- W4200392712 abstract "In this study, the resolution function of the eye vision system were measured by optical grating eye charts with different spatial frequencies and contrasts, and the optical measurement technology of contrast sensitivity function was established. In general, the visual acuity of the macula of the subject is tested with high contrast eye charts, which cannot objectively obtain the real response of the subject to the contrast sensitivity of the gradient black and white and the detail part of the object. Contrast sensitivity examination plays an important role in the early diagnosis of eye diseases and disease tracking. In this experiment, six elderly subjects with visual acuity 1.0 were selected for testing, and it was found that the contrast sensitivity test values of the subjects were low in the low, medium and high frequency areas of the inverted U zone." @default.
