Color Blindness: Types, Causes, And Diagnosis
Color blindness, or color vision deficiency, affects millions worldwide. It's more common in men than women, and while there's no cure, understanding the condition can help manage its impact. This article will cover everything about color blindness.
What is Color Blindness?
Color blindness isn't actually a form of blindness, but rather a deficiency in how you see colors. If you are color blind, you have trouble distinguishing certain colors, such as blue and yellow or red and green. This happens when the cone cells in the retina are either absent or not functioning correctly. Cone cells are photoreceptors responsible for color vision.
Types of Color Blindness

- Total Color Blindness (Monochromacy): The rarest and most severe form, where individuals can only see shades of gray.
Causes of Color Blindness
Most people are born with color blindness. It's usually inherited, meaning it's passed down through genes from parents to their children. However, color blindness can also develop later in life due to: — Unbelievable Stupidity: You Won't Believe What Happened!

How is Color Blindness Diagnosed?
Diagnosing color blindness is straightforward. An eye doctor uses simple tests to check how well you can see colors. The most common test is the Ishihara color test, which uses a series of colored dot patterns. People with normal color vision will see a number within the dots, while those with color blindness will either see a different number or no number at all. — Michael Loftus' Wife: Everything You Need To Know
