried that. For some reason it works better for me with tinted
glasses. I've been wearing plain (without power) lightly tinted glasses
for about 10 years and it helps alot. Maybe it's the overhead
fluorescent lights.
