Embodiment Construction

[0024] Photons from the light source are modulated with video information by an intensity modulator. Scanning the modulated light by the scanner in a first direction and a second direction substantially perpendicular to the first direction creates a photonic grating that is projected by projection optics directly onto the user's retina to produce a perceived image without being perceived by the user Or any intermediate images viewed that are outside the user's eyes. It is desirable to employ an eye tracking system to reposition the scanned grating as the pupil of the eye moves such that the beam of light rays coincides with the entrance pupil of the eye.

[0025] The light source can be monochromatic light or beams of red, green and yellow or blue light that can be scanned as RGB video signals to color photons directly onto the user's eyes.

[0026] Now go to the attached image, as in figure 1 The illustrated virtual retina display (VRD) in accordance with at least some embo...

Abstract

A device, system or method for aiding the vision of a visually impaired individual with a reduced functioning retina is provided which overcomes the problems of the background art by overcoming such reduced and / or uneven retinal functioning. defect.

Description

technical field [0001] The present invention relates to a device, system and method for assisting the vision of a visually impaired individual, and in particular to such a device, system and method for assisting a visually impaired individual with a reduced functioning retina. Background technique [0002] Visually impaired individuals frequently suffer from vision loss due to reduced function of their retinas. This reduced function may be due to damage and / or various disease processes that gradually reduce the function of the retina, resulting in impaired vision over time. One example of such a disease process involves age-related macular degeneration (AMD), the leading cause of blindness in US adults. The macula is the part of the retina that provides sharply focused images and is therefore particularly needed for activities such as reading and driving. [0003] AMD presents another challenge, and this is because AMD affects unevenly on the retina, it primarily affects t...
