The simultaneous inward movement of the eyes is known as convergence. When both eyes are aligned onto a target, the brain should perceive a single image. Slight inaccuracies in convergence can cause a person to see double vision, or diplopia. Because the convergence visual system is also tied to the focusing system, many people who have problems with convergence also have problems with focusing and thus have blurred vision. This linkage between focusing and convergence is known as accommodative conververgence.
If the eyes cannot converge accurately to achieve single vision, usually the person will have a convergence insufficiency, convergence excess, or strabismus. Convergence insufficiency means that the eyes do not turn inwards enough to lock onto a target usually up close. This will result in double vision, difficulties in reading, and poor reading comprehension particularly in school-aged children who are not treated or are never diagnosed because they assume it is normal.
Convergence excess is when the eyes turn in too much. Symptoms can be quite similar to convergence insufficiency except the treatment is more challenging. The gold standard for treatment for both convergence insufficiency and convergence excess is vision therapy or orthoptics. This involves exercises and activities to improve muscle coordination and focus through a doctor-directed therapy program. The duration of treatment varies on the patient's age and the severity of the condition. On the otherhand, strabismus refers to eyes that are misaligned even while looking straight ahead and not just the inward movement of the eyes. Treatment for strabismus can include just getting a pair of glasses, to adding prism to your lens correction, vision therapy, and eye muscle surgery if the other options are unsuccessful.
The term is convergence.

The medical term for the simultaneous inward movement of both eyes to maintain single binocular vision is convergence. It is an important function that allows the eyes to focus on a near object.
The term that describes the movement of the radius around the ulna is called pronation (inward rotation) and supination (outward rotation).
Yes, "inward" does not have a suffix. It is a standalone word that describes something directed or moving towards the inside.
Inward clearing is a term used in banking. This term describes when a bank receives one of their checks from another bank for processing.
The twisting motion of the foot that turns the sole inward is known as inversion. It involves the movement where the sole of the foot faces inwards towards the midline of the body. This movement is often associated with ankle sprains or instability.
The inward block in arnis, a Filipino martial art, is a defensive technique used to deflect incoming strikes toward the practitioner’s centerline. It typically involves using the forearm or weapon to redirect an opponent's attack while simultaneously positioning oneself for a counterstrike. This movement emphasizes fluidity and efficiency, allowing practitioners to maintain control of the engagement while minimizing exposure to attacks. Mastering the inward block is essential for effective defense and transition into offensive actions in arnis.
they glide with the wave under the surface. they spread out there tenticles and then push them inward to move forward.
Stellar equilibrium is the balance between the inward force of gravity and the outward force of gas pressure within a star. This balance allows the star to maintain its size and shape over time. Any disruptions to this equilibrium can result in changes to the star's structure and behavior.
As a satellite spirals inward, it speeds up due to the gravitational pull increasing as it gets closer to the center of the object it is orbiting.
The first phase of the action potential caused by the inward movement of sodium is called depolarization. During this phase, the cell membrane potential becomes less negative as sodium ions rush into the cell through voltage-gated sodium channels.
