Newest police weapon: The "stun ray"

The StunRay is a little different; it uses bright light, not a laser. Apparently, the ray works by sending the optical nerves into overdrive because of surplus stimulus to the retina. Todd Eisenberg, the laser’s inventor, told Scientific American it was the “inverse of blindness.”

Physically, the gun is small and light, weighing about as much as a bag of flour. The width of the beam itself is adjustable so the weapon wielder can change its severity based on the threat level. It’s also got an infrared illumination tool for covert surveillance operations at night.

According to the patent claim, incapacitation occurs due to “disorientation, reduced cognitive abilities or temporarily loss of fine and gross motor skills.”
