IBM patents night vision eye wear

IBM Nightvision glass

IBM has patented an eyewear that has the red-eyed night vision. The name is a bit misguiding as it doesn’t do much to improve the night vision, however, the device as described in the patent is able to improve sight under low light conditions by making the brain focus on high-contrast imagery.

The modification to the Google Glass is in the form of  a sensor and a comparator device that is used to detect contrast light intensity. As the intensity of the light decreases and goes below the visible range for the human eyes, two projectors get activated and cover the user’s eye in red light that activates the night vision.

You might be wondering why the red light is used. The reason is quite simple, yet ingenious really. You might have seen cats have a red glow to their eyes while they roam around in darkness during the nighttime. They have natural colors in their eyes that enables them to have excellent night vision. Their eyes are so developed that tigers have 6 times better night vision as compared to humans, a fact that makes them excellent predators in the night time.

IBM has adapted this biological mechanism in a very interesting way. The red color helps the rod cells, which in simple ways are photoreceptors to your eyes and makes them deliver high contrast images to your brain. These projectors imitate red light going out in the environment and activates the rod cell for such images.

The patent further claims that the company’s unique technology capitalizes on the fact that projecting the light into both eyes through two separate sources removes the side-effects of binocular rivalry and phoria.

We are yet to see how this technology will evolve the Google Glass. The Glass is yet to be made available to the public.
