Eye movement refers to the voluntary and involuntary movements of the eyes that assist with obtaining, fixating and following visual stimuli. The eyes are each connected to a system of six muscles. Light is sensed by the retina, which is a type of tissue that contains cells known as photoreceptors. These cells translate light into … Read more

The eyes have a focusing system called accommodation; it allows for visual clarity. The system is rested when you look at an object that is far away and is not forced to strain like it would if the target were close. In normal circumstances, the eyes are able to effortlessly transition between objects that are … Read more

Each eye picks up a slightly different image, but through a process called fusion, the brain blends the images together to make one three-dimensional picture. Good eye coordination is needed, however, and allows the eyes to sustain proper alignment so that they can focus on practically the same image, though it is seen somewhat differently. … Read more

The eyes, though, begin the complex process of vision by gathering, focusing and passing on visual information to the brain. To help you learn how the eye works, here is a … Read more

Under most circumstances, we use information from both eyes to create a single visual image. This ability to converge information from both eyes is called binocular vision. In some cases, the eyes fail to … Read more
