A visual aid device is proposed that enhances or restores peripheral vision. The device, which consists, among other parts, of optical elements, may take the form of eyeglasses, or may be placed in contact with the eye, or may be implanted in the eye. This device may be useful to persons with a partial or complete loss of peripheral vision due to ailments, or to persons who wish to extend their field of natural vision. The essential novel idea of the device is the stratagem to project the scenery to be viewed on a smaller area of the retina than the area on which the scenery is projected without the use of the device. This smaller area is chosen to be that area which is capable of perceiving the image.
