Abstract

The invention relates to a method for designing color filters which improve or modify color vision of the human eye. According to the invention a desired opponent signal function to be attained is divided by a real opponent signal function characteristic of the eye color vision to be improved or modified, the negative range of the resulting function is replaced by zero, the whole function is normalized to give a spectral transmission function, and, if desired, one or more section(s) of this spectral transmission function is modified. The invention also relates to color filter means designed by the above method.

Description

technical field

[0001] The present invention relates to a method for designing color filters that improve or correct human eye color vision. The invention also relates to color filter devices, such as spectacle lenses, contact lenses or intraocular lenses, which may be designed using this method. According to the scheme of the present invention, it can be mainly used to improve the color vision of people with color defects (that is, people with color perversions, usually also called color blindness); however, this scheme is used to correct the color vision of people without color defects. , better results can also be obtained. Background technique

[0002] The color vision of the human eye comes from the stimulation of photoreceptors (also called cones), which are present on the retina and are sensitive to three different wavelength regions, namely long-wave (l), medium-wave (m) and short-wave ( s) area (see Stockman, A., Sharpe, L.T.: "The Spectral Sensitivities of the Mi...
