The old story of contrast.
Also many times the display uses the light shining on it for its light
source.
Putting the lens in front of it blocks that light.
=46or some reason the lamps on the standard reading lens just don't cut
it.
Many of the newer laptops are starting to have the same problem as well.
It makes me wonder what a scream there will be when all those baby
boomers get blind and can't read all their marvelous toys any more.

I used to use the regular Optacon lens a lot with LCD displays on
calculators. I suspect a lot of modern calculators no longer use OEDs
since it takes extra power to light up an LED. What I haven't figured
out is why the displays on so many phones these days aren't
distinguishable under an Optacon camera.

I have one but all the new calculators that I have won't work with it.
It is a lens with no lamps in it, and therefore, doesn't always work
with the new calculators that use ambiant light for the display.
It also has a limited size of characters for which it works best.
Personally, I haven't used it in years.
I'll look around for it and get back to the list on the issue.

Subject: Optacon calculator lens
Good morning list,
If anybody has a calculator lens they don't want, I would love to have
it, (probably along with just about every other user on this list!) From
what I understand, the calculator lens didn't have rollers on the
bottom, but it looked like a regular lens.
My e-mail address is at the bottom of all items I send, so you can
contact me off-list; thank you.
