Color vision testing is important for many careers such as pilots, welders, electricians, and many others. Some professions require color testing prior to a job offer being provided.

We have the capability of providing color vision testing to meet most employment requirements for patients with the Hardy-Rand-Rittler (equivalent to Ishihara) and Dvorine. If a patient is unable to pass one of the two pseudoiscochromatic plate tests, we also offer a less common color test known as the Farnsworth D-15.

The Farnsworth D-15 is a less common test that requires patients to put “test caps” in order of next closest color starting with the first reference cap to the best of their ability. Once completed, the test is scored and if graded as a failure, the test can be repeated a second time.

Some patients with mild color deficiencies will fail the HRR, Ishihara, or Dvorine test but then are able to pass the Farnsworth D-15 and still have adequate color vision for their jobs.

Unfortunately the Federal Aviation Administration does not recognize the D-15 as an acceptable test, but the HRR and Dvorine are both accepted.

If you are in need of color vision testing, please let our staff know when you are making your appointment that you will need a specific test. If you have paperwork that needs to be filled out, please bring it with you or instructions that would assist with providing reports if needed.
