Abstract:
1. A synthetic resin lens wherein a thermoplastic resin is caused to contain a blue pigment having the lowest value for light transmittance in 570 to 610 nm and a pink pigment, among blue light of 380 to 500 nm, having the highest value for light transmittance in 400 to 440 nm and the lowest value for light transmittance in 480 to 520 nm, wherein a content rate of the blue pigment is 0.004 to 0.005 wt % and a content rate of the pink pigment is 0.008 to 0.009 wt % either resulting in a transparent achromatic lens having the lowest value for light transmittance in 570 to 610 nm or resulting in a sheet having the lowest value for light transmittance in 570 to 610 nm and the sheet is attached to a transparent thermoplastic resin lens.
