Certified Paraoptometric Practice Test

What does a cover test assess?

1. Color blindness

2. Eye alignment and binocular vision

3. Depth perception

4. Visual acuity

The correct answer is: Eye alignment and binocular vision

A cover test primarily assesses eye alignment and binocular vision. During the test, one eye is covered while the other is observed for any movement. If the uncovered eye shifts to focus on the target, it indicates a misalignment, suggesting conditions like strabismus (crossed eyes) or other binocular vision issues. Additionally, the cover test helps determine the ability of both eyes to work together, which is crucial for depth perception and overall visual function. While color blindness, depth perception, and visual acuity are important aspects of visual assessment, they are evaluated through different tests and methods. The focus of the cover test is specifically on how well the eyes align and function together, making it a vital
