The Stereo Optical Functional Vision Analyzer® (FVA) is the gold standard clinical and research instrument for evaluating the quality of vision beyond simple visual acuity. The FVA reliably measures the contrast sensitivity function with and without disability glare. This unique instrument therefore provides a full measure of vision assessment, analogous to a full audiogram for hearing function. In addition, the FVA been validated by a number of published clinical papers, and remains the standard in both the eye clinic and pharmacology research laboratory for FDA compliant drug studies. At the Captain James A Lovell Federal Health Care Center, we have used this instrument in several published randomized placebo controlled clinical trials.
