Eye Conditions & Treatments
Overview
In a healthy eye, light enters the eye through the cornea, which is the clear outer dome of the eye. The light then goes through the pupil and passes through the eye’s lens. The lens transmits and focuses the light through the vitreous, which is a clear liquid that fills the middle of the eye.
After passing through the vitreous, the image reaches the retina at the back of the eye. If the image requires acute vision, such as reading, driving, or recognizing faces, the image passes through the macula, which is at the center of the retina.
The retina acts like camera film and captures the images sent to it by the eye’s lens. The retina sends the images to the brain for processing.
How Vision Problems Occur
A malfunction anywhere along the vision path, from when the light first enters the eye to when the image finally reaches the brain, can result in vision problems, including blurred vision and blindness. The most common vision problems are listed below and you click on them to learn more.
