Properties of color vision in HSV color system lights in the cataractous vision environment [PDF]
, 2009 本研究では、VDT上のHSV色光に対する応答を、白内障再現ゴーグルを装着した場合とそうでない場合についてそれぞれ測定し比較する実験を実施した。その結果、白内障視環境下では全てのHSV色相において被験者応答値の上昇が見られ、特に青系統（ 210°～270°）における感度低下の度合いが顕著であった。青色光は刺激純度が高いため、水晶体の混濁による短波長領域での分光透過率の低下をより強く受けると考えられる。また、色覚閾では輝度減少率がゴーグルの分光透過率と比較して小さいことから、水晶体核内の物質による光の反射 ...
