Color blindness doesn’t have to be a vision condition you just endure. Today’s optometrists can offer you options that address the color deficiency you deal with. While complete color blindness, leaving a person with only monochromatic vision, is extremely rare, the more color specific kinds of color blindness are less uncommon. The more specific forms of color vision deficiencies are generally characterized by a muting in a certain color, or sometimes in how a rage of color perception will narrow.

A person with a normal range of color vision has what optometrists refer to as broad spectrum color perception. This includes not just the primary red and yellow and blue colors, but also intermediate colors such as orange, green, and purples. The human eye normally can perceive a wide variety of graduations in color hue that run the spectrum.

Patients with deuternomalia have a subdued color perception. When they view colors, the brightness of colors that makes them pop for most people is reduced; as if they were viewing those colors drawn in chalk rather than ink. Another common type of color vision deficiency is protanopia, which is colloquially known as red-green color blindness. Tritanopia leaves a patient seeing all colors as if they were being filtered through a pink or green lens.

Anyone who has noticed a color perception deficiency should consult their optometrist, and learn how the condition might be improved.

Key Points:

  • 1Normal color vision means that people can clearly discern between different colors. That includes a broad spectrum of colors that people need to see.
  • 2It helps to differentiate between subtle variations of hues on the color spectrum. Vision deficiency is one of the leading concerns about vision loss overall.
  • 3Eye doctors are working to see some of the differences in vision among patients. The research has directed them to use modern techniques when it comes to proper care.

Normal color vision is characterized by the ability to clearly discern vivid color across a broad spectrum (all the colors of the rainbow – red, orange, yellow, green, blue, indigo, and violet) and to differentiate subtle variations of hue.
