Study on Contrast Sensitivity of Different Age Groups

Abstract

In this experiment, the digital Mars contrast sensitivity check tables are used to test the contrast sensitivity value between two genders and three age groups. There was no statistically significant difference in contrast sensitivity between genders (P > 0.05) and between different eyes (P > 0.05). The contrast sensitivity of individuals of different groups was significantly different. The contrast sensitivity values of the left eye, right eye and both eyes increase with the increase of visual acuity.
