There are also visual dysfunctions such as binocular anisotropic movement dysfunction following movement and saccadic movement, adjustment dysfunction, or developmental abnormalities such as large interpupillary distance between the two eyes and difficulty in gathering the two eyes, which are also prone to visual fatigue.
