What is fixation disparity?
By the time a child is around 10 years old, they can see as well as an adult. This means their eyes have developed sufficiently and are working together optimally. The two images coming from the eyes—one from each eye—are processed in the brain. These images are then combined into a single image, a process known as fixation. When the brain is unable to merge the images from both eyes into a single image, vision becomes blurred. This can cause blurry vision or restless behavior and is known as fixation disparity.
