Color Vision Testing

The Farnsworth-Munsell 100 Hue and the Farnsworth Munsell D-15 tests consist of colored caps that the patient arranges in the correct color order under controlled lighting conditions.

The D-15 test is used to screen dichromatic type defects while the 100 Hue gives more complete information of discrimination ability around the color chart.

Each eye is tested individually with the use of an eye patch and gloves are worn to protect the sensitive color chips. The patient arranges the colored chips as quickly as possible in the order that seems correct to them. The test administrator will supervise and then record the chip arrangements. The order of the chips will access if a patient has any color deficiencies.

The color vision testing report typically takes about two weeks to be dictated by a physician.
