The visual system | Child Development | Edulove

“Our eyes are the windows to the soul” – Shakespeare

What is the visual system? The visual system includes both the eyes and the brain. Light enters your eye where it hits the retina, which triggers light receptors to send electrical signals through your optic nerve, which travel to the back of your brain where the first stages of visual perception take place.

The eye is a complex and intricate organ that serves a great purpose. The eye is an organ that detects light and sends signals along the optic nerve to the brain. In humans, the eye is a valuable sense organ that gives us the ability to see. It allows for light perception and vision, including the ability to differentiate between colours and depth.

Two aspects that Edulove’s Sensory Cubes- and Playmats address is Visual Tracking- and Perception. Visual tracking is typically defined as the ability to efficiently move the eyes from left to right (or right to left, up and down, and circular motions) OR focusing on an object as it moves across a person’s visual field. Visual Perception is the visual skills needed to understand, evaluate, and interpret what is seen.
