Stanford’s Autofocals: Glasses That Track Your Eyes to Focus Automatically

Here is a pair of glasses developed by Stanford researchers that can restore proper vision in people who need progressive lenses. Stanford’s Autofocals rely on eye-tracking technology to automatically control a pair of autofocus lenses to track what the eyes are looking at:

The Stanford prototype works much like the lens of the eye, with fluid-filled lenses that bulge and thin as the field of vision changes. It also includes eye-tracking sensors that triangulate where a person is looking and determine the precise distance to the object of interest.

The team didn’t develop the eye trackers or lenses but they developed the software to use the eye tracking data to keep the lenses in perfect focus. The next step is to downsize the technology.
