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. <grin> =20 J. R. ---------------------------------------- J. R.

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. Regards, Jerry =20 "Westmoreland, J. R."

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. J. R. ---------------------------------------- J. R.

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.
