Eye examinations are carried out by the ophthalmologist or optometrist to examine the patient’s eyes to detect various eye problems that might be developing. These problems may include macular degeneration, cataract and glaucoma, and eye infections. The ophthalmologist will check for the following conditions: hyperopia or myopia, refractive errors such as myopia (nearsightedness), hypermetropia (fatigue of the eye) and presbyopia (farsightedness).
How to do Eye Exams
Eye examinations can also be done in order to detect eye diseases related to the iris and the external part of the eyes. A comprehensive external examination includes the examination of the upper lid of the eye, the cornea, the clear and the retinas. The examination of the eyes should include the detection of any change in the form and the color of the eye, blurred vision, halos, shadows and light rings. These abnormal appearances are usually the results of cataracts and the formation of new fibrous structures on the iris.
In addition to the regular eye exams that every individual must undergo, there are certain tests that are considered to be more routine. They are usually recommended by the doctor. If you feel that any of these tests are necessary for your health, then you should talk to your doctor about the schedule of the tests. Normally, it is a good practice to have your eye examinations every year, at least if you are over forty years of age; this is because the vision changes with age. So, if you feel that you need one, you should make sure to schedule an eye exam.
