Bringing Vibrancy Back Into Your Life

Colour deficiency occurs when colours and shades appear different than usual. Although “colour blindness” is often used to describe people with a colour deficiency, this often is not accurate. Total colour blindness is referred to as achromatopsia, and the condition only affects a very small number of people.

Colour deficiency is more common in males than females, with 1 in 10 males having a colour deficiency. The condition is usually inherited, but also may occur as a side effect of certain eye diseases, trauma, or medication.

What Causes

Colour Deficiency?

In the retina, different types of cells detect light, called rods and cones. Rods are responsible for identifying light and dark and helping you see in low light. 

Cones help to determine different colours, specifically red, green, and blue. The cones send information to the brain to create different colour perception. If one or more of these cones aren’t functioning correctly, colour deficiency occurs.

Types of Colour Deficiency

Different types of colour deficiency exist when different cones in the eye aren’t functioning correctly or pick up on the wrong colours.

The most common type of colour deficiency is a red-green colour deficiency. There are 4 different types of red-green colour deficiency:

  • Deuteranomaly
  • Protanomaly
  • Protanopia
  • Deuteranopia

There are 2 different types of blue-yellow colour deficiency:

  • Tritanomaly
  • Tritanopia

How EnChroma Glasses Can Help

EnChroma glasses work by selectively filtering out specific wavelengths of light that overlap and create confusion between colours. They are uniquely engineered to give those with colour deficiency the ability to see the entire broad spectrum of colour that many of us enjoy.

EnChroma glasses are designed to increase the contrast of red and green colour signals. The glasses were created with an application of science, optics, and mathematics to improve colour vision with various forms of red-green colour deficiency.

Most patients with colour deficiency report positive experiences when wearing EnChroma glasses. We’d be happy to evaluate your eyes to see if your vision can be improved!
