Color blindness and common tests for color blindness

[alijen]

Color blindness is also known as dyschromia. This is an eye disease in which people can see things clearly but cannot distinguish certain colors, such as red, green, or blue, or when they are mixed together.
Three common color blindness tests
Currently, ophthalmologists have many ways to perform a color blind test, but the most common are:
Ishihara Color Blindness Test:
Your doctor will ask you to look at a series of circles with dots of different colors and sizes. Some dots form a one- to two-digit number or shape. If you belong to the red-green colorblind group, you will have a hard time recognizing those shapes or may not even see them.
HRR color blindness test:
This test is similar to the Ishihara but helps screen for blue-yellow vision problems.
Cambridge color blindness test:
This experiment is similar to the Ishihara color blindness test, except that it takes place on a computer. You will be asked to find a "C" shape with a different color from the background. The test will appear randomly. If you see the letter C, press one of the four keys as instructed.

A succession of coloured and sized dots are shown in the form of circles, and your doctor wants you to look at them. Some of the dots make up a shape or number with just one or two digits. such of you who are red-green colorblind may have trouble, if not completely absent, recognition of such forms.

The factory balls game starts with a simple white ball, and you must figure out which tools and colors to use in what sequence to construct the desired design. It's an amusing and demanding game that needs inventiveness and problem-solving ability.
