Eye and Vision Exams

Eye exams from your local ophthalmologist are crucial for great vision and optimal eye health. That’s why the office of Dr. Sina J. Sabet offers comprehensive eye exams that ensure your glasses and contact prescriptions are up to date, and your eyes are working at their very best.


The consensus among eye doctors is that you should have a comprehensive eye exam once every year or two — once per year if you wear corrective lenses or have a history of eye-related health issues. Children should have their first eye exam at six months of age, another at age three and another when they start school. From then on, children without vision problems or corrective lenses should have their eyes checked once every two years until age 18.


There’s a big difference between vision screenings and eye exams: the former is designed to detect major vision problems and quickly and cost-effectively as possible, and the latter is a full-scale evaluation of vision, eye health, and potential health risks related to the eyes. Eye exams are the better choice by far, as they give you the bigger picture on the state of your eyes, and offer preventative measures that ensure your eyes are in great shape for years to come.

What to Expect at Your Eye Exam

Whether you’re visiting the eye doctor to update your contacts or glasses prescription, if there has been a change in your vision, or simply because it’s been a couple of years since your last exam, the process will typically be the same. If you are experiencing pain or changes in vision, you may be given specific tests, but here’s generally what you can expect during your appointment.

Personal and Family Health History

Before any actual tests, an optometrist will ask you questions about your family’s medical history — if anyone has had problems with macular degeneration, glaucoma, or retinal detachments, or has a history of high blood pressure, diabetes, or other heart-related issues — as well as ask about your own history. He or she will also ask if you need an update to your prescription.

During the Exam

There are several types of eye exams, including:

  • Eye Muscle Test: You will follow an object with your eyes and the eye doctor will evaluate the muscles that control the eye.
  • Visual Acuity Test: The typical eye exam test where you cover one eye and read from a chart that is across the room with letters in descending size. You may also be asked to read from a card that is held at reading distance.
  • Refraction Assessment: This is done in order to test whether or not you have a refractive error and will need contacts or glasses. This is done using a technique called retinoscopy, when a light is shined into your eye.
  • Visual Field Test (Perimetry): This measures how strong your peripheral vision is.

Will There be an Air Puff Test? And Will My Eyes be Dilated?

Dr. Sina and his team often get these questions. Both the air puff test and having your pupils dilated can be uncomfortable for many patients, but the good news is that technology has advanced so that these procedures are not often necessary. However, it does depend on the reason for your eye exam and what parts of the eye need to be tested. When you call to schedule an appointment, feel free to ask whether or not these tests will be given.

Overall, eye exams are nothing to worry about and your eye doctor will ensure that you feel comfortable throughout the appointment. If at any time you feel scared or nervous, just say stop and we’ll give you some time to ask any questions you have or to discuss any concerns.

Often, eye and vision problems do not have obvious symptoms or signs, but are easily diagnosed. By diagnosing eye and vision conditions early on, our team is able provide treatment options and in many cases restore or prevent vision loss. The American Optometric Association recommends yearly or bi-yearly eye and vision exams, depending on whether you are at-risk or not.

Eye Exam and Consultation

During an eye exam, Dr. Sina Sabet will ask you questions about any symptoms or issues you are experiencing, medications you are currently taking, any blurry vision, your work environment, and your overall health. Family history and previous eye or vision conditions will also be discussed during this part of the examination. Dr. Sabet will consider this information when determining any treatments or recommendations.

Vision Testing

Regular vision testing and evaluations ensure that you always have the clearest vision possible. Our Alexandria ophthalmologist provides regular vision acuity test as part of a comprehensive eye exam. Dr. Sabet will measure how each eye is seeing by using a wall eye chart and a reading eye chart. The results of these tests are portrayed as a fraction, with 20/20 being the standard for normal distance and reading vision. Depending on the results of your vision test, Dr. Sabet may prescribe corrective glasses, contacts, or eye exercises.

Eye Function Testing

In addition to vision testing, an eye exam in our Alexandria office includes testing eye functionality. Our ophthalmologist performs several tests to evaluate depth perception, color vision, eye muscle capabilities, peripheral vision, and responsiveness to light. Several other simple tests are completed to determine whether the eyes are focusing, moving, and working together properly. The test results enable Dr. Sabet to diagnose any underlying conditions that may be impairing the eyes ability to focus or work together.

Eye Health

As part of a comprehensive eye exam, our Alexandria ophthalmologist examines the overall health of the eye through a visual examination and tonometry. Dr. Sabet evaluates eye health by visually inspecting the eye and eyelids using magnification and a bright light. To examine the internal structures of the eye, we may dilate the pupils. Increased eye pressure may be an indicator of glaucoma, so we utilize tonometry to measure eye pressure. After completing these short tests, Dr. Sabet reviews the results and discusses any necessary treatment options with you. Contact us at (703) 370-9411 today to schedule a comprehensive eye exam.
