Case Study and Feasibility Assessment
Democratizing Vision:
Virtual Reality for Binocular Dysfunction
by Steven Berg, Ph.D.
February 2026
GOAL: An assessment of the feasibility, viability, and user-centered benefits of transitioning orthoptic treatment from clinical standard-of-care to dynamically-adjusted, home-based VR environments
CONCLUSION: Using VR technology for orthoptic treatment (to help some of the ~3-5% of those in the global population with stereoblindness) has the potential to transform vision therapy into a scalable, accessible, and life-changing digital intervention
TAKEAWAY: By reducing the environmental friction of traditional care and replacing the manual burden on researchers with automated eye-tracking calibration features, these technologies have the potential to solve the problem of a high-value unmet need
Empathizing with the User
Living with binocular dysfunction (such as strabismus or amblyopia) inherently introduces friction into a user's daily life. When the visual system suppresses vision in one eye to avoid diplopia (double vision), it impacts depth perception and quality of life
Current Standard of Care (SoC) therapies often exacerbate this friction rather than relieve it; to design a truly viable solution, we must first deeply understand the pain points of the current user journey
Standard-of-Care vs. VR Intervention
By shifting from physical, clinic-based treatments to a head-mounted display (HMD) ecosystem, we radically alter the user experience dimensions
The radar chart (below) visualizes the stark contrast in user-centered metrics between traditional clinical visits and an adaptive, gamified VR therapy approach
Real-time adaptation: Gaze-contingent displays adjust instantly to the user’s eye movements, removing the friction of manual calibration
Replacing clinical tools with gamified environments (e.g., squashing virtual bugs) transforms a chore into an immersive experience
Designing the Frictionless Journey
The viability of scaling this technology relies on minimizing the cognitive and physical load on the patient
The proposed VR ecosystem introduces a streamlined, home-based process flow that prioritizes user autonomy and continuous, passive data collection for clinicians
Feasibility & Viability Outcomes
By addressing core user needs, the implementation of VR technology has the potential to yield profound quantitative improvements in both adherence rates and clinical timelines
Designing for the user has the potential to directly translate to measurable clinical success
What looks like a measure of success?
Decreased drop-out rate among low-compliance users as compared to standard-of-care
Increased proportion of stereopsis recovery among VR therapy patients relative to traditional treatments
Actionable Insights and Deliverables
UI Contrast & Typography
Insight: Users have inherent visual deficits (e.g., amblyopia, diplopia)
Deliverables:
Implement dynamic UI scaling
Base fonts must exceed standard accessibility minimums
Avoid low-contrast overlays
Ensure crucial navigational elements rely on shape and position, not just color or fine detail
Empathetic Onboarding
Insight: Users may feels anxious about their condition and/or new technology
Deliverables:
A guided, voice-narrated tutorial environment that praises micro-achievements
The system must never frame a failed visual task as a “loss,” but rather as data used “to help the system adjust to you”
Fatigue Mitigation
Insight: VR can induce cybersickness, nausea, and/or queasiness; orthoptic training induces eye strain
Deliverables:
Design 10-15-minute modular gameplay loops
Implement mandatory “cool-down” visual environments (e.g., gazing at a distant, static horizon) to rest ocular muscles between intense therapeutic sequences
Clinician Dashboard
Insight: The secondary user is the clinician who needs easily accessible and equally easily interpretable data
Deliverables:
A web-based portal translating raw gaze-tracking coordinates into simple, actionable visual heatmaps and compliance trend lines
Enable quick, data-driven remote adjustments
