Headworn Video Devices Are Helping The Visually Impaired To See Better

A Comparison of Two Leading Headworn Devices.

Portable electronic magnifiers have come a long way in the past decade, improving clarity of vision for thousands. A natural development for those who prefer to have their hands free has been the creation of several types of headworn video devices, the leaders in the field being eSight and NuEyes.* These devices are similar in their “smart” technology, but different enough to require diligent decision making.

To help with that, especially since high costs are involved, I have put together a basic comparison chart derived from personal experience with the products and interviews with the companies. I hope this will allow future purchasers to make educated decisions about which would best fit their needs.

*Other devices worth considering are Iris Vision and seeBOOST (from the Dallas Lighthouse for the Blind), both of which are more basic and less expensive than the products compared here.
