US tech giant IBM patents Google Glass-like night vision eyewear

IBM, the US based tech giant, seems to be keeping a close watch on Google. This js because the company has reportedly recently patented an an eye wear which is quite similar to Google’s much-famous Google Glass. Apparently, similar to Google’s product, the IBM offering would also come with comred-eyed night vision capabilities.

Although the device won’t be providing true night vision, but according to the patent it will have the capability to improve sight under low light as it will be successfully be able to trick the human brain in focusing on high contrast imagery.

According to certain reports in the media, what sets the IBM product apart from its Google counterpart is the fact that the IBM one will have a sensor and ‘a comparator device’ designed to detect and contrast the intensity of light. Whenever there would be a scenario in which there is a drop in the intensity of light below a set level, a pair of projectors — one for each eye — will flood the user’s eyes in red colour light.

The patent reads that the effect can be considered quite similar to that of photography dark rooms or the airline pilots worn red-tinted glasses. Dark environments with a tinge of red make the rod cells, which act as photoreceptors in the human eye, to immediately come into action and send high contrast images to the brain.

Similarly, when a user enters an envious which is low-light, the projector then automatically come into action and projects a low-level red light in to each eye of the user.

When the shining red light directly enters the human eye, it ends up creating the same response rods as casting a red light would have onto an environment. Which means the rod cells are tricked into sending higher contrast images to the brain.

The patent filed by IBM also contained an important health issue warning issued by the tech company. According to IBM, the users of current glasses such as Google Glass are at a risk of developing a phenomena referred to as binocular rivalry and phoria, which results in a latent deviation or misalignment of the human eyes that appears when both eyes are no longer looking at the same object.
