Binocular vision is the ability to use both eyes together to perceive depth and distance. This occurs because each eye views an object from a slightly different angle, allowing the brain to combine these images into a single three-dimensional view. This process is essential for tasks that require depth perception, such as driving or playing sports. The alignment of the eyes is crucial for effective binocular vision. If the eyes are misaligned, a condition known as strabismus can occur, leading to difficulties in depth perception. Proper binocular vision is important for activities like reading, where precise focus is needed on text, and for recognizing faces, which relies on depth cues.
