Patent attributes
A visual impairment device includes a light source, a modulator, and a controller. The light source capable of generating two or more high intensity light beams having different peak wavelengths, wherein at least one of the light beams has a wavelength bandwidth of less than 100 nm. The modulator modulates the two or more beams of intense light to produce a spatial array comprising a first array of first light beams having a first peak wavelength and a second array of second light beams having a second peak wavelength different from the first wavelength. The controller includes control circuitry for controlling the light source, the modulator, or both. The spatial array is projected into a space such that a lateral distance of at least one first light beam to a second light beam is in a range of 40-110 mm within at least one area of the space.
