How The Eye Works

How The Eye Works

At College Avenue Vision Clinic, we believe education is one of our best tools. Your eyes are fascinating and intricate organs that allow you to see the word around you. Dr. Craig B. Kurtz and the entire staff at College Avenue Vision Clinic want you to share with you how your eyes detect and focus light to create images. Watch the video to learn how the eye works!

Eyes are the organs of vision. Through a complex process, they detect and focus light to create images. Vision begins when light rays are reflected off of an object and enters the eye through the cornea and then pupil. It then passes through the crystalline lens which refracts light to be focused on the retina. By changing shape, the lens functions to change the focal distance of the eye so it can focus on objects at various distances. When light hits the retina, tiny cells, rods, and cones, capture the light signals and convert them into electrochemical impulses in neurons. Rods communicate the object’s shape by reading black and white and shades of gray. Cones communicate the color of the object. Working together, the rods and cones process the light to create an image by triggering nerve impulses that pass to the image centers in the brain via the optic nerve.

We regret to inform you that due to the current health crisis regarding COVID-19, the Vision Clinic will be closed. We will send out emails when we re-open. We have taken into consideration concerns from patients and staff, as well as recommendations by the CDC and American Optometric Association to make this decision. All patients with appointments during this time will receive a phone call regarding rescheduling. If you currently have an appointment it is canceled. When we reopen you will be called and rescheduled. Any patients with needs or concerns can call or email the clinic. We will continue to provide emergency eye care. We will continue to re-evaluate this ongoing pandemic and send updates when appropriate.
