The different types of color blindness are generally divided by whether the vision defect is inherited or acquired. Likewise, normal vision can be referred to as trichromacy.

Individuals who have all three types of cones working at full capacity are called trichromats ( tri meaning three and chroma being the Greek word for color). With just those three light sensitivities, we can see literally thousands of colors. The absence of any of the three types of cones is what accounts for different types of color blindness.

S-cones (short-wavelength absorbing cones) help us see blue, M-cones (medium-wavelength absorbing cones) reveal green and L-cones (long-wavelength cones) interpret red light. The human eye contains three different types of cones. All types of color blindness have to do with diminished (or absent) functionality in the cones. The human eye has eighteen times more rods than cones.īut the cones are what give us fine detail and color. They are the reason your eyes will adjust in a dark room, allowing you to see basic shapes. Named after their shapes, they are called rods and cones. Our eyeballs have two kinds of photoreceptors in the retina that are designed to absorb light. To understand the multiple types of color blindness that exist, it can be helpful to briefly review the basic mechanisms of human vision. There are seven official diagnoses of color blindness: four different types of color blindness fall in the red-green category, two are in the blue-yellow spectrum and one version describes a type of vision completely lacking in color. What are the different types of color blindness? The physiological manifestations of each are the same, though. To make navigation of the topic even more interesting, variations can be further divided into inherited and acquired types of color blindness. The categories are nested, and some versions that are designated as distinct conditions manifest in similar ways. The severity of color blindness can vary, and most people with color blindness are still able to see some colors.The question of how many types of color blindness exist can be confusing. It is caused by several factors, including inherited genetic factors, aging, damage to the eye or optic nerve, certain medications, and exposure to toxins. In conclusion, color blindness is a condition in which a person has difficulty seeing certain colors or has difficulty distinguishing between different colors. The severity of color blindness can vary, and some individuals may only have mild difficulty distinguishing between certain colors, while others may have more significant difficulties. It's important to note that color blindness is not a complete loss of color vision, and most people with color blindness are still able to see some colors. Exposure to toxins: Exposure to certain chemicals and toxins, such as lead and mercury, can also cause color blindness.Certain medications: Some medications, such as certain antibiotics and anti-inflammatory drugs, can cause color blindness as a side effect.Damage to the eye or optic nerve: Trauma to the eye or optic nerve, or diseases such as cataracts or glaucoma, can also cause color blindness.Aging: As we age, the cells in our eyes can deteriorate, leading to a decline in color perception.This type of color blindness is usually caused by a defect in one of the genes responsible for the production of color-sensitive photoreceptor cells in the retina.

Inherited genetic factors: The most common cause of color blindness is an inherited genetic factor, which is passed down from parent to child.There are several causes of color blindness: Color blindness is a condition in which a person has difficulty seeing certain colors or has difficulty distinguishing between different colors.
