Abstract
The invention generally relates to optical filters that selectively attenuate the transmission of visible light for the purpose of enhancing or transforming the quality of human vision; to improved designs of such optical filters that provide an improved quality of color vision or of color perception; to methods of using such improved optical filters to enhance human vision during outdoor night time viewing conditions; to methods of using such improved optical filters to reduce the stimulation of the intrinsically photosensitive retinal ganglion cells (ipRGCs); to methods of using such improved optical filters to reduce the discomfort of glare; and to methods of using such improved optical filters to mitigate the symptoms of low vision or age-related visual impairments including for methods of treating or slowing the progression of persons with cone dystrophy including for persons with retinitis pigmentosa.
