Watch cartoons, train your eyes

This page is about using BinoQuest when eye misalignment depends on the direction of gaze. In some directions their eyes are aligned, while in others one eye starts to drift and the image begins to double. Clinically this is most often incomitant strabismus, decompensating heterophoria, or convergence insufficiency, deviations in which binocular (two-eyed) vision is preserved and the patient is able to compensate for the deviation by their own effort, at least in some direction of gaze.

The goal of the exercise is to strengthen control over eye alignment and to widen the range of gaze in which the patient holds a single image, without the eyes drifting.

I built this app for my son Jonáš. Instead of watching boring pictures and objects on the screen, I offer watching videos in small rectangles. You can play video files from your own computer as well as YouTube videos.

The therapist or the patient builds an individual path precisely into the problem directions of gaze and trains holding single vision in the zone where the deviation usually breaks down. A single intensive exercise in this zone should rather be short, and repeated several times a day. The patient can move the video's position on the screen themselves and thus regulate the intensity of the exercise.

Besides custom training directions, the app contains the most common object-tracking patterns: figure-eight, clock face, horizontal and vertical pendulum, diagonal, line reading, spiral, random targets and more. You can build a plan with your own order and length of exercises.

The app does not replace orthoptic or medical care; it serves as a targeted home complement to it, and your eye doctor or orthoptist decides whether it is suitable.

The app also has an experimental feature in development, camera-based eye alignment measurement and a biofeedback exercise built on it. It isn't reliable yet and I keep refining it. Read more (and how to enable it) on a separate page: Camera-based eye alignment measurement (experimental).
