Contrast Sensitivity tests can be used for many different applications. One of these is monitoring vision/ ocular therapy. By using contrast sensitivity testing during therapy, doctors can test many facets of vision, not just acuity. Also, by testing contrast sensitivity, doctors can get a better idea of everyday life scenarios that the patient is having. This can lead to more accurate and directed therapy and better outcomes.
