Treatment & Cure

Dynamic Adaptive Vision Therapy (DAVT) is the drug-free approach used to address the SEE Sick Syndrome, offered as a public service by Dr. Roderic W. Gillilan, OD.

What DAVT Involves

Dynamic Adaptive Vision Therapy is described as a drug-free cure for the SEE Sick Syndrome. It does not rely on medication; instead it works through structured visual training designed to reduce the nausea, headaches, dizziness, fatigue, and light sensitivity triggered by seeing motion.

Like physical therapy for the body, DAVT asks for consistent effort over time. Progress tends to build gradually as the visual system adapts, rather than through a single treatment or immediate result.

A Public Service

The DAVT approach is presented on this site as a public service, sharing the protocol developed by Dr. Gillilan since he treated his first SSS patient in 1965. His work training patients continued through 2000 in private practice in Eugene, Oregon, and his findings on vision therapy for motion sickness were published in peer-reviewed and professional literature during the 1980s.

Because DAVT parallels physical therapy in structure, patients and families are encouraged to understand that steady participation supports better outcomes.

Dynamic Adaptive Vision Therapy is presented as a structured, drug-free approach for people whose everyday lives are interrupted by the SEE Sick Syndrome. Rather than relying on medication, the method focuses on guided visual training that targets the way the eyes and brain handle movement, light, and shifting scenes. Because symptoms like nausea, headaches, dizziness, and fatigue often appear during routine activities such as riding in a car, reading, shopping, or watching screens, the goal is to retrain the visual system so those triggers feel less overwhelming over time, similar in spirit to physical therapy for the body, with steady practice building toward noticeable, lasting change in comfort and daily function.

The therapy is typically offered as a public service by a clinician who has researched, lectured, and taught on the connection between vision and motion-related discomfort. Sessions are designed to be practical and repeatable, with exercises and techniques that patients can carry out both in the office and at home. Diagnostic procedures help identify how each person responds to motion and visual load, allowing the program to be tailored rather than one-size-fits-all. By emphasizing skill-building instead of symptom suppression, the approach invites patients to take an active role in their recovery, reinforcing the idea that the eyes, like any other part of the body, can be trained to perform more comfortably under demanding conditions.

Because progress tends to build gradually, patients are encouraged to view DAVT as a process rather than a quick fix. Consistent effort, patience, and honest communication with the provider all contribute to better outcomes, and written materials, videos, and structured exercises help keep the work organized between visits. Many who complete the program report being able to read, drive, shop, and use smart phones with far less distress than before, and they often describe feeling newly able to engage with movies, sports, and other visually busy environments. The broader aim is not only to relieve discomfort but to restore confidence in everyday visual tasks, allowing people to participate more fully in work, study, and recreation without the constant worry that movement or bright light will set symptoms back in motion.
