Star Trek-like headset lets woman who lost her sight as a ch
The eSight 3 uses a high-speed HD camera and two displays to allow users with vision issues to better see the world around them. Yvonne Felix, who lost her sight as a child due to Stargardt disease, a juvenile form of macular degeneration, tried the new device.

A high-speed HD camera and two OLED displays allow video to be filmed and processed in real-time, enhancing both contrast and quality.This allows users with vision issues to see the world around them in more clarity.The eSight 3 is light and portable and has around six hours of battery life.But creating such a device was no mean feat.
eSight had several technical challenges to overcome when making the headset.Low-latency was key, ensuring the viewer could see the world in as close to real-time as possible.

And maximising peripheral vision was also important to make sure users did not feel ill or lose balance – as is often the case with virtual reality headsets.The device can also auto-focus, allowing users to transition between objects nearby and far away.While this offers a real solution for people with vision issues, the device is not cheap, and costs $10,000 (£8,000).
