What Is Eccentric Viewing Training?
Eccentric viewing training is a visual function training technique that involves looking around a blind spot to see an object of interest more clearly, using a healthier part of the retina than the one affected by vision loss.
Request an AppointmentHow Eccentric Viewing Training Works
The goal of eccentric viewing training is to identify a part of the retina close to the fovea that still has good sensitivity, then learn to use it effectively for everyday tasks. This healthier area is called the preferred retinal locus, or PRL. Once identified, a therapist trains you to deliberately shift your eye movements toward this area instead of relying on the affected central vision.
Example
Imagine you’re reading a book. Normally, you look straight at the words, but now there’s a blurry spot in the middle of your vision. A therapist will teach you to move your eyes slightly so you can use a clearer part of your vision to see the words. At first, you might practice with bigger letters or fewer words on a page. As you improve, you can move on to reading more complex text.
Who Benefits from Eccentric Viewing Training
Eccentric viewing training is most often used for patients with central vision loss caused by conditions like macular degeneration, where peripheral vision typically remains intact. It’s a core part of many low vision rehabilitation therapy programs and is often prescribed following a comprehensive low vision evaluation.

What Is Eccentric Viewing Training: Frequently Asked Questions
What is a preferred retinal locus (PRL)?
A PRL is a healthier area of the retina, close to the fovea, that a patient learns to rely on for clearer vision when their central vision is affected.
Who is eccentric viewing training designed for?
It’s most commonly used for patients with central vision loss from conditions like macular degeneration, where peripheral vision generally remains unaffected.
What does a typical training session look like?
Training often starts with simple exercises, like reading large text while learning to shift your eyes toward your PRL, gradually progressing to more complex tasks.
Is eccentric viewing training the same as vision therapy?
Eccentric viewing training is one specific technique often used within a broader low vision rehabilitation therapy program.
How do I know if I’m a good candidate?
A comprehensive low vision evaluation will determine whether eccentric viewing training is an appropriate part of your treatment plan.
How can I learn more about the full training process?
Our Guide to Eccentric Viewing Training walks through each step, from your initial prescription to ongoing practice with an occupational therapist.
