Opticians, optometrists and ophthalmologists are different kinds of eye doctors. The professional that are knowledgeable and trained in this field of health care might also be known as a vision tester. The term may also be applied when referring to a general eye exam or visual field test. Numerous tests of these kinds can be done to check the function and health of eyes.
An eye exam refers specifically to a series of tests that are performed by an orthoptist, optometrist or ophthalmologist to assess the vision of an individual and his or her ability to discern and focus on objects. In this process, other exams and tests are performed on the eyes. It is recommended by officials in the health care field that people have periodic exams done as routine care, especially since most eye diseases show or produce no symptoms.
Many different techniques and pieces of equipment are used in basic examinations, which are generally external. At a minimum, tests are done on pupil function, extraocular muscle motility and visual acuity. The process itself can help doctors detect treatable eye-blinding diseases, tumors or other problems in the brain, or ocular manifestations of disease. Many insurance companies cover routine exams. Prices for these tests, as well as contacts or glasses will vary.
Visual field tests are exams that are employed to identify any dysfunction present in central and peripheral vision. Usually these problems are the result of glaucoma, stroke, brain tumors or other serious medical conditions. The test itself is done clinically. Patients are asked to fix their gaze on a spot while objects are placed in different areas of their visual field.
Simple equipment such as tangent screen tests or Amsler grids are often used in this process, but dedicated machinery might also be employed. If dedicated machinery is used during a field test, the test is referred to as a perimeter. Other names for this exam: perimetry, Automated perimetry exam, Tangent screen exam, Humphrey field exam or Goldmann visual field exam. A field test may be carried out directly by a technician, with help from a machine or entirely by a machine that is automated.
A lot of different eye exams exist. In fact, they can be a requirement when it comes to applying for a specific job or getting a license to drive. There are machines and doctors that both serve as vision testers.
Each test has its own purpose and will produce different results. Some may be used solely to check for color blindness and others might be focused on accessing vision close up and far away. There are even tests specifically designed to assess health of the eyes. A doctor consultation is the best way to find out what exams to take, what the results mean, and the steps to take based on those results.
Human beings should take care of their eyes, at they only naturally have one. If there is eye loss or vision loss, not much can be done in terms of restoration. A vision tester is the term that may be applied to the machine or professional that checks the overall health and function of eyes. Numerous eye exams can be administered.
