Farnsworth D15

Book Appointment

The Farnsworth D15 is an in depth test to detect colour vision deficiencies.

The test includes different discs of colours which you will be asked to arrange in the correct order. Those with colour deficiencies will have difficulties arranging these discs and make mistakes. These mistakes are recorded on a score sheet template. Based on the results of the final vector diagram, the type and severity of the colourblindness can be determined.

The D-15 colour test can help differentiate between protan, deutan and tritan colour vision deficiencies as well as their severity. Some professions will require this test to be completed as part of their entrance requirements. 

The Farnsworth D15 test is available at Perception Eyecare. Call our office today to learn more about it or to book an appointment at 289-309-1090
