A technician will measure your vision, or Visual Acuity-both with your current eyeglasses or contact lenses, and without any vision correction by asking you to read a chart projected across the examination room that consists of numbers and letters that get progressively smaller and more difficult to read as you move down the chart. Next, the movement of your eyes, or Ocular Motility will be evaluated in order to understand how well the eye muscles function together and how effectively they move your eyes into the different positions of gaze. By shining a bright light in your eyes, your pupils will be evaluated to check your optic nerve function. Using a Slit Lamp Biomicroscope we will examine the health of your cornea, check for cataracts and examine your eyelids and lashes as well as the tear film to make sure your eyes are not too dry. 1-2 eye drops will be placed in your eyes so that the eye pressure, called Intraocular Pressure (IOP) can be measured to screen for glaucoma. Checking your Refraction is necessary to determine the eyeglass or contact lens prescription to correct your vision. Once your eye doctor has completed the examination of the front of the eye we will place additional eye drops to dilate your pupils and examine the health of the structures in the back of your eye including the retina and its blood vessels and the optic nerve. The thorough examination of the health of the retina and optic nerve is not uncomfortable, but will make you somewhat sensitive to light and may also blur your vision, especially at near, for a few hours after your eye examination. If you have not had a dilated exam in the past, it is a good idea to have a driver on your exam day. It is important to bring a good pair of sunglasses with you in order to lessen your light sensitivity.
