Comprehensive Eye Exams

Annual eye exams are recommended as a part of preventative health care. Individuals can be unaware of problems because there are often no obvious signs or symptoms. It is important to detect and treat vision problems early in order to maintain good vision and eye health. Eye exams may include:


  • Patient History  – Checks the patient’s general health, medication usage, family history and symptoms, etc.
  • Visual Acuity  – Evaluates how clearly each eye is seeing. Also known as the “Snellen Chart”, this tests distance and near vision. Normal distance visual acuity is 20/20. If you have 20/20 vision, you are seeing clearly at the appropriate distance. This is only an indication of visual clarity and other skills that contribute to overall vision.
  • Preliminary Tests  – Evaluates specific aspects of visual function and eye health. 
  • Keratometry  – Measures the curvature of the cornea, the clear outer surface of the eye. This is important for determining the “base curve” of the contact lenses.
  • Refraction  – Determines the appropriate lens power to compensate for nearsightedness, farsightedness or astigmatism. 
  • Eye Focusing, Eye Teaming, and Eye Movement Testing  – Assess accommodation, ocular motility and binocular vision to determine how well the eyes function individually and together. 
  • Eye Coordination  – Ability of both eyes to work together. The brain fuses the images each eye sees in order to create one clear picture. Eye coordination is a developed skill and done properly, keeps the eyes in proper alignment. Poor eye coordination is often successfully treated with eyeglasses or the correction of other eye conditions, such as nearsightedness and farsightedness.
  • Eye Health Evaluation  – Examines the external parts of the eye, including the cornea, eyelids, conjunctiva and surrounding eye tissue. In addition, the patient’s pupils may be dilated to evaluate the internal parts of the eye, including the lens, retina and posterior section. Doctors will also measure the pressure within the eye to detect glaucoma.
  • Supplemental Testing  – Additional testing to confirm or rule out possible problems, and to provide clarification or further assessment.
  • Digital Retinal Imaging  – As an ongoing commitment for providing state-of-the-art technology, Dr. Rayner and staff are pleased to inform you of our latest addition to the office that will help assure a much more complete eye exam. This optional test is called DIGITAL RETINAL IMAGING where remarkably clear and enlarged photographic images are taken of the back of your eyes (the retina, optic nerve, blood vessels, and other parts). Together, you and your Doctor will view the images of the inside of your own eyes and talk about the results. Your Doctor can instantly evaluate the retina tissue for a wide range of problems, some of which include: Diabetes of the retina, Retinal detachment, Vein/artery disease and Glaucoma.
