RE: [magnifiers] Magnifier standards

I'm told diopters is a more accurate way to compare mags. The $3.99 price
would have been a red flag for me.

Subject: RE: [magnifiers] Magnifier standards



I do believe magnifiers vary in quality, though I'm not sure how this works.
I had a low vision specialist once show me two magnifiers that were both 10x
power, but I was not able to see the print with one and was able to see it
with the other. He said the difference was the optics, and of course the one
that was better was much more expensive, by several hundred dollars. So I do
think price makes a difference in quality, which could affect the resulting
image quality.

Do you mind mentioning which company you bought it from? I'm just curious.

Jen

Thanks for the information. These magnifiers do say 8X and 10X they don't give the diopter. They are round and they are clear image just not as large as they...

Magnifiers should really be selected based on their diopter power, this is the standard mewsurement. There is no standard for magnification. In a message...

The closer the magnifier is held to your eye, the greater the magnification will be. So if you hold the magnifier close to your eye and move the page you are...

You might want to search under Geology hand lenses. You can buy a fine B&L 10X magnifier for under $50. Any more than $100 is always a rip-off. My favorite...
