The invention generally relates to optical filters that provide regulation and/or enhancement of chromatic and luminous aspects of the color appearance of light to human vision, generally to applications of such optical filters, to therapeutic applications of such optical filters, to industrial and safety applications of such optical filters when incorporated, for example, in radiation-protective eyewear, to methods of designing such optical filters, to methods of manufacturing such optical filters, and to designs and methods of incorporating such optical filters into apparatus including, for example, eyewear and illuminants.

Multi-band color vision filters and method by LP-optimization

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.

Spectral glare control eyewear for color blindness and low vision assistance

Optical filters affecting color vision in a desired manner and design method thereof by non-linear optimization

The invention generally relates to devices that demonstrate the function of ophthalmic lenses that modify human color perception and to methods and devices that simulate color vision deficiency or color blindness.

Lighting system for simulating conditions of color deficient vision and demonstrating effectiveness of color-blindness compensating eyewear

A system for hearing assistance devices to assist hearing aid fitting applied to individual differences in hearing impairment. The system is also usable for assisting fitting and use of hearing assistance devices for listeners of music. The method uses a subjective space approach to reduce the dimensionality of the fitting problem and a non-linear regression technology to interpolate among hearing aid parameter settings. This listener-driven method provides not only a technique for preferred aid fitting, but also information on individual differences and the effects of gain compensation on different musical styles.
