Most of us normally share a common color vision sensory understanding.

Most of the people, however, suffer from color vision deficiency. It means their awareness of colors is different from what most of us perceive.

The most ruthless forms of these deficiencies are referred to as color blindness.

The people with color blindness are not conscious of dissimilarities between colors that are clear to the rest of us.

Usually, the color blindness is an inherited problem. The inherited color blindness occurred due to irregular photopigments.

These photopigments or color spotting molecules are placed in cone wrought cells inside the retina, commonly known as cone cells.

In human beings, numerous genes are required for the body to formulate photopigments, and any deficiency in these genes can direct to color blindness.

Generally, there are three most important kinds of color blindness. All these kinds of color blindness based upon photo pigment defects in the three unusual types of cones that counter to red, green and blue light.

The red-green color sightlessness is the most general form of blindness. It is tracked by blue-yellow paint blindness.

The three kinds of color blindness are absolute lack of color vision, whole color blindness, and rare color blindness.

In some cases, the color blindness is occurred due to some chemical or physical damage to the optic nerve, the eye or the parts of the brain that route color information.

The color vision can also turn down with age.

How is color blindness diagnosed?

The eye care professionals take a variety of tests in order to diagnose color blindness.

All these tests can quickly detect particular types of color blindness.

Ishihara Color Test is the most common test type conducted for red-green color blindness.

The Ishihara color test consists of a string of painted loops, known as Ishihara plates.

Each plate contains a collection of dots in different sizes and colors.

Within the circle, dots are present that form a figure which is clearly visible to those with normal color vision but is not clear for those with red-green color blindness.
