This is also known as “yellow-blue blindness,” which occurs due to damage to S-cone cells responsible for processing short-wavelength light such as blue. Confusion between pink and gray or white.Seeing green as pale green or sometimes white.And the reason for this is that M-cone cells, which are responsible for processing medium wavelength light, such as green, are transferred to longer wavelengths like red. This disorder is the opposite of the Protan-type, and patients’ retina receives more red light and not enough green light. This test is best for detecting the type of CVD. In this test, patients are usually asked to identify numbers or shapes with different digits within a diverse colored background. Some doctors prefer to use a reverse color blind test to diagnose this disorder. So, they can see more dark red and green.

And this cell’s spectral sensitivity is shifted to shorter wavelengths, and the retina gets too much green light. This is also known as red-green blindness because the L-cones of the retina, which is responsible for receiving long-wavelength light such as red, are damaged. There are different types of this disorder: Protan-type CVD In addition to inheritance, other conditions such as Parkinson’s and Retinal problems also cause CVD. It is a genetic disease that is more common in men than in women as the light receptors in the retina cannot react to different wavelengths and convert them into neural impulses. If chromosomal abnormalities occur in cone cells, people can not correctly identify colors. These receptors are responsible for the correct processing of the primary colors, red, green, and blue, making you see a wide range of hues. There are six million cones in the center of the retina. These receptors are very sensitive to light and transmit light through the optic nerve to the brain by nerve impulses. The retina is covered by millions of light receptors called rods and cones. But if the test results show that you have color vision problems, you must see an ophthalmologist. This test has a variety of forms that you can find online instead of visiting an optometrist.

So what is the best way to diagnose this disorder? The color blind test is the only way to do this, and there is no other way. It is a hereditary disease and occurs more often in men than in women. But others have trouble recognizing blue and yellow. When a doctor performs a color blind test, most patients do not recognize the green and red colors. But that’s not true because they see a limited range of colors, and in rare cases, they see gray everywhere. What do you think about color blind people? Most of you might think these people only see everything in black and white.
