Ophthalmologists, opticians and optometrists are the different types of eye doctors. A professional that is knowledgeable and skilled in this field of medicine may also be called a vision tester. This term might also be used when generally referring to some form of eye exam or visual field test. There are numerous tests that can be performed to check the health and function of the eyes.
Eye exam refers more specifically to the collection of tests that are done by an optometrist, ophthalmologist or orthoptist in order to check the vision of a person, as well as his or her focus and recognition of objects. During this process, other tests and exams may be given. It is suggested by health care professionals that people have these exams done routinely as part of their health care routine, especially because many eye diseases are known for be asymptomatic.
Different equipment and techniques are employed for these basic tests, which are usually done through external examination. The very basic exams involve checking of pupil function, extraocular muscle motility and visual acuity. The process is applied by doctors in order to detect blindness, tumors and other potential eye problems. Most insurance providers will offer some portion of coverage for these tests. Prices will range for the test, as well as treatments.
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.
Numerous eye exams can be carried out. In fact, sometimes these are a requirement. An example of this would be when applying for a certain job in which good eyesight is necessary or before getting a drivers license. There are many doctors and machines that act 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.
It is crucial that human beings take care of their eyes, as they are only given one set. If there is vision or eye loss, not a lot can be done to restore it back to normal. A vision tester might refer to a machine or person that is employed for the purpose of assessing function and health of eyes. There are several eye exams that can be taken.
