Tech giant IBM has patented a Google Glass like eye wear that will have red-eyed night vision capabilities, media reports says.
The device includes a sensor and ‘a comparator device’ designed to detect and contrast light intensity. When the light intensity drops below a set level, a red-color projector that included for each eye glass lens automatically projects red light into each eye. This tricks the rods into sending higher contrast images to the brain, giving the glasses a night-vision-goggles kind of a feel.
Although not promising a true night vision, 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.
The company also issued a health warning that says “The wearer of current glasses such as Google Glass is subject to the risk of a phenomena referred to as binocular rivalry and phoria- a latent deviation or misalignment of the eyes that appears when both eyes are no longer looking at the same object.”
