This product is not intended to diagnose, treat, cure, or prevent any disease. This test is not a medical diagnosis and has not been evaluated by the FDA. Tritans typically confuse shades of yellow versus gray and blue versus gray.Д¬VD is classified by type (protan, deutan or tritan) as well as the extent which can be mild, moderate or strong. Tritans have a blue-yellow color vision deficiency caused by an anomaly of the blue-sensitive retinal cone cells. Deutans typically confuse shades of yellow versus green, green versus gray and magenta (or 'pink') versus gray. Protans typically confuse between orange versus green, red versus black, blue versus purple, and light red (or 'salmon') versus gray.Дeutans have a red-green color vision deficiency caused by an anomaly in the green-sensitive retinal cone cells. Protans have a red-green color vision deficiency caused by an anomaly in the red-sensitive retinal cone cells. An estimated 3-4% of the population has acquired blue-yellow CVD associated with an age-related low-vision disorder. Someone who is color blind is technically not 'blind' to colors, but may misidentify, confuse, fail to notice or notice colors less quickly than normal.ДЄbout 1 in 12 male and 1 in 200 females worldwide have congenital red-green color vision deficiency (CVD).

Tap or click the button corresponding to which shape you see. Look for a shape, such as a number or symbol, which is embedded within the dot pattern.

You will see a series of images composed of dots with varying size and lightness. Depending on which colors are seen, the type and extent of color vision deficiency can be estimated. When a person has color blindness, they are able to see some colors better than others. By testing with different colors we are able to understand which colors you may have difficulty seeing. This test measures your ability to see a pattern based on its color.
