Fresnel Lens 3X Magnifier, Opticlens Brand 2 Pack Full Page Plastic Magnifying Sheet, 2 Count (Pack of 1)

These do the trick! Nice to have something larger that a magnifying glass to use.

Works great on my chronological Bible pages! Very sturdy. Would order again.

So, I have an old 70s flashlight that uses a bent plastic lense that ended up breaking. I had an old one of these that was scratched up that had been passed down to me ages ago, and it worked even better so I knew i had to jump onto finding new ones. This worked perfectly. It only needed a slighty bit of trimming to fit, now the thing gives off like unlike ever before! The second one I use more for its actual use as a magnifier, and am curious how it might work if used in a solar cooker! Well made, sturdy plastic with good flexibility

Size was smaller than what I was hoping for (8.5" x 11") and the sheets were pretty flimsy.

The Opticlens product is superior to MagAids of similar description. It magnifies clearly.

The two Fresnel lenses received arrived in a clear plastic wrapper and were pristine with no scratches. Those who complained that the lenses couldn't magnify when placed directly on a book or newspaper page clearly don't understand the laws of optics. All magnifying lenses have a positive focal length. Placing the lens directly on top of the page to be magnified would require a focal length of near zero. Such a lens does not exist. The description on Amazon clearly states a 300 ml focal length (just under 12"). To achieve maximum magnification, the lens needs to be positioned about a foot above the page. The only downside to the lens is its thickness (less than half a millimeter). If used for reading, taping the edges to a cardboard frame should work fine.

Bought these to read very small print in several books that I own. When they arrived there was a strip of paper across one of the lens claiming, "As described in the Amazon listing, these lenses must be raised at least 1 inch above the surface you are magnifying...". So I went back to the product listing and absolutely nowhere is this mentioned in any way, shape or form! Further, they don't magnify at all if the lens is resting directly on a sheet of paper. Further, even if you try to raise them above whatever it is that you're trying to read, they're so flimsy that the edges and sides constantly fold over distorting the type below the lens. Net, they're totally worthless, but at only $7.00 hardly worth the time and effort to repackage them and drive them over to the nearest Whole Foods and back home. Totally worthless and into the garbage they'll go!!! michaelpaul50

Good product will order again.
