What Is a Depth Perception Test?
A depth perception test is a scientific method for determining an individual’s depth perception. Depth perception is the ability to estimate the distance of a viewed object. Numerous brain and eye functions are required for correct depth perception. Primarily, both eyes must function in near-perfect tandem for an accurate reckoning of depth and distance. A depth perception test can detect minor flaws in this process that may not be evident in day-to-day life. Depth perception occurs because of minor differences in the location of the eyes in the human face. This results in two slightly different views of the same object, a process called stereopsis. The brain usually processes this visual information automatically, providing a person with a three-dimensional view of all objects in sight, including which objects are closer than others. Variances in sight or brain function can impair this process. A depth perception test can determine whether a person has these visual impairments.
