Whether you're wearing a pair of discount glasses from the clearance bin or a pair of high-end glasses that just came on the market, it all started with an eye exam. You may have had your eye exam as a matter of routine medical check up at your insurance company's request, or because you haven't been seeing things as clearly as you used to. Regardless of the reason, the eye exam is necessary to determine the nature of your vision problem and what type of corrective lenses you're going to need. Eye exams may vary slightly depending on the doctor or reasons for having one, but most will contain a handful of basic elements. Your eye doctor will usually want to hear all about the relevant medical history relating to your overall health and specifically your eye health. Do you wear glasses? Have you worn glasses? Have you had any eye diseases? Do any members of your family have eye diseases? He'll want to see your current eyeglasses and ask if you've suffered any eye injuries that may have affected your sight. Once all of the questions have been asked and answered, you'll probably move on to the eye chart. Most people have used the eye chart before, and it is used to help the eye doctor determine how clear your vision really is. It's best to be completely honest during the eye chart, and not to guess at letters just to try and get as many right answers as you can. An ocular motility exam will help the doctor to determine how well your eyes function when it comes to movement, tracking and reflexes. This test helps the eye doctor tell if you have any underlying problems with motility that need to be looked into more closely. At some point, a series of different lenses will be placed in front of your eyes to determine the degree of refractive error in your eyes, and what strength of prescription you'll need in your glasses. Sometimes eyeglasses aren't needed at all, but all of the vision tests will help him decide if you need some extra help. Some of the other elements of eye exams include a slit lamp examination where a high intensity light is shone into the eyes and an opthalmoscopy to give the doctor a close up view of the retina, macula and other structures. Once the exam is completed, the doctor will give you his opinion on the condition of your vision and refer you to another doctor, if necessary. He'll also write you out a prescription for your eyeglasses or contact lenses if you need any, and let you know when he wants to see you again. If you revealed a family history of glaucoma or other eye disease, you may be scheduled for some additional tests to measure your field vision and intraocular pressure. The eye exam and subsequent tests should provide a thorough understanding of everything that's happening with your vision and the glasses that you need to see clearly.
