Healthy eyes have a natural ability to converge on an object being viewed in such a way that the image is centered in the macula. You may have noticed that when viewing close objects, your eyes naturally converge, while when viewing distant objects, your eyes align nearly parallel to each other. In both cases, our vision has an extraordinary ability to maintain close and distant objects in sharp focus. Of course, this applies only to healthy vision without convergence disorders.
Proper convergence allows for a deep and accurate perception of depth in the 3D world. The brain automatically combines images from the right and left eyes into a single three-dimensional whole. This ability helps us, among other things, estimate the distance of objects relative to us. Untreated convergence problems can lead to the development of strabismus, either convergent or divergent.

For this exercise, we will use convergence charts. The main goal is to create a virtual image, allowing each eye to work separately, strengthening coordination between the eyes and improving the functionality of eye convergence.
Strabismus (squint) is an eye condition characterized by weakened eye muscles, causing a change in the angle of one eye relative to the other. The result of strabismus is a disruption of stereoscopic vision. You can find more information about this condition here
When training the eye with strabismus, we need to correct the "alignment" of the muscles, that is, try to influence the coordination of the eyes and bring it to a natural balance. Strabismus treatment with vision training can be divided into 2 phases:
This exercise was developed by Clara Hackett, and its aim is to relax the eyes and make them work together.
This exercise was recommended by Janet Goodrich, and as the name suggests, in this exercise, you move an object back and forth, mimicking the movements of a musician playing a trombone.
