The IBM( US tech giant ) has patented an eye wear like Google Glass that will have red-eyed night vision capabilities, a media report said. Although not promising a true night vision, the device is described in the patent to improve sight under low light by tricking the brain to focus on high contrast imagery.

The patent claims the effect is similar to that of dark rooms used in photography or the red-tinted glasses worn by some airline pilots. Dark environment with a red tinge cause the rod cells, which are the photo receptors in our eye, to send high contrast images to the brain. When the user enters a low-light environment, the projector automatically projects a low-level red light in to each eye of the user.
