What to Expect During Your Eye Exam
An annual eye examination is essential in protecting your vision and health. Before the actual exam we will ask you a few questions about your vision history. If you currently wear contacts or glasses, it is a good idea to bring them to your appointment.
During your comprehensive eye exam, a series of tests are performed to assess your vision and the overall health of your eyes. You need to allow at least an hour to an hour and a half for your appointment. Here are some of the tests that you will likely encounter:
Most people are familiar with the Snellen letter chart, which is used to check the sharpness of your vision. We will have you read letters of varying sizes from the chart to determine how well you can see them from across the room. To test your near vision, a smaller, hand-held chart is used.
This test is used to see how well your eyes work together as a team. We will have you focus on a small object across the room, then alternately cover each eye. Then we will do the test again, but have you look at something closer.
Color Blindness Test
Usually performed during your initial exam, this test will rule out color blindness. Although color blindness can be hereditary, the test can help us rule out certain eye health problems.
During this test, the lights will be dimmed and we will shine a light in each eye as you fixate on a large target. We will use a machine to flip different lenses in front of your eyes and observe how the light reflects from your eyes. This will give us a “rough estimate” of what your eyeglass prescription should be.
This procedure is similar to retinoscopy. We will ask you which lenses are clearer as different ones are placed in front of each eye. Your answers will help us refine the lens power and ultimately determine your final eyeglass prescription.
The slit lamp is a microscope that enables us to look closely at both the external and internal structures of your eyes. We will have you place your chin on the chin rest, then shine the lamp's light into your eye. This highly magnified view will reveal signs of infectio
