How Your Eyes Perceive Light & Colors
You might look at a lush forest and see a vibrant mix of bright greens and rich browns. Someone else looking at that same scene might see a flat wash of dull olive tones. Our team at Total Vision Santa Cruz knows that the difference comes down to how your eyes capture light from your environment.
The main types of colorblindness include red and green deficiency, blue and yellow deficiency, and complete grayscale vision. Your visual experience depends on whether certain light receptors in your eyes function differently than expected. Knowing how these receptors work helps you make sense of your own sight.
The Role of Retinal Cones
The back of your eye contains three types of color-sensitive cones. These tiny structures process red, blue, and green light waves. Color blindness happens when one or more cone types either work incorrectly or aren’t present in the eye.
A typical human eye with three kinds of functioning cones can see up to 1 million different shades of color.
Red And Green Color Vision Deficiency
Red and green deficiency is the most common kind of colorblindness, and it’s far more common in men. This condition affects how you see many natural environments and everyday objects.
Mild Red & Green Vision Changes
People with a mild red-green deficiency may struggle to distinguish red and green.
- Greens and reds may seem to overlap.
- Some of these shades may look less bright than usual.
- Browns, oranges, and greens are easily confused.
Severe Red & Green Vision Changes
In some cases, the eyes are completely unable to perceive either red or green. People with this condition perceive the world as a mixture of what people with normal vision might call a mixture of greens, blues, and some yellows. Pale shades are hard to distinguish, as is the difference between oranges and reds.
Blue & Yellow Color Vision Deficiency
This type of colorblindness is much less common. It happens when the cones that identify blue light don’t work properly or are missing altogether.
Mild Blue & Yellow Vision Changes
A mild change in your blue and yellow perception alters your view of cool and warm tones. These symptoms include the following.
- It becomes hard to tell blue apart from green.
- You confuse yellow hues with red hues.
Severe Blue And Yellow Vision Changes
A significant blue and yellow deficiency happens when the blue-sensitive cones in your eyes are missing altogether. You might experience these symptoms:
- You are unable to differentiate purple from red or blue from green.
- You can’t tell yellow from pink shades.
- Colors look less bright.
Total Color Blindness And Grayscale Vision
Complete color blindness is quite rare. People who have this condition can’t see colors at all, they often struggle to see clearly, and they’re often sensitive to light.
