Color Blindness Treatment in Johns Creek, GA
The majority of us perceive the world around us in color. For some, however, the ability to see colors in a normal way may be inhibited or prevented entirely, causing difficulty or a complete inability to distinguish between colors. These instances we refer to as color vision deficiency, or colloquially, color blindness. Patients with color blindness will typically present with one of the two color blindness symptoms:
- You have difficulty seeing colors and the brightness of colors in a usual way
- You have an inability to distinguish between shades of the same or similar colors, particularly red and green, or blue and yellow
In rare, severe color blindness instances, patients will not be able to see color at all, experiencing the world around them in black, white and gray. It is important to discuss color blindness with a healthcare provider, who can identify whether your color blindness is genetic or caused by an underlying health concern that warrants addressing.

Color Blindness Causes
Our ability to see takes place as light enters the cornea and the lens focuses it onto the retina, the thin layer of tissue at the back of the eye that contains millions of light-sensitive stems called photoreceptors. Shaped like rods and cones, these differing photoreceptors contain photopigment molecules which chemically change as they absorb light, triggering electrical signals that are passed from the retina to the visual components of the brain. The cones contain one of three photopigments which make them sensitive to long (red), medium (green), or short (blue) wavelengths of light. The presence of these three types of photopigments, each sensitive to a different part of the visual spectrum, facilitates our rich color vision. Then what causes color blindness? Commonly, color blindness is inherited, while in some cases acquired color blindness may occur as the result of a health condition, such as age-related macular degeneration (AMD) , optic neuritis, sarcoidosis, glaucoma , diabetic retinopathy or cataracts.
In most cases, however, color blindness is genetic and results from defects in the genes that contain instructions for making the photopigments found in cones. Some of these defects lead to a complete loss of a photopigment (known as complete color blindness), preventing you from being able to see any color whatsoever, while other defects may cause you to be more sensitive to some colors than others (hence causing partial color blindness). There are, thus, varying extents of color blindness.
Types of Color Blindness
There are different kinds of color blindness. You may have red-green, blue-yellow or complete color blindness. These broad categories are broken down more specifically into different subsets of color blindness.
Red-Green Color Blindness
- Protanomaly: Affecting males, protanomaly is a mild form of color blindness causing the red cone photopigment to be abnormal, resulting in red, orange and yellow to appear greener and other colors to appear less bright.
- Protanopia: Affecting males, protanopia occurs when there are no working red cone cells, causing the color red to appear black, while certain shades of orange, yellow and green appear yellow.
- Deuteranomaly: The most common color blindness, affecting males, deuteranomaly occurs when the green cone photopigment is abnormal, causing yellow and green to appear redder while violet and blue are hard to discern.
- Deuteranopia: Affecting males, deuteranopia occurs as the result of the green cone cells not functioning, and causes red to appear brownish-yellow and green to appear beige.
Blue-Yellow Color Blindness
- Tritanomaly: A rare form of color blindness which affects males and females equally, tritanomaly-affected people have functionally-limited blue cell cones, causing blue to appear greener, while it can become difficult to distinguish yellow and red from pink.
- Tritanopia: An extremely rare form of color blindness affecting males and females equally, tritanopia (also known as blue-yellow color blindness) causes there to be a lack of blue cone cells. This results in blue to appear green, while yellow will appear violet or light gray.
Complete Color Blindness
- Cone monochromacy: A rare form of color blindness, cone monochromacy occurs when two or three cone cell photopigments fail to work.
- Rod monochromacy or achromatopsia: A rare, and the severest, form of color blindness, this form of monochromacy occurs due to none of the photopigments functioning, causing its afflicted to see in black, white and gray.
Color Blindness Treatment
A color blindness diagnosis is straightforward. Your healthcare provider will conduct a color blindness test to determine whether you have color blindness, which consists of a number of patterns made up of multi-colored dots. If you do not have color deficiency, you'll be able to identify numbers and shapes among these dots, while a color blindness-afflicted patient will have trouble seeing these shapes (or not be able to see them at all). There is no cure for color blindness, though in most cases color blindness doesn't cause a significant disability. If you suffer a severe form of color blindness, it is important to meet a healthcare provider who can discuss strategies to live with your condition.
If you suffer an acquired form of color blindness, on the other hand, you'll want to meet with your healthcare provider to address the underlying condition causing your color blindness. Most people who acquire color blindness are able to retain some ability to perceive all colors following treatment; however, the extent of restored vision varies widely by condition and decreases if treatment is not sought.
