Abstract

A summary of the invention, which appears on the classifieds page ReadFile:DEPCT63. Current invention is related to the improved color reproduction of opticalglass, in particular spectaclelens, which are composed of glass materials that In this case, the fabrication-based method includes: determination of the material-specific intrinsiccoloration of the given glass material; Glass thickness at multiple evaluation points on optical glass; identification of intrinsic color of optical glass from material specific intrinsic color of a given glass material and glass thickness at multiple appraisal points on optical glass. Determination of the reference colorpigment for at least one colorpigment so that the reference pigment when used with a reference substrate will produce a meaningful color on optical glass. For this reference substrate; a colorcorrectionmodel describing the relationship between the deviation of the pigment content. for at least one pigment from the reference pigment content of at least one pigment and the resulting color deviation of the substrate referring to the target color; and the target pigment determination. deviating from the reference pigment content by the color correction value which compensates for the specified intrinsic color of optical glass according to the established color correction model--------- ----------------------------------------------------
