An Introduction to Contrast Sensitivity Testing

  • Jeremy M. Wolfe


In the treatment of visual disorders and eye disease, it is obviously useful to assess the patient’s visual abilities. In principle, a great number of abilities could be tested (e.g., perception of motion, depth, color, faces, etc.). In practice, however, the first and often the only aspect of vision to be tested is spatial vision in or near the fovea. As used here, the term spatial vision refers to the ability to see achromatic, two-dimensional patterns. The most common clinical measures of spatial vision are visual acuity measures. In recent years there has been increasing awareness of the limitations of acuity measures and a corresponding rise in interest in other measures of visual function, in particular, contrast sensitivity.
