Title: METHOD FOR DETERMINING A VALUE QUANTIFYING THE EFFECT OF AN OPTICAL FILTER ON A PARAMETER LINKED TO AN EYE
Abstract:
The invention relates to a method for determining a value quantifying the effect of an optical filter on a parameter linked to an eye, this optical filter blocking at least partially the transmission of light over a predetermined wavelength range, comprising the following steps : a) at least one spectral feature of the optical filter related to the transmittance of this optical filter at at least one wavelength in said predetermined wavelength range is provided, b) the value quantifying the effect of the optical filter on said parameter is calculated as a function of said at least one spectral feature of the optical filter provided in step a).
