who would take the time to stop to think how the eye works, to give us a visual image of our world. Simply from the light rays that enters in through the open transparent space at the front of the eye called the pupil, and if the surrounding light is very low the pupil size is very small. As the light gets brighter the pupil size gets larger, and letting more light in through the pupil.
The anatomy of the eye lens can refract or bend light rays.
Behind the pupil is the lens of the eye, it is located between the Anterior and Posterior chambers, the lens refracts or bends light rays. The light rays are focused on the nerve cells of the Retina. Aqueous humor, and the Vitreous humor is a clear liquid that fills the empty space inside the eye ball.
The rods and cones synapse with the bi-polar cells.
The Retina hold the rods and cones and the bi-polar cells. Rods are sensitive to light but do not sense color. Cones do sense color. Fovea centralis has the highest concentration of cones on the surface of the retina. The rods and cones synapse with the bi-polar cells which synapse with the ganglia cells which synapse with the Optic nerve. The Optic nerve then sends the signals to the Occipital lobe of the brain for the interpretation of the outside world.
