Scotopic Sensitivity Syndrome (SSS) is a visual perceptual dysfunction affecting primarily reading. The condition can be improved by colored filter (lens or overlay). This paper aimed to find research question about screening, effectiveness of overlays, and prevalence of SSS for obtaining new knowledge of research in Japan. The results were as follows from the preceding study. Firstly, it was found that check sheets was important for screening of SSS, and that it should have a less burden for individual with SSS. Secondly, it was found that although individual had reading difficulties, overlay did not always effective those difficulties. Finlay, it was found that prevalence of SSS in Europe and America was 20% to 38%, and 6% in Japan.
