Many persons who need eyeglasses to improve their vision choose to wear contact lenses. Contact lenses and
regular eyeglasses have many things in common. The lenses of both are constructed to improve the patient's vision
and do this primarily by focusing images on the retina of the eye.
Contact lenses allow a greater field of vision because they become part of the optical system of the eye and move with
the eye. They change position as a person rolls his eyes. This means that he is always looking through the center of the
lens, and his vision is not distorted. Because spectacle lenses are rigidly fixed in place and do not move with the eye, a
person often must look through the outer edges of lens area, which usually causes a distorted view. Contact lenses do
not fog up with moisture, and they have no heavy frames. Many athletes find them preferable to regular eyeglasses for
Almost anyone who wishes to wear contact lenses can do so. Many persons find that the initial adjustment period may
involve discomfort and adaptation but that after a short period of time, vision, as well as the lenses, is comfortable.
To be fitted for contact lenses, you should have your eyes examined by an ophthalmologist or optometrist, who will pre-

prescription to make sure that they will give you the desired correction of vision. Then they must be fitted to your eyes to
assure you comfort and all-day wearing time.

when not in use also have antiseptic qualities to prevent any contamination of the eye.
Lenses should be handled carefully at all times. If the surface is scratched or the edges nicked even slightly, discomfort
and reduction of wearing time, even eye damage, may result.
Because a contact lens fits directly on the surface of the eye, it can do some things
