Beach Vision Center - The Eye
The retina can be compared to the film in a camera. The light is brought to a focus point by the cornea and lens of the eye. The cornea's curvature is ideally matched to its length in the normal eye. As the normal eye ages, the lens loses the ability to focus for reading and will require the help of reading glasses. This usually begins to affect most people after the age of 40.
The Nearsighted Eye If you are nearsighted, the cornea of your eye is overly curved or your eyeball is too long. This combination brings images of distant objects (street signs) to a focus point in front of the retina. When the light reaches the retina, a blurred image is seen since the light rays spread apart after the focus point.
The Farsighted Eye If you are farsighted, the cornea of your eye is not curved enough or your eyeball is too short.
This combination of factors causes the focus point of the eye to be located behind the retina. When light reaches the retina, a blurred image is seen since the light rays have not been brought to focus prior to reaching the retina.
The Astigmatic Eye If you have astigmatism, the cornea of your eye has a non-spherical shape (like a football) and
does not bring light to focus at a single point. Instead, it focuses images over a range of points producing a blurred image. Both nearsighted and farsighted eyes can also have astigmatism.
Iris
The iris is the colored part of the eye. It opens up in dark rooms and at night to let more light into the eye. Conversely, in bright lights the iris constricts to decrease the amount of
light that enters the back of the eye.
Pupil
The pupil is the black spot in the center of the iris. Actually, the pupil is the name given to the opening in the iris through which light passes.
Lens
The lens is responsible for helping to fine adjust the focus of the eye. The lens changes shape to allow clear vision both in the distance and for reading.
Vitreous
The vitreous is a clear jelly-like material which fills the inside of the eyeball. Light passes through the vitreous on its way to focusing on the retina.
Retina
The retina is a thin film of tissue (like film in a camera) where images are brought into focus. The retina lines the inside surface of the eyeball. The retina is connected to the brain where the visual signals are processed.
Anterior Chamber
Between the cornea and the iris is a space called the anterior chamber. This space is filled with a clear water-like solution.
The cornea is a transparent tissue in the front part of the eye. It is a curved spherical structure that is responsible for focusing the light onto the inside of the eye. Contact lenses sit on top of the cornea to change its curvature and eliminate the need for glasses. The Vision Correction Procedures discussed in this website attempts to improve vision by changing the shape of the cornea.
