| Outline of Final Research Achievements |
In this study, in order to examine the objective selection index of absorptive glasses, which are visual aids, we focused on the color perception when wearing the glasses. Because it is difficult to evaluate with commercially available absorptive glasses, we made systematically set to evaluate the cone stimulation ratio and visual transmittance, the visual transmittance is 20% to 80%, and the cone stimulation ratio (L, M, S) = (1:1:1) to (1:0.5:0), which consists of 12 types of filters. We tried to measure young and elderly people, assuming the indoor and outdoor environment, but due to the influence of the Corona disaster, only some measurements can be carried out for young people. After all, we only confirmed the decline trend of color discriminability and categorization characteristics due to the decrease in the S-cone stimulus ratio.

| Academic Significance and Societal Importance of the Research Achievements |
錐体刺刺激量比と視感透過率を系統的に設定できるフィルターは，特に市販もされておらず，それを作成できたことは，本研究の一番大きな成果と言える．このことにより，錐体刺刺激量比と視感透過率を系統的に設定し評価することが可能となった．さらに若年者におけるS錐体刺激量比の低下に伴う，色弁別と色分類特性の低下傾向を若年者で確認した．今後，さらに測定を行うことにより，遮光眼鏡の客観的な選択指標に錐体刺激量比が使用できる可能性を示すものである．現在でも，遮光眼鏡の選択は患者の主観的な見え方の判断で行われる傾向が強く，客観的評価の糸口を掴んだことも本研究の成果と言える．
