What is the Rabin Cone Contrast Test?
The Rabin Cone Contrast (CCT) is a computerized color vision test that measures the ability to detect ototypes presented in red, green, and blue at varying contrast levels. The test provides a quantitative measurement of cone contrast sensitivity, which can help identify and characterize color vision deficiencies.
​
Multiple clinical trials have shown utility of the Rabin CCT in conditions like glaucoma, macular degeneration, retinal vein occlusion, and congenital color deficiency.

Frequently Asked Questions
1
How is the Rabin test different from other color vision tests?
The Rabin test different from traditional color vision tests because it measures the numerical contrast sensitivity of each individual cone type in the eye—red (L-cone), green (M-cone), and blue (S-cone)—separately and for each eye independently, rather than just using a simple pass/fail or pattern-matching approach. You will receive a score for each cone type per eye
2
How long does the test take?
The test takes about 2 to 3 minutes per eye, or roughly 5 to 10 minutes for both eyes. You should come to your appointment wearing glasses or contact lenses that you already wear to maximize your visual acuity.
How much does the test cost?
The fee for taking the test is $180. Health insurance is not acccepted.
