Called Autofocals, this innovative pair of glasses developed by researchers at Stanford University automatically track your eyes and focus on the desired object. This is a great alternative to those who do not want to get laser eye surgery, especially since the ability to refocus at near distances worsens as the lenses in our eyes stiffen beginning around age 45. There’s no word yet on when this will become commercially available, but it could mean ditching the reading glasses, progressive lenses or monovision glasses.

How do they work? Think of them as artificial eye lenses, as in these glasses are filled with fluid that expand and contract as your field of vision shifts, while eye-tracking sensors determine what is being viewed. Since most of the technology already existed (lenses + trackers), the researchers only had to make custom software that analyzes the eye-tracking data to ensure focal accuracy.
