The working principle of Fresnel lens
Fresnel lens is the use of a special structure of the lens to achieve the focus of light, it is flat on one side, the other side is a raised groove, can adjust the parallel light or focus light, so that the light is effectively guided to a specific narrow area, to achieve the focus of light.
Fresnel lens and convex lens are the same in function, but the shape is completely different, please pay attention to the distinction.
Fresnel lenses are most used in solar concentration, solar heating and light gathering applications. Or cooking outside as a fire starter. Fresnel lenses can also be used as projection lenses or magnifiers. They are great for magnifying print in books, magazines, maps, telephone numbers, recipes, etc. They are great as a gift or toy to childrens who need optical education.

I have found this magnifying glass to be durable, as it has not developed any scratches and is easy to keep clean. However, I will mention that due to its smaller viewing area compared to traditional lenses, I sometimes find myself reaching for a different magnifying glass when I need to examine something in greater detail. Nonetheless, the Magnifier Fresnel Lens has been a welcome addition to my collection and serves its purpose well.I had fun making some 3D prints to give myself a couple of options for using the lens. First, I made one that is just a simple frame, so I could hold the lens or put it down without touching the lens itself. The second was the same frame, but I added a handle so my son and I could hold it easier.

This lens works very well to concentrate sunlight and can easily be used to start a fire on a sunny day. The lens can also be used for close inspection of items and reading fine print. The lens is light and sturdy / thin and so easy to stow in a bag or in a pocket.

Didn’t work really good. Didn’t magnify clearly or start a fire which I was using it for.
