Regardless of your age or physical health,
it is important for that you get regular
eye examinations.
As a general rule, you should get
an eye exam every two years, and
if you are over 65, every year. |

PREPARING FOR YOUR EYE EXAMINATION |
|
If you wear soft contact lenses do not wear them 2 to 3 weeks before you eye exam. If you are currently wearing hard contact lenses, it is best not to wear them for 2 to 3 months before the exam. This will give you cornea time to go back to its “natural” shape and get a more accurate refraction reading. |
AS PART OF YOUR EYE EXAMINATION BE SURE TO
OBTAIN THIS VERY IMPORTANT INFORMATION! |
When you arrange your eye exam, tell your doctor that you
are going to be purchasing a pair of high quality eyeglasses
and as part of your eye examination you need this information. |
 |
A RED-GREEN BALANCE
DUOCHROME TEST. |
|
We have found that the information gathered in the red-green
balancing duochrome test is critical data that will produce
sharper images in your new eyeglasses. |
Another critical piece of information is the pupillary distance.
An accurate pupillary distance (PD) is a required measurement
in order to make glasses. |
|
Your pupillary distance measurement (PD) is the distance in millimeters between your pupils (the centers of your eyes). Your adult PD never changes, and it averages 60 millimeters (mm) for women, and 64. mm for men. Sometimes your eye doctor will write your PD for each eye, for example “33/34” This reflects the fact that for some people, the distance between the nose bridge and eye center is not equal, or asymmetrical. |
Typically, during your eye examination
your eye doctor will focus on five areas: |
When a doctor examines your eyes, he or she is doing more than checking to see if you need glasses. During a complete eye exam, your eye doctor will determine your prescription for glasses or contacts and also check your eyes
for common eye diseases, assess how your eyes work together as a team
and evaluate your eyes as an indicator of your overall health. |
Refractive Error
This is a measure of visual acuity and it refers to your prescription, including nearsightedness, farsightedness and astigmatism. Refractive error is
corrected with eyeglasses, contacts or refractive surgery. |
Amblyopia
This occurs when the eyes are turned or when one eye has a much different prescription than the other. The brain will "shut off" the image from the turned or blurry eye. When left untreated, amblyopia can stunt the visual development of the affected eye, resulting in permanent vision impairment. Amblyopia is often treated by patching the stronger eye for periods of time. |
Strabismus
Strabismus is defined as crossed or turned eyes. The examiner will check your eyes' alignment to be sure that they are working together. Strabismus causes problems with depth perception and can lead to amblyopia. |
Eye Diseases
Many eye diseases, such as glaucoma and diabetic eye disease, have no symptoms in their early stages. Your eye doctor will check the health of your eyes inside and out for signs of early problems. In most cases, early detection and treatment of eye diseases can help reduce your risk for permanent vision loss. |
Other Diseases
Eye doctors can detect early signs of some conditions and diseases by looking at your eye's blood vessels, retina and so forth. Your eye doctor may be able
to tell you if you are developing high blood pressure, high cholesterol or a few other problems. |
