SpH Eye, or Spasm of the Near Reflex, is a medical condition that affects the coordination of the eye muscles, particularly those responsible for focusing and convergence. The condition is characterized by abnormal spasms and contractions of the muscles within the eye, mainly the ciliary muscles that control the shape of the lens and the sphincter pupillae muscle that controls the size of the pupil. These spasms can cause various visual disturbances and problems with focusing, especially when attempting to see objects that are close to the eyes.
