A peripheral vision test takes little time and is usually incorporated into the early portion of the eye exam.
The most common type of peripheral vision testing is “confrontational” peripheral vision testing, where your eye doctor asks you to focus on a target directly in front of you (the doctor’s eye, or an upraised finger, for example). With one eye covered, and your focus trained on the target, you’ll be asked to describe things you see in the “side” of your vision.
What’s important to remember is to keep focus on the main target and honestly describe what you see. You’ll then cover the other eye and repeat the procedure.
Peripheral vision loss indicates there may be an eye problem present, one that can then be tested for in greater detail during your eye examination.
There are additional types of peripheral vision testing using automated machines with a series of blinking lights in the outer visual field, or special cards with specific lines and patterns that create forced optical illusions.
No matter what the form of test, know that peripheral vision loss is a serious symptom that needs to be evaluated by a qualified eyecare professional.
