Scientists are working hard on making another breakthrough in the world of contact lenses the next goal will be to allow wearers to shoot out lasers. Yes, you read that right, no it is not a new superhero or comic book character. A scientist has recently developed a laser that can be carefully placed on a membrane, meaning you could shoot lasers from your eyeballs. They have tested the new contact lens on cows, effectively creating cattle with laser beams coming out of their eyes.
The first ultrathin membrane laser can be attached to any fixed or curved object, even very delicate ones like eyeballs. Once charged these lasers can emit a green laser, don’t worry though this is not being made for warfare. These lasers are being developed with more of an identification use in mind, a way to open security doors or enter into restricted areas of a building.
Though who knows where the future developments will bring them, will farmers of the future need to protect their livestock at all? With cows being able to shoot lasers from their eyes: any protection will no longer be needed.
No need to fret just yet though, no one is creating battalions of cows wearing deadly lasers that blast from their eyes. Researchers have been able to successfully place their membrane laser on the cow eyeballs, which is a great first step for this type of technology. Laser light is very interesting for passing security scans because unlike other light sources it just shoots in one direction and uses one wavelength.
The problem has always been they require a solid supporting structure to correctly emit the beam, now that researchers have been able to overcome this barrier with their flexible membrane attachment we could find lasers being mounted onto many different technologies of the future. For example, they could be attached to bank notes or security documents as an extra layer of fraud protection.
