Peripheral Field Expansion 

Navigating daily life can become dangerous when a patient experiences hemianopsia, the loss of half the visual field. Dr. Edward Paul utilizes Peripheral Field Expansion technology to shift images from the blind side into the seeing area, significantly improving safety and independent mobility for stroke survivors.

Have you ever felt startled by a person appearing suddenly from your side because you could not see them approaching? This frightening experience often follows a neurological event that compromises your Visual Field or the entire area you can see when your eyes are fixed in one position. Traditional eye exams often overlook the mobility challenges caused by such a significant loss of peripheral awareness. Our clinic addresses this through a specialized Prismatic Shift, which is the optical bending of light to expand your awareness. We use the Peli Prism™ system to place high-powered prisms above and below your line of sight. This configuration allows you to detect obstacles without losing focus on what is directly in front of you. Improving your navigational confidence is our primary goal during the rehabilitation process. Feeling safe while walking through a crowded store again was a major milestone in my recovery.

The Mechanics of Prism Displacement

Optical engineering provides a solution where medicine often falls short. By mounting horizontal prism segments on a standard lens, we create an artificial awareness of objects located in the blind sector. This process relies on the Contrast SensitivityFunction, or the ability to distinguish an object from its background, to help the brain simultaneously distinguish among different visual inputs. Collaboration between the patient and our team is essential to ensure the prisms are positioned correctly for your specific height and gait. We focus on the Magnification Power and placement of your visual needs to customize every pair of glasses.

Common Questions About Peripheral Field Expansion

How long does it take to get used to seeing through prisms? Most patients require a few weeks of consistent use to adapt to the new visual information. We provide a structured training protocol to help your brain safely integrate these images as you move.

Can I wear these glasses all day long? These lenses are specifically designed for mobility and walking in unfamiliar or busy environments. You might find them less useful when sitting still for long periods, such as while watching a movie or reading a book.

Do I need a special frame to hold these prisms? We select sturdy frames that can support the weight and precise alignment of the prism segments. Our staff will help you choose a style that is both functional and comfortable for your daily wear.
