Coating materials for preventing photosensitivity and cataracts, light transmitting materials, windows and lighting fixtures

Abstract

Light-transmitting material with filter properties to provide an environment suited to the visual characteristics of the user In addition, it is possible to provide a filter having filter characteristics that take into account the characteristics of human cone cells. It is possible to provide a light transmitting material. The light transmitting material is a light transmitting material coated with a coating agent having a predetermined filter characteristic. A filter material, the predetermined filter characteristics being a transmittance of 60% in the range of 400 to 480 nm. and a relationship between the predetermined filter characteristic and the absorption spectrum of human blue cone cells of 40 The convolution integral in the wavelength range of 0 to 480 nm is the standard filter characteristic with a transmittance of 100%. The characteristic of being cut by 40% or more from the convolution integral of the relevant absorption spectrum in the relevant wavelength band. It is sexuality.
