Stereoconvergence refers to the coordinated movement of both eyes to focus on a single object. Synonyms for this term include binocular convergence, ocular convergence, and convergence of the eyes. Other related terms include vergence, which refers to the alignment of the eyes at any distance, and accommodation, which refers to the ability of the eyes to change focus from far to near. These terms are important in understanding how our eyes work together to perceive depth and three-dimensional space. Stereoconvergence is essential for vision and can be affected by conditions such as strabismus or lazy eye.
