At Sumner Vision, we strive to provide comprehensive, primary eye care for the whole family. Preventative and routine eye exams are important to maintaining good eye health. Often, eye and vision problems do not have obvious symptoms or signs, but are easily diagnosed by a licensed  optometrist or ophthalmologist.  By diagnosing eye and vision conditions early on, Dr. Sumner 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. Sumner will ask you questions about any symptoms or issues you are experiencing, medications your 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. Sumner 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. Dr. Sumner provides regular vision acuity tests as part of a comprehensive eye exam. Dr. Sumner 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. Sumner may prescribe corrective glasses, contacts, or eye exercises, or specialized treatments to insure a pristine ocular surface and tear film.  A stabilized tear film is very important because 60-70% of the focusing power of the eye occurs at the tear film..

Eye Function Testing

In addition to vision testing, an eye exam in our  Denver office includes testing eye functionality. Dr. Sumner 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. Sumner to diagnose any underlying conditions that may be impairing the eyes ability to focus or work together.

Eye Health Testing                                      

As part of a comprehensive eye exam, Dr. Sumner examines the overall health of the eye through a visual examination and tonometry. Dr. Sumner evaluates eye health by visually inspecting the eye and eyelids using magnification and a specialized microscope. 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 a new type of tonometry to measure eye pressure. The Icare tonometer pictured above is very gentle, and there is no puff of air!   After completing these short tests, Dr. Sumner reviews the results and discusses any necessary treatment options with you.
