Spectrally sculpted multiple narrowband filtration for improved human vision

Abstract

Enhanced visual acuity is provided by one or more exceptionally narrowband absorption dyes having sharp turn-on and cut-off slopes selected to spectrally sculpt light to correct most types of colorblindness, to exaggerate color contrast vision for everyone, and / or to markedly sharpen visual focus beyond normal vision. The dyes are incorporated, for example, in sunglasses, prescription and non-prescription eyewear, window thin films and artificial light sources such as incandescent, fluorescent, and LED lightbulbs to provide improved photopic color vision, improved mesopic dim light color vision, and also sharper scotopic night vision.

Problems solved by technology

[0015] To better understand the prior art Enchroma colorblind laminated film lenses, Figure 8A shows the concept of an interference bandpass "notch filter" described in Patent No. 7,106,509, designed to block 50nm wide blue-green frequency band (470nm-520nm), and a 70nm wide yellow-red band (560-630nm), but it changes color undesirably with the angle of incident light

The net light transmission of Figures 8A and 8B is very low because the prior art filter requires two polarizing films, which absorb (and consume) up to 85% of the incident light (15% net transmission) and are extremely unsuitable for Low light level indoor applications

In addition to the problem of extremely low transmission, where the transmitted wavelength shifts with the angle of incident light, and some other disadvantages including the problem of extremely high cost, these precision laminated optics are Devices are at risk of high thermal stress
