Abstract
The ability to distinguish contrast plays an important role in patients' everyday vision. Contrast sensitivity testing can identify many ocular diseases. Testing the peak of contrast sensitivity function provides a useful clinical adjunct to standard visual acuity assessments. This article reviews the basics of contrast sensitivity. It also describes the currently available contrast sensitivity tests and compares their reliability, advantages, and disadvantages. Drs. Spaeth and Richman have developed and patented a contrast sensitivity test titled the Spaeth/Richman Contrast Sensitivity test. Dr. Wirostko has no financial or proprietary interest in any material or method mentioned.Keywords
