Ögonrörlighet

Ögonrörlighet refers to the coordinated movements of the eyes that allow for visual tracking and focusing. These movements are essential for how we perceive and interact with our environment. There are several types of eye movements, each serving a specific purpose. Saccades are rapid, ballistic eye movements that shift fixation from one point to another. They are crucial for scanning a scene and bringing new objects of interest into our sharpest field of vision. Smooth pursuit eye movements allow us to track moving objects smoothly, keeping them stable on the retina. Vestibulo-ocular reflex (VOR) is an involuntary reflex that stabilizes gaze during head movements, ensuring that the image remains steady on the retina even when the head is moving. Vergence movements are conjugate movements of the eyes in opposite directions, used for focusing on objects at different distances, either converging for near objects or diverging for distant ones. These intricate movements are controlled by a complex network of muscles, nerves, and brain regions. Disruptions in ögonrörlighet can lead to various visual and neurological issues, affecting reading, driving, and everyday tasks.
