## 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.

## Claims

### Claim 1

A vision assistive device capable of enhancing light receiving, comprising:
a first reflector disposed at a first position of a cornea of a human eye, the first position being located at a right edge of the cornea so that the cornea is on a front reflection side of the first reflector and external light from a back side behind the first reflector passing through the first reflector and the right edge is focused to the human eye, enhanced and amplified partially;
a second reflector disposed at a second position of the cornea of the human eye, the second position being located at a left edge of the cornea so that the cornea is on a front reflection side of the second reflector and external light from a back side behind the second reflector passing through the second reflector and the left edge is focused to the human eye, enhanced and amplified partially; and
a third reflector disposed directly in front of the cornea of the human eye;
wherein the first reflector and the second reflector are configured to reflect external light such that the reflected external light is focused at the third reflector; and
wherein the reflected external light is reflected again to the human eye by the third reflector, thereby enhancing a light intensity of the external light received by the human eye.

### Claim 2 (depends on 1)

The vision assistive device according to claim 1, wherein the first reflector and the second reflector are shaped as a semicircular arc or are configured to have a rectangular shape, respectively.

### Claim 3 (depends on 2)

The vision assistive device according to claim 2, wherein when the first reflector and the second reflector are shaped as the semicircular arc, the first reflector and the second reflector are configured to surround the human eye.

### Claim 4 (depends on 1)

The vision assistive device according to claim 1, wherein the third reflector has a circular shape or a rectangular shape.

### Claim 5 (depends on 1)

The vision assistive device according to claim 1, wherein the first reflector, the second reflector and the third reflector are disposed at the first position, the second position and a front position of the cornea of the human eye respectively by way of hanging via a frame.

### Claim 6 (depends on 5)

The vision assistive device according to claim 5, wherein the frame is implemented as a headwear device.

### Claim 7 (depends on 1)

The vision assistive device according to claim 1, wherein the first reflector and the second reflector are directly disposed on the cornea of the human eye at the first position and the second position.

### Claim 8 (depends on 1)

The vision assistive device according to claim 1, wherein the third reflector is made of a translucent material or a transparent material.

### Claim 9 (depends on 1)

The vision assistive device according to claim 1, wherein the first reflector and the second reflector are made of one of the following materials: an opaque material, a translucent material and a transparent material.
