The experiment objects are 15 age-related cataract patients (28 target eyes). Furthermore, this study makes an Age-related Cataract Image Blurring Program which can blur the digital eye chart for the second experiment -"Blurry Image Recognition Experiment". The purpose of the second experiment is to decrease the visual acuity of young healthy eyes (vision with correction, 1.0) and to gather statistics for recognition critical point. These statistics represent different blurry degree of visual degeneration and are used to construct the simulation function of testbed.
