esight 3: the pair of glasses that enables the blind to see

0

The maker of esight 3, esight, says the glass is for the legally blind. What is legally blind and who qualifies to be called so? Legal blindness is a level of visual impairment that has been defined by law either to limit allowed activities (such as driving) for safety reasons or to determine eligibility for government-funded disability benefits in the form of educational, service, or monetary assistance. It is 20/200.That is someone who cannot see an object 200 feet away unless he/she stands 20 feet from the object. Normal vision should see an object 200 feet away clearly.

The pair of glasses works by recording high­ definition video and uses magnification, contrast and proprietary algorithms to enhance that imagery into something the legally blind can see—enabling them to partake in a variety of activities, including sports, that would otherwise be off-­limits. The glasses is one of the great inventions of 2017.

The company says it has been used by 1000 persons. The glasses costs about $9,995 (#3.5m). Hmmm…the company seems to be saying if you think vision is expensive try blindness!
