Hi-Tech Vision-Correcting Gadgets

Before getting a little ahead of oneself, the smart contact lens isn't something out of some sort of sci-fi flick that enables people to have enhanced vision or instant information. Nevertheless, its capabilities are still impresses. It is meant for diabetes patients to help them keep track of their glucose levels. The smart contact lens is embedded with a mini wireless chip and glucose monitor that measures the glucose levels of the wearer's tears.

Developed by Google X, the smart contact lens is being touted as a less painful way of tracking such vital information than pricking one's finger. Since it will be able to conduct readings on a per second basis, it is purported as an early warning device for when glucose levels begin to drop. It is still a work-in-progress.
