How the Smart Glasses Work

The University of Utah’s Science Technology and Research economic initiative have come up with these smart glasses that will automatically focus on what you look at, eliminating the need for bifocals even if you have different eye power prescriptions for distance and close vision.

Since a solid can find it difficult to shift focus the computer engineering professor Carlos Mastrangelo and his student Nazmul Hasan created the glasses out of glycerin which is enclosed in thick rubber like, transparent membranes. The membranes are connected to three actuators that help push the membrane forward and back.

This piston action on the membrane allows the curve of the liquid glycerin lens to be adjusted as required. The lenses are placed in special frames where the bridge contains a distance meter. There is also a set of rechargeable batteries in the frame which can last up to 24 hours once powered. This is a promising science project.

The first working prototype of the rather bulky pair of eye glasses was unveiled in the Consumer Electronics Show in Las Vegas. The biggest advantage of the smart glasses is that the customer will never have to buy another pair of glasses again as the lens can be automatically readjusted by feeding in the new eye prescription in to a smart phone app that connects to the glasses via Bluetooth.
