Color vision tests are performed to determine color blindness and the ability of the eyes in distinguishing the different colors. Although part of regular eye check up programs, color vision tests are also performed on patients who suffer from retinal diseases or are expected to develop color blindness due to hereditary causes. Moreover, these tests also form an integral part of the selection procedures for specific employments such as electronics, military or driving where the right perception of colors plays a crucial role.
While going through color vision tests, patients are shown sample patterns of numbers and symbols, which they need to identify. The test is conducted for each eye separately, by covering the other and the consultant or the doctor holding up the patterns at a specific distance from the patient. The symbols and numbers tend to blend with the patterns and can only be identified by their color, which, if the patient is color blind, becomes quite difficult and confusing.
No discomfort or pain is associated with color vision tests and it does not require any specific preparations. In addition, there are no risks involved in color vision tests. It is rather interesting and fun to check the ability of individual perception of colors through more confusing patterns displaying shapes, symbols, and numbers merged into them.
Individuals with normal eyesight may be able to figure out the numbers and symbols easily and those with color vision problems might face difficulties in distinguishing and separating the colors of the background from the numbers and shapes. They might even perceive different patterns and shapes when compared to people with normal vision.
The tests mostly last for only a few minutes and depending on the nature of perception, the type of the problem may be determined. Color vision problems may result from various consequences that can be discussed with consultants according to individual symptoms and past medical records. Several online color vision tests are available to help individuals detect their color-blindness on their own. Detailed answers and guidelines are provided about the results and about the possible problems that might lead to a different perception of the color than what is normally expected.
