This things really works. I started a fire with it.I just wish the man who invented it would have recognized early on that he was going to be an inventor and that he should change his name to something cooler.Like "Orlando Lens" or "Lily Lens" "Alvarez Lemsor ... Oh well, I guess we're stuck with Fresnel.

I bought the 8.3" x 11.75" Large 3X Fresnel Lens Full Page Magnifier, one for myself, one for my sister, primarily for reading books, prescription bottles, and ingredient panels on products in stores because I have some visual difficulties arising from Lyme Tick Eye Disease.I had NO idea there were so many other great uses for a Fresnel lens which appeal to survivalist/preppers like my sister and me! You can start a fire with it, much like you would using a hand-held magnifying glass, only faster and better! It is extremely useful for reading paper maps on driving trips. It is durable, flexible, and easy to store.I can also use it in my organic garden, to inspect my seedlings, and check my vine fruits for any destructive insects.I plan to buy more this spring for my 3 school-age grandchildren. They can use it to explore nature (insects, leaves, plants, flowers), for their viewing their stamp collections, and for examining fossils or seashells they find on the beach. Makes a great gift for recipients of ANY age! RECOMMENDED!
