For the Blind, an Actual-Reality Headset

The eSight 3—which weighs less than a quarter of a pound and is operated by hand-held remote—captures the world through a camera system and then displays it on OLED screens that sit very close to the eyes. Legally blind people have some limited vision, and eSight’s displays are tuned to make use of it. By dialing up contrast and allowing users to zoom in, it can dramatically amplify sight without a surgical procedure.
