Ophthalmologists, optometrists and opticians are all types of doctors who specialize in eye care. This professional, who are trained and knowledgeable in this field, might also be referred to as a vision tester. Many tests are available to assess health and function of the 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.
There are several other types of eye exams that are performed. In fact, these may be required in certain instances, for example: before receiving a driving license or being considered eligible for a particular job in which good vision is essential. There are many machines and doctors that serve as the vision tester for such screenings.
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 important to take care of the eyes because humans only have one set. In the event of eye or vision loss, not much can be done to restore that for individuals. A vision tester may refer to a person or machine that is used to assess the health and function of the eyes. There are numerous eye exams that can be performed.
