I'm not sure if there is any device or product around that just replaces human eye with digital smart camera. What I mean is Smart Eye Device can do?

Wearable Smart Eye Device WSED Features:

• Identity obstacles , identify people around while walking. 
• Look for traffic light  any object to assist visually challenged person to move around with ease like normal eye can. Assistive and adaptive vision to make a clear mapping of path for visually challenged. 360 eye vision smart device for safety.
•  Read image, text and recognize any people and object. Just like any eye.

Just imagine if automated car can  manoeuvre then on similar line we can think of solution to replace eye with smart eye.
