What to Expect During Your Exam

Comprehensive eye exams typically take one to two hours, depending on the extent and complexity of your required testing. Your doctor will administer standard tests, as well as additional screening, if needed, based on any unique signs and symptoms. You can expect a thorough explanation of how to manage or improve any conditions that your doctor finds. You might also discuss beginning to wear visuals aids, such as glasses or contact lenses, or updates to your prescription. After a thorough review of your medical history, your exam will include:

Visual Acuity Test

A visual acuity test measures how clearly each eye can see letters and numbers on a chart from different distances, both near and far. Your results will be formulated into a fraction, such as 20/40. The top number indicates the standard distance at which you were tested, and the bottom number refers to the smallest letter size you were able to read. A patient with 20/40 vision would only be able to see a letter clearly at 20 feet that should be legible at 40 feet. Visual acuity tests are very useful in determining whether or not you need eye glasses. 

Our practice uses cutting-edge technology and advanced techniques to detect, diagnose, and treat eye diseases, help you maintain good eyesight, and in some cases, enhance your vision.


When the eye cannot focus light properly, it is considered a refractive error. Nearsightedness, farsightedness, presbyopia, and astigmatism are all common forms of refractive errors. Your doctor will place a series of lenses in front of your eyes to measure your eye's ability to focus light.


During this part of the eye exam, your pupils will be dilated so that the doctor can view the inside of the eye. Your doctor will use a special magnifying lens that provides a clear picture of the retina, macula, and optic nerve. This procedure can reveal swelling or leaking of the blood vessels in the retina, which are indications of a serious condition known as diabetic retinopathy - a leading cause of blindness in the U.S. A dilated eye examination can also detect glaucoma, an eye disease that damages the optic nerve. 


Increased intraocular pressure is a serious risk factor for developing glaucoma. By gently applying pressure near or against the eye, your doctor can determine whether or not you have elevated eye pressure. Your doctor may insert numbing drops before this portion of your exam. 

Visual Field Test

Your doctor will assess your peripheral vision by asking you to view objects to the side and report what you see. A loss of this type of vision can point to evidence of glaucoma.
