Unlike a basic eye check-up, a comprehensive eye exam involves a thorough, detailed examination of your eyes and visual abilities. During the exam, one of our expert doctors, Dr. Hwang, will ask you about your medical history, family history of any diseases or health issues, medications you may be currently taking, hospital visits, and your personal lifestyle. All of these are elements that can affect your vision. The comprehensive eye exam includes a number of tests to assess your overall eye health. At Sheridan Optometric Centre in Mississauga, Ontario, we have the top-of-the-line medical equipment and cutting-edge technologies that enable us to provide you with the best quality of care that you and your family deserve. An essential part of any comprehensive eye exam is a refraction test, or as it is more commonly called, a basic vision or eye test. This gives the doctor an idea of what kind of prescription you may need. The refraction test is simple: the patient looks through a special device called a Phoropter, focusing towards an eye chart, which is usually about 20 feet away from the chair. We will test different lenses to see which ones give you the clearest, sharpest vision. https://www.sheridanoptometry.com/eye-care-services/eye-exams
