Vision- The process of interpreting our visual world through sight starts with light entering the eye through a transparent layer called the cornea. The cornea is formed by a structure that is made up of a connective tissue layer called the sclera. Just inside the cornea is the iris, which is the colored part of your eye and is able to contract. The contractions control the amount of light that enters the eye. The opening of the iris is the pupil, which works with the iris. As the iris contracts, the pupil adjusts its size. Located behind the iris is the lens, which is responsible for making adjustments to focus images into the light-sensitive membrane called the retina. The retina is made up of five layers of neurons. The cells of the retina receive and process incoming visual information. Rods and cones, also called photoreceptors, continue to send the information to a layer of bipolar cells, and then onto a layer of ganglion cells. The axons of these ganglion cells are responsible for conducting the visual information to the brain. The fovea is a structure that allows us to have accurate vision when focused on a specific area. The fovea also contains a high density of cone cells .These cells are responsible for high acuity color vision. Another type of photoreceptor is the rods. They are also located in the retina and are highly sensitive to light as opposed to the cone cells. As the light passes through the…
