What term describes the coordination of images seen by each eye into one picture?

The term that describes the coordination of images seen by each eye into one picture is "Fusion." This process is critical in visual perception, as it allows the brain to combine the slightly different images that each eye captures to create a single, three-dimensional view of the world. This ability to fuse images is essential for depth perception and helps in tasks that require precise visual coordination, such as judging distances or navigating through environments.

In the context of visual training and health, understanding fusion is important because disruptions in this process can lead to issues such as double vision or binocular vision problems. By fostering strong fusion abilities, individuals can enhance their overall visual function and comfort.

The other options relate to different aspects of vision. Occlusion refers to the obstruction of the view or visual field, which does not involve the coordination process. Astigmatism is a refractive error caused by an irregular shape of the eye, leading to blurred vision rather than image coordination. Hyperopia, or farsightedness, is another refractive error that affects how images are focused in the eye but does not pertain to the combination of images from each eye. Understanding these distinctions helps clarify why "Fusion" is the correct term for this specific visual process.
