A company called Deep Optics is working on new high-tech eye glasses that can change their focus in real-time, depending on distance and type of object.

According to Popular Mechanics, “The Deep Optics lenses work by incorporating a layer of transparent liquid crystal that can be changed by an electric current. The liquid can adjust the refractive index of the lens—the way it bends light passing through—to effectively change the prescription of the glasses according to the distance of the object your eyes are focusing on.”

There are sensors in the glasses that track the pupils as the distance between the person and object changes. “A processing unit built into the glasses can use the pupillary distance to calculate exactly how far the user is from the object, and the correct electrical current alters the liquid-crystal layer to provide the perfect prescription in real time.”

As we become more efficient, dynamic, and diverse human-beings, we have the responsibility to understand the present and future potential of these hidden forces all around us.
