Certified Paraoptometric (CPO) Exam – Practice Test & Study Guide 2025

The confrontation visual field test is specifically designed to evaluate peripheral vision, as it assesses a person's ability to detect objects in the outer visual field. During this test, the examiner compares the patient's vision to their own by bringing targets from the periphery into the central vision field. This method effectively reveals any deficiencies in peripheral vision, such as tunnel vision, which can be indicative of various ocular or neurological issues.

In contrast, the other tests listed have different purposes. The color vision test assesses an individual's ability to perceive colors, which is unrelated to peripheral vision capabilities. The contrast sensitivity test evaluates the ability to distinguish between objects and their backgrounds at varying levels of contrast, not peripheral awareness. Lastly, the depth perception test examines the ability to perceive three-dimensional structures and distances, which does not provide information about the peripheral visual field.
