Scientists have recently been able to develop a very precise, collapsible laser membrane that can be installed on any body that is curved or crisp. This membrane, after charging it with enough blue light, can trigger lasers. Researchers behind it have tested it by attaching it to contact lenses They later placed it on a cow's eye.

Expression picture is not real

But do not worry, dear scientists, scientists are not building a whole army of "devastating" laser launchers from their eyes. While we knew from fictional characters and cartoon films that laser vision can be used to make holes in barriers and buildings or to isolate bad guys The newly developed laser contact lenses can be used in more realistic and practical areas such as digital eye scans, according to the researchers' report published in Nature Magazine on May 1, Gary.

Unlike other types of lights, laser lights do not naturally form in nature, they occur artificially, include one wavelength and can be directed to any point in a very precise way, with the possibility of keeping them focused on their direction for very long distances. According to Lawrence Livermore The United States of America, the laser lights in the structure and installation of some guidance and auditing tools, and also used in some of the surgical operations, and also uses some devices with scientific use of laser lights from satellites to conduct some remote measurements for the purpose of creating 3D maps, To track the rotation of the earth.

However, most laser lights rely heavily on a supporting structure to provide some kind of stability, making the technology somewhat rigid. To overcome this limitation, researchers have devised a new method of forming a very fine plate on a glass surface and then removing the glass so that it can Apply the plate to any desired surface.

A new laser membrane has been created so flexible that it is easy to apply to contact lenses and then placed on a village eye.

In order to test the possibility of wearing this membrane, the researchers put samples on some of the normal contact lenses, and then applied those lenses on the eyes of cows, and the choice of the eyes of cows because they are similar in structure and composition of the human eye to a large extent, To experiment with them, because of course they applied them to the eyes of the dead heads of a dead village.

When the researchers exposed these lenses to the blue light, they noticed: "A bright green laser beam is distinguished from the eye of the cow." The researchers also calculated the amount of light needed to charge the laser membrane and make it release the rays, and discovered that it was within a very safe range for use on both the living cow's eye and the human eye.

These laser membranes are likely to be used as eye-wearable sensors at the eye level in identity verification procedures.
