What is the depth perception test?

The perception of the depth perception is a scientific method for determining the perception of the depth of the individual. The perception of depth is the ability to estimate the distance of the viewed object. Numerous functions of the brain and eyes are required for proper perception of the depth. Primarily both eyes must work in an almost perfect tandem for accurate depth and distance counting. The depth perception test can detect minor deficiencies in this process that may not be seen in everyday life. This results in two slightly different views of the same object, a process called stereopsis. The brain usually processes this visual information automatically and provides a three -dimensional view of all objects in sight, including which objects are closer than others. This process may disrupt deviations in the impact or brain function. The perception of the depth perception can determine whether the person has these disability.

humans and some other animals, including most primates, have a stereOKOPIC VISION, because their eyes are placed on the front of the head, which allows both eyes to focus on the same object simultaneously. Scientists believe that it provides predatory animals such as primates with the ability to target and capture prey. In modern life, a numerous career depends on the exact perception of depth, including those pilots, athletes and medical professionals. A depth perception test may be required to ensure that a person's vision meets the standards required from his profession. For example, the pilot must have a flawless perception of depth for the safety of the crew and passengers of aircraft.

The perception of depth depends on other visual allusions except stereopsis, such as an existing knowledge of the size of the object. The depth perception test eliminates some of these stimuli to measure vision and brain function. For Examples, a random dot stereotest uses general shapes to force the subject to rely on stereopsis itself for depth analysis. One such test uses plastic leaves different cleanOta to create an illusion of depth.

The simple perception test determines whether both eyes are aligned when viewing the same object known as convergence. Disorders such as amblyopia, commonly called lazy eye or strabism, may disrupt the convergence and perception of depth. These conditions can be easily determined when they are constant or chronic; However, if they occur intermittently, the detection test may be required to detect them. Licensed optometists or ophthalmologists can treat such conditions with therapy, corrective lenses or both.
