Color blindness is a disorder of color vision that occurs due to the lack of certain cone cells. For example,
red-blind pigment defects are red-blind, green-sensitive pigment defects are green-blind, and blue-sensitive
pigment defects are blue-blind.
Total color blindness is a complete dysfunction of cone cells. It is the most serious type of color blindness.
In the eyes of patients with total color blindness, the world is like a black and white TV, with only light
and dark differences, and no color differences. In addition, patients with total color blindness are
accompanied by amblyopia, oscillating nystagmus, and central dark spots. Fortunately, the population of
patients with total color blindness is very rare, most of which are caused by the close marriage of parents.
Red blind patients, as the name implies, cannot see the red light in the spectrum, they cannot distinguish
red, and it is easy to confuse red and blue, dark green, fuchsia and purple. Red blindness is also called the
first color blindness.
Green blindness is called "second color blindness". Green blind patients often see green as gray or dark
black, and cannot distinguish between light green and deep red, purple and cyan, fuchsia and gray. The
brightest part of the spectrum seen by green blind is the orange part
The last is blue-yellow blindness, also known as "third color blindness". Blue-yellow blind patients cannot
distinguish between blue and yellow, but they can distinguish between red and green. Blue-yellow blind
patients are also relatively rare.
