Step into the world of diplopia with the Diplopia Simulator. Explore the challenges of double vision and clearly show others what you see. Ideal for patient education, clinical use, and professional training, this tool provides a realistic, adjustable simulation of visual misalignment. Available on iPhone, iPad, and Mac. Every individual experiences diplopia differently. With the Diplopia Simulator, you can recreate your own visual misalignment by adjusting prism strength and orientation. Instead of a generic double vision effect, you can closely match your personal experience and share it with family, clinicians, students, or support groups. Experience what it means to read a page of text when every letter is doubled, to walk through a crowded street where people and objects appear in two places at once, or to look at traffic lights and road signs when each one splits into overlapping images. The simulator’s dynamic motion and depth effects make these situations feel realistic, helping others understand why simple tasks can become exhausting or unsafe. By carefully adjusting prism diopters and eye alignment, you can: • Show how far apart your double images appear • Demonstrate whether images are side by side, above one another, or rotated • Illustrate how small changes in alignment can suddenly make a scene readable or completely confusing Precise Visual Simulation The Diplopia Simulator is engineered for accuracy and realism, featuring: • Horizontal prism adjustment up to 40 prism diopters • Vertical prism adjustment up to 20 prism diopters • Rotational misalignment up to ±20 degrees • Symmetrical binocular rendering for natural depth • Realistic indoor, outdoor, and traffic environments with dynamic motion These controls enable clinicians and users to fine-tune the simulation to specific binocular vision disorders, such as strabismus, cranial nerve palsies, or other causes of double vision. Designed for Real Understanding Whether you live with diplopia or work with people who do, this simulator turns invisible symptoms into visible experiences. It can help you illustrate: • Why reading lines of text is slow, tiring, or frustrating • How moving objects and scrolling screens can feel chaotic or disorienting • Why traffic, road crossings, and driving demand extra caution and concentration • How visual misalignment affects balance, confidence, and daily independence Instead of relying on verbal descriptions, you can show exactly what you mean on-screen. This makes explanations clearer, conversations more productive, and recommendations easier to accept. For Patients and Professionals The Diplopia Simulator is a practical tool for: • Patient education in clinic visits • Clinical demonstrations of treatment goals • Low vision and vision therapy training • Rehabilitation planning and progress discussions • Teaching in medical, optometry, and orthoptics programs • Support group sessions and family education By providing an immediate, intuitive view of binocular vision disorders, it enhances both learning and empathy, helping others understand why certain tasks are difficult and why specific interventions matter. Available on iPhone, iPad, and Mac Use the simulator wherever it is needed: • In the exam room, to explain findings and treatment plans • At home, to help family understand your daily challenges • In classrooms or workshops, to teach about diplopia and strabismus • In rehabilitation settings, to discuss strategies and adaptations The interface is straightforward and touch-friendly, so you can set up a simulation in seconds and adjust it live as you talk. Diplopia Simulator is more than just a visual effect. It is a bridge to understanding. Show others how you see the world, foster empathy, and support better conversations about double vision.
