How does the test work?

The Mosaic test functions similar to a CAD test. Here, a large square is divided into multiple small squares. Here, you need to identify the small square in each question. The smaller square keeps pulsing, making it easier to find out.

When you click on the correct answer, the same square appears somewhere else in the big square, but this time it gets lighter. With every question, the small symbol keeps getting lighter.

The game comprises 20 levels of red-green, purple-green, and purple-red. In the Tritan version of the Mosaic test, you will witness 20 purple-red levels that eventually approximate the background of the large box with each passing question. It is a very accurate method for determining one's color blindness type and severity.

The subject’s task is to identify the motion of odd small square on a large square background with radiance contrast.

The color vision deficiency of indivudal in measured in SN units (Standard Normal Unit). Everything depends on the outcome, and if it demonstrates a red-green threshold of 3 SN Units, it will imply that you need thrice as strong colour signal than the typical CAD observer.

Color vision deficiency – Biology and Causes

Understanding the Biology of an Eye

The process of us seeing colors across the light spectrum is very complex. The process starts with your eyes' ability to respond to different wavelengths of light, including short, medium, and long.

Light has all three wavelengths; they enter your eye through the cornea and pass through the transparent lens and tissue (vitreous humor) in your eye. It then passed through the wavelength-sensitive cells at your eye's back to the retina's macular area. The cones are sensitive to all three wavelengths; the chemicals in them send the wavelength information via the optic nerve to the brain.

If you have normal vision, your eyes perceive color. But when you are color blinded, your cone lacks wavelength chemicals, and it gets to differentiate between red, green, and blue.

What CAUSES color vision deficiency?


If you work at a place exposed to certain chemicals like carbon disulfide, the chances of getting color blinded increases.

Inherited Disorder

Even though the chances of getting these inherited diseases are higher in males than in females, it does not mean that females are immune to them. The most common color deficiency one faces is red-green and blue-yellow. If your family has color

blindness, the chances are rare you are not getting it all. However, you may face a mild-moderate or severe degree of the disorder.


Some drugs can impair your vision, including those used to treat autoimmune illnesses, high blood pressure, heart disease, infections, and psychological issues.


Color blindness can be caused by certain medical diseases such as sickle cell anemia, Alzheimer's disease, leukemia, persistent alcoholism, etc., that damage optical vision.

Improve your Color Vision

Until now, there are no proper treatments for color deficiency, especially if the condition is inherited. However, if the cause is due to certain medical conditions or eye conditions, then the treatment is possible. Whichever prescription or drugs affecting your vision are discontinued, it can help improve your color vision.

Also, colored filter glasses or colored contact lenses are an excellent choice to enhance your perception of contrast between confusing colors. However, the effect of these lenses is temporary and will not improve your overall vision.
