EnChroma Lenses for Color Deficiency

Color “blindness” is more accurately referred to as Color Vision Deficiency (CVD). This condition has been recognized for centuries, but for the first time, advanced technology from EnChroma makes it possible to experience the full vibrancy of color.

EnChroma lenses are specially designed to separate wavelengths of light, filtering out specific colors that might otherwise be misinterpreted by the brain. For individuals with color deficiency, this allows their brain to “fill in” the missing information, providing a more accurate perception of the color spectrum.

How Do EnChroma Lenses Work?

Normally, the human eye has three types of receptors (cones) responsible for color perception: red, green, and blue. However, individuals with color deficiency—particularly red-green deficiency, the most common type—may have overlapping responses in their cones. This can result in difficulty distinguishing between certain shades.

EnChroma lenses work by selectively filtering light wavelengths, allowing the brain to better differentiate colors. This cutting-edge technology is helping millions of people experience a richer, more vibrant world.

How Common Is Color Deficiency?

Approximately 1 in 12 men and 1 in 200 women experience some form of color deficiency.
Of those with CVD, about 4 out of 5 cases fall under the category of anomalous trichromacy (a milder form of deficiency), which EnChroma lenses can address effectively.

What Is Color Vision Deficiency?

Color deficiency occurs when the cones in the retina respond to light differently than normal. People with color deficiency can still see colors but may confuse certain shades or fail to distinguish between similar hues.

For example:

Red and green might appear nearly identical.
Certain blues and purples may look the same.

This can impact daily life in subtle yet significant ways, from identifying traffic signals to choosing clothes or recognizing the colors in art and nature.

Experience Color Like Never Before

EnChroma lenses are a breakthrough for individuals with color deficiency. By helping the brain accurately process light wavelengths, these lenses unlock the ability to see color in its truest form.

TYPES OF COLOR DEFICIENCIES

Deutan Color Deficiency

Deutan color deficiency (also known as deuteranomaly) is a type of red-green color deficiency in which the green cones in the eye detect too much red light and not enough green light.

As a result red, yellow, green, and brown can appear similar, especially in low light. It may also be difficult to tell the difference between blues and purples, or pinks and grays. Learn more about Deutan and other types of color deficiency.

Protan Color Deficiency

Protans are people with protanomaly, a type of red-green color deficiency in which the red cones do not detect enough red and are too sensitive to greens, yellows, and oranges.

As a result, greens, yellows, oranges, reds, and browns may appear similar, especially in low light. It can also be difficult to tell the difference between blues and purples, or pinks and grays. Red and black might be hard to tell apart, especially when red text is against a black background. Learn more about Protan and other types of color deficiency.

Tritan Color Deficiency

Tritan-type color vision deficiency is characterized by a loss of color discrimination for shades of blue and yellow but it is not a typical form of color deficiency.

This can be caused by age-related factors, genetic factors, as well as exposure to certain toxins such as mercury. A complete diagnosis of color vision deficiency is not possible using online testing–consult an eye care professional for more information.
