Abstract
The present invention provides a vision assistive device, including: a first reflector, a second reflector and a third reflector. The first reflector is disposed at a first position of a cornea of a human eye. The second reflector is disposed at a second position of the cornea of the human eye. The third reflector is directly disposed in front of the cornea of the human eye. The first reflector and the second reflector are configured to reflect external light such that the external light is focused at the third reflector. Then, the external light is reflected again by the third reflector to the human eye, thereby enhancing a light intensity of the external light received by the human eye.
