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

Visual acuity tests are designed to assess an individual's ability to see details at varying distances. The two primary types of these tests are near vision and distance vision tests. Near vision tests evaluate how well one can see objects that are close up, which is essential for tasks like reading. These tests typically involve letters or symbols presented at a specific distance, usually around 14 to 16 inches away from the eyes. In contrast, distance vision tests measure how well one can see objects that are far away, commonly conducted at a distance of 20 feet. This is crucial for activities such as driving or recognizing faces from afar.

In distinguishing near vision from distance vision, it’s important to recognize that each type addresses different aspects of visual performance, thus providing a comprehensive evaluation of one's overall visual acuity. The correct answer combines these two essential evaluations, which are fundamental in both clinical and practical scenarios in eye care.
