Abstract

Okulary do wspomagania widzenia barw składają się z zauszników (1), ramki montażowej (2), wymiennych filtrów optycznych (3) montowanych w ramkach montażowych (2) oraz wymiennego układu podświetlania (4), który składa się licząc od strony użytkownika z zasilania (4c), źródła światła LED umieszczonego nad filtrem oraz filtru modyfikacji rozkładu widmowego i zamocowany jest do oprawy okularowej nad ramkami montażowymi (2) wymiennych filtrów optycznych (3). Wymienne filtry optyczne o rozkładzie widmowym natężenia należą do trzech grup i tak dla grupy pierwszej najwyższe wartości przepuszczania występują dla przedziału długości fal od wartości około 380 nm (początek zakresu promieniowania widzialnego) i do około 530 nm (maksimum względnej czułości widmowej dla czopków M), dla grupy drugiej najwyższe wartości przepuszczania występują dla przedziału długości fal do około i 440 nm (maksimum względnej czułości widmowej dla czopków S) do około 530 nm (maksimum względnej czułości widmowej dla czopków M), a dla grupy trzeciej przepuszczanie rośnie w przedziale do wartości około λ=560 nm (maksimum względnej czułości widmowej dla czopków L) do 780 nm (koniec zakresu promieniowania widzialnego). Filtr modyfikacji rozkładu widmowego jest filtrem, dla którego maksimum występuje dla długości fal λ=440 nm, λ=530 nm lub λ=560 nm.Color vision glasses consist of temples (1), mounting frame (2), replaceable optical filters (3) mounted in mounting frames (2) and a replaceable backlight system (4), which consists of a power supply from the user's side ( 4c), the LED light source placed above the filter and the spectral distribution modification filter, and is attached to the eyeglass frame above the mounting frames (2) of replaceable optical filters (3). Replaceable optical filters with spectral intensity distribution belong to three groups, and for the first group the highest transmission values occur for the wavelength range from approximately 380 nm (beginning of the visible radiation range) to approximately 530 nm (maximum of relative spectral sensitivity for M cones), for the second group, the highest transmittance values occur in the range of wavelengths up to approximately i 440 nm (maximum of relative spectral sensitivity for S cones) to approximately 530 nm (maximum of relative spectral sensitivity for M cones), and for the third group the transmittance increases in the range up to approximately λ=560 nm (maximum of relative spectral sensitivity for L cones) to 780 nm (end of the visible radiation range). The spectral distribution modification filter is a filter for which the maximum occurs at wavelengths λ = 440 nm, λ = 530 nm or λ = 560 nm.
