■Key Specifications/Special Features:
◆Fresnel Magnifier Bookmark
◆Material: PVC
◆If you have ever looked at the lens of a magnifying glass, you know that it is thick in the middle and tapers down to nothing at the edges. In other words, it is shaped like a lentil, which is where the word lens comes from. It would not be very easy to make a big magnifying glass lens because it would be thick, heavy. Now, the thin piece of plastic you are browsing is called a Fresnel lens. It is flat on one side and ridged on the other. It is a high tech product, which is inventive by a French called Fresnel.
