Letter Contrast

Contrast Sensitivity Functionality (CSF) is a critical part of vision. Unlike visual acuity measurements, contrast testing provides significant information in relation to a patient’s visual function. Information that may overlooked by simply conducting visual acuity test. Evidence suggests that contrast testing results is an indicator of real world performance; simply measuring 20/20 vision does…
