摘要:
A molded optical filter is provided having effective filtering of energy emissions at an optical density (OD) of greater than 4 in three energy emission bands corresponding to the wavelengths of laser emissions while preserving the wearer's ability to differentiate and recognize colors and having a pleasing overall color. The selective optical filter is a moldable polymer filter that has three dyes therein to produce sharp notch filtering ranges at about 530 nm, 700 nm and 1060 nm and a fourth color balance dye therein to adjust the overall color of the filter making it more pleasing and desirable to the wearer.
