A comprehensive eye exam in our office is more than just a checkup to see if you need glasses. It is an essential exam for the health of your eyes.
At your exam, the doctor will screen for medical conditions and may recommend further testing for diagnosis of conditions like glaucoma, diabetic retinopathy and cataracts.
Your comprehensive exam may include the following tests:
Visual Acuity: Checks the sharpness of your vision both near and far, by reading an eye chart.
Color Blindness: Usually performed at your first exam, this test rules out color blindness.
Ocular Motility: Your will be asked to follow a moving object to see how well your eyes move.
Visual Field: This test measures how wide your field of vision is while you are looking straight ahead.
Refraction: Better 1 or better 2? This test is done with a phoropter to determine your eyeglass prescription. Different lenses are used to determine your best vision.
Autorefraction: Prior to your refraction, you may be asked to look into an autorefractor, which will to estimate your prescription, and serve as a starting point for your refraction.
Depth Perception: This test will determine if you can perceive a 3-dimensional object.
Dilation: To examine the back of the eye, an eye drop is administered to dilate the pupil. The doctor will then be able to see the retina and optic nerve easily. Dilation can last for a few hours, and you will be light sensitive afterwards. Sunglasses are helpful in reducing glare and light sensitivity when your eyes are dilated.
Slit Lamp Exam: The doctor will examine your eyes using a binocular microscope called a “slit lamp”. Using this tool, the doctor can see the cornea, iris, and lens. The doctor can also use an additional lens to evaluate your retina and optic nerve. This exam can help detect cataracts, glaucoma, diabetic retinopathy and macular degeneration.
Eye Pressure: Elevated eye pressure may be a sign of glaucoma. There are different ways to check your eye pressure; either through a simple “puff” of air test, or through tonometry, which requires your eye to be numbed with eye drops.
