The primary purpose of a visual field test is to identify blind spots or peripheral vision loss. During this test, the ability of a person to see stimuli in their peripheral vision is assessed, which is crucial for diagnosing various medical conditions affecting the visual pathways. For instance, conditions such as glaucoma, optic nerve damage, or neurological disorders can lead to changes in the visual field, revealing areas where vision is diminished or absent. This information can help practitioners understand the extent of visual impairment and develop appropriate treatment plans.

Measuring eye pressure, analyzing color perception, and evaluating depth perception serve different objectives in eye care. Eye pressure tests are primarily concerned with diagnosing glaucoma; color perception tests evaluate the ability to distinguish colors, pivotal in diagnosing color blindness; and depth perception tests help assess binocular vision and coordination. Each of these tests contributes valuable information, but identifying blind spots or peripheral vision loss is specifically the hallmark of a visual field test.
