New AdaptDxPRO® Technology At Wyomissing Optometric Center
Wyomissing Optometric Center • June 10, 2020
Wyomissing Optometric Center is the first optometric practice in Berks County to implement the AdaptDxPRO®, a new portable technology to aid in the early diagnosis of age-related macular degeneration (AMD). AMD is the leading cause of adult blindness in developed countries. Early diagnosis is key to slowing down the progression of the disease process. MacuLogix
introduced the original AdaptDx® in 2014 as the first fully-automated dark adaptometer for clinical use. Since then, hundreds of practices and thousands of eye care professionals have been using dark adaptation to diagnose and monitor AMD.
What is dark adaptation?
Dark adaptation is the ability of your eyes to adjust from seeing in the light to seeing in the dark. Think of going from bright sunlight into a darkened movie theater. How long does it take your eyes to adjust? That is dark adaptation. Research shows that dark adaptation weakens at the earliest stages of AMD. This is why you might experience trouble seeing at night, reading in dim light, or adjusting to seeing in the dark. As the disease progresses, night vision difficulties increase.
Why AdaptDx® technology?
Dr. Greg Jackson, Co-founder and Chief Technology Officer for Maculogix developed the first commercially available dark adaptometer, AdaptDx®. He, along with several members of his team, visited Wyomissing Optometric Center to install Berks County’s first portable dark adaptometer, AdaptDxPRO®, on Tuesday, June 9, 2020. This device incorporates a digital camera, a retinal bleaching flash, and a Ganzfeld light source inside a pair of light-obscuring goggles. This technology offers the following advantages:
1. Ability to test patients in any available location, eliminating the need for a dedicated dark room
2. Ability to test many patients with physical disabilities who could not comfortably be tested using the desktop model
3. Ability to test more patients efficiently because of the on board tech Theia
4. Single use disposable eye cup protectors mitigates risk of transmitting germs
5. Requires less staff contact time with patients, also mitigating risk for transmission of disease
Why Wyomissing Optometric Center?
Wyomissing Optometric Center received the world’s first installed tabletop dark adaptometer in 2014. Since then, Dr. Glenn Corbin President of Wyomissing Optometric Center was involved in the development of this new technology, AdaptDxPRO®. AdaptDxPRO® is now being used at Wyomissing Optometric Center, a recognized leader in providing comprehensive vision and medical eye health care to our community.
Impaired Dark Adaptation: The Earliest Biomarker of Age-Related Macular Degeneration
Light Sensitivity / Photophobia Management Supporting patients who experience discomfort, pain, or visual overwhelm in everyday lighting environments. Light sensitivity—often called photophobia —can make even routine situations feel overwhelming. Bright sunlight, fluorescent lighting, scrolling on a phone, computer screens, and glare from headlights may trigger headaches, nausea, dizziness, or visual fatigue. Photophobia is common after concussion, migraine, neurological conditions, and certain eye disorders. Our occupational therapy–based program focuses on reducing symptoms, improving comfort, and helping patients participate fully in work, school, and daily life.
Visual Field Loss Rehabilitation Helping patients regain confidence, safety, and functional independence after visual field loss. Visual field loss can occur after stroke, brain injury, concussion, neurological conditions, or certain eye diseases. When part of a person’s field of vision is missing, everyday activities—reading, walking, driving, and navigating crowded spaces—can become challenging or even unsafe. Our occupational therapy–led approach focuses on maximizing functional vision, improving spatial awareness, and helping patients return to meaningful daily activities.
Screening & Functional Testing A detailed, functional approach to understanding how your visual system performs in real-life environments. At WOCcupational Therapy Associates at Wyomissing Optometric Center, we believe that vision is more than eyesight—it is a complex system that guides movement, balance, reading, focus, and the ability to navigate daily life. Many patients with concussion, neurological conditions, or functional visual concerns have symptoms that do not show up on a basic eye exam. Our Screening & Functional Testing evaluates how your visual system performs during real tasks—not just how well you see on an eye chart. This helps us identify the root causes of symptoms and design the most effective rehabilitation plan.
Visual Ergonomics & Workspace Optimization Supporting comfortable, efficient visual performance at work, school, and home. Visual comfort and efficiency are essential for reading, computer work, productivity, and overall well-being. When the visual environment is not set up properly, patients may develop headaches, eye strain, blurred vision, neck pain, fatigue, and reduced attention. For individuals recovering from concussion or managing visual dysfunction, even small environmental stressors can significantly increase symptoms. Our occupational therapy–led Visual Ergonomics & Workspace Optimization services focus on designing environments that reduce visual strain, improve performance, and support long-term visual comfort.

A Proud Moment for Wyomissing Optometric Center We are proud to celebrate Dr. Stephen Shalamanda, O.D. ’20 of Wyomissing Optometric Center on being named the 2026 Outstanding Young Alumnus by Penn State Schuylkill. This recognition highlights alumni who, early in their careers, have already demonstrated exceptional professional achievement, leadership, and a strong commitment to their communities.
Improving Eye Movements for Clearer, More Comfortable Vision Oculomotor skills are the eye-movement abilities that allow us to track objects, shift focus between targets, and move our eyes smoothly and accurately across a page. When these skills are not working efficiently, even simple tasks — reading, copying, scanning the environment, playing sports — can feel difficult or exhausting. At WOCcupational Therapy Associates, our occupational therapists provide targeted, functional rehabilitation to improve oculomotor control and help patients use their vision more comfortably in daily life.
Wyomissing Optometric Center is pleased to recognize a special milestone – 2022 marks 40 years for Dr. Glenn Corbin in practice as an optometrist! Dr. Corbin is also the Chief of the Section of Optometry at Penn State Health St. Joseph Medical Center, Reading, Pa. Join us in celebrating Dr. Corbin for 40 years of […]

National Recognition for Early Detection of AMD Wyomissing Optometric Center was one of the earliest adopters of dark adaptation testing to aid in the early diagnosis of Age-related Macular Degeneration (AMD). Our Doctors use the Maculogix AdaptDx® and AdaptDx Pro® to help identify and manage AMD patients early, often before, irreversible vision loss has occurred. […]
