Central vision refers to the ability to see objects clearly and sharply in the center of our visual field. It is responsible for tasks that require fine detail, such as reading, writing, and recognizing faces.
The retina is the layer of tissue at the back of the eye that contains cells called photoreceptors. These receptors capture light and convert it into electrical signals that are sent to the brain for processing.
Fovea: The fovea is a small depression in the center of the retina where cones (photoreceptor cells) are densely packed. It is responsible for providing us with our sharpest central vision.
The optic nerve carries visual information from the retina to the brain. It acts like a cable transmitting signals so that we can perceive what we see in our visual field.
