Abstract
Description
本実施形態に用いる着色剤は、ヨウ素、直接染料、反応染料、酸性染料などを使用することができる。
前述したように製造された着色レンズについて、分光透過率計を用いて分光透過率を測定し、UCS色空間における色の座標値L、a、bを定めた。なお、UCS色空間における色の座標値Lは0〜100に区分された明度である。値L、a、bを、CIE標準表色系における三刺激値X、Y、Zで示せば、L=100Y1/2、a=175(1.02X−Y)Y-1/2、b=70(Y−0.847Z)Y-1/2である。
次に、着色レンズの色識別の評価結果について説明する。
Claims (1)
- UCS色空間における色の座標値L、a、bによって規定する着色レンズの設計方法であって、
値Lによって決まるab平面上において、L=87.4でa=+0.35かつb=+3.0、L=74.2でa=−0.25かつb=+1.6、L=49.9でa=+1.5かつb=+3.35をそれぞれ目標値として選択し、
L=87.4で−4.3≦a≦+5かつ−3≦b≦+9、L=74.2で−3.5≦a≦+3かつ−5≦b≦+8.2、L=49.9で−1.5≦a≦+4.5かつ−0.5≦b≦+7.2をそれぞれ偏差範囲として設定し、
さらに、UCS色空間において、L=87.4、L=74.2、L=49.9における前記偏差範囲の頂点を2次多項式の近似曲線で結んで許容範囲を形成し、
UCS色空間における前記許容範囲に含まれるように着色レンズのL、a、bの値を選択する方法。
