Abstract (in Japanese) (See Japanese page) 
(in English) Lens of the human eye, cloudiness is increased with the age. It is called cataract in severe cases. Cloudiness of the lens causes a reduction in visual acuity in low light and affects the glare to the light source. As a result, when different in cloudiness subject to the readability evaluation of presented display the same content, there is a case in which evaluation is different. In this study, it was evaluated experiments on readability of three types of device (e-paper, LCD and paper). Subjects were 98 patients (18-86 years of age). Using the VAS (Visual Analogue Scale) to evaluate, illuminance was set 14 stages. In the light-emitting display, under low illuminance, high cloudiness of the subjects of readability evaluation was significantly lower than the subjects of low cloudiness. In non-emissive displays and paper, under high illuminance, readability evaluation of medium cloudiness subjects were slightly higher evaluation than the subject of low cloudiness.
