Vision tests assess and identify the imperfections and gaps of the visual fields as well as test the abilities of the eyes to perceive color. The most commonly used tests for vision include visual tests for acuity, refraction testing, visual field tests, and color vision tests.

A test of visual acuity is conducted to determine the eyes' ability to detect objects at different distances. It also requires understanding letters and various sizes of symbols within the eyes chart.
The eyes are assessed individually, and then using corrective lenses, and later without lenses. Acuity tests of various kinds can be conducted to determine the acuity of the eyes.
Refraction tests determine the necessity of a corrective lens. They are based on the acuity test where refractive errors are assessed on the basis of the person's nearsightedness as well as farsightedness.
These mistakes occur when light rays do not focus on the retina when entering the eye, leading to blurred vision. This test is part of routine tests carried out for patients wearing contact lenses or eyeglasses.
It is conducted when the acuity tests yield an eyesight report that is lower than normal and maybe improved with glasses.
The tests for the visual fields are generally used to determine and evaluate areas of the eyes. The term "visual field" refers to the whole area that is perceived by the eyes when they are focused in a specific direction.
