Researchers Introduce Smart Eye Glasses That Showcase Auto-Focusing Lenses

New invention always surprises people and enhances the hunger for knowledge.  Recently a team of researchers has invented a pair of smart glasses that can automatically recognize the focus of the wearer. That means these glasses can focus on what the user is actually looking at.

According to Mail One, the smart glasses are equipped with liquid-based lenses and sensors. Users can see the nearby or the faraway objects with these glasses. It is not necessary to swap the frame while watching any objects.

Previously a prototype of theses smart glasses was unveiled by a team at the University of Utah. Mastrangelo, a Professor of the Utah Science Technology and Research economic development initiative, says that most of the times people who use reading glasses have to switch them with prescription glasses.  It is truly a boring work.  

Now with the invention of these new glasses, people don't have to change their glasses anymore. Only one pair of smart glasses can perform all necessary works. Professor Mastrangelo and his colleague Nazmul Hasan together designed the unique lenses of these glasses.

The lenses of these smart glasses are equipped with special rubbery membranes. The membranes are actually made of glycerine. Glycerine is a very known liquid product, which is used in the skin care products and soaps.

Each lens of the smart glasses contains three actuators that help the membranes to fit properly. The mechanism is similar to a piston in a vehicle. Actually, this mechanism works as the key process to adjust the focal length between the eye and the lens.  

Mastrangelo, the Professor of USTAR, says that they have to change the membrane shape to avail the accurate optical power. These changes were very necessary because the shape of the lens can provide the proper focal length of the glasses.  Even the frame of the smart glasses is equipped with electronics, and the power of the actuators is controlled by a battery.  

Apart from these features, the researchers also created a technology with the pulses of the infrared light to measure the distance between an object and the glasses. It is actually a distance meter that works to measure the distance. When a user of these smart glasses looks at an object, then the meter quickly measures the distance and advises the actuators to curve the lenses accurately.

Nazmul Hasan reveals that the lenses of these smart glasses can change the focus from one object to another one in just 14 milliseconds. Even the battery can last more than 24 hours per charge. That means the battery in the frame is a rechargeable battery.  

One more surprising fact of this new pair of smart glasses is users have to plug-in their eyeglasses prescription into an app that ultimately calibrates the lenses via a Bluetooth connection. This process is necessary to activate the glasses. Now it is time to see when this unique device will be available for the people.
