Eye Health & Vision Exams


Eye Exam and Consultation

During an eye exam, Drs. Courtney and Michelle Thelen 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. Our doctors 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 Annandale optometrist provides regular vision acuity test as part of a comprehensive eye exam. Our doctors will measure how each eye is seeing by using a wall mounted 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. The testing procedure known as refraction (the dreaded "better 1 or 2" test) is used to determine the final prescription for eyeglasses. The eyeglasses prescription can be used to develop a contact lens prescription. 

Eye Function Testing

In addition to vision testing, an eye exam in our Annandale office includes testing eye functionality. Our optometrists 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 Drs. Courtney and Michelle Thelen 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 Annandale optometrists examine the overall health of the eye through examination and tonometry. Drs. Courtney and Michelle Thelen evaluate eye health by visually inspecting the eye and eyelids using magnification and a bright light. To examine the internal structures of the eye, we dilate the pupils, take Optos Widefield Scanning Laser images and Optovue iWellness OCT macular scans. Increased eye pressure may be an indicator of glaucoma, so we utilize tonometry to measure eye pressure. After completing these tests, our optometrists review the results and discusses any necessary treatment options with you. Contact us at (703) 941-4111 today to schedule a comprehensive eye exam.
