eSight are wearable electronic glasses that allow the legally blind to actually see. It is FDA approved.
eSight can autofocus on short, medium and long-range objects. Interestingly, eSight’s many unique features—such as 14-times zoom, image contrast enhancement, reverse color display, etc.—enable eSight users to actually see many things that normally-sighted people cannot see.
The most common causes of vision loss among current eSight addresses include:
Leber’s Hereditary Optic Neuropathy
Some forms of Glaucoma, Retinitis Pigmentosa
It is very expensive. eSight costs $15,000.
However, eSight fully recognizes that many of the legally blind cannot afford to pay this price and will do all it can with sponsors and funding organizations to ensure that anyone who needs eSight will get the glasses regardless of their ability to pay.
