A comprehensive eye exam should occur early in life to ensure proper eye and vision development. Continuing eye health examinations at regular intervals are important as many eye diseases and vision changes can occur without warning signs.  


A complete eye exam involves a series of tests designed to evaluate your vision and check for eye diseases. Each test during an eye exam evaluates a different aspect of your vision.

Another part of the examination involves a slit lamp, an instrument that projects a beam of light on the eye while the doctor looks through binocular lenses for magnification.


Dry eye, infections, cataracts, and scratches on the surface of the eye are some of the disorders that can be detected with this instrument. A numbing drop and orange dye are placed on the eye. With the aid of a blue light and plunger-like device, the eye pressure is measured, one factor in the diagnosis of glaucoma.


Drops to dilate your pupils will be given in order to get a better view into the back of your eyes. Various lights and lenses will be used to check the eye for changes from diabetes mellitus, hypertension, the presence of macular degeneration, and other diseases.

We use a teaching approach so that you not only know your condition but also get educated on the condition.

During a comprehensive eye exam, you'll be asked to read the smallest letters or numbers on a screen to determine your level of vision.


Refraction will be performed in order to determine the best prescription for your glasses or contact lenses. This involves placing an instrument, which contains a large number of lenses and looks like a giant butterfly, in front of your eyes.


While looking at the eye chart you'll be asked an important question: “Which is clearer, number one or number two?" Additional tests will be performed to check for color vision deficiency, eye muscle alignment, pupil reflexes, and peripheral vision.

What about eye drops?

What else should I know?

It's easy to put off an eye exam if you're not having any vision or eye problems. However, when it comes to maintaining proper eye health, we recommend seeing an ophthalmologist for your comprehensive eye examination on a yearly basis or as advised by the doctor. Many eye problems can result in less serious outcomes if diagnosed at an early stage. You will be given clear and detailed instructions for maintenance of your eye health.
