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.
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.
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 can be used to detect any dysfunction in peripheral and central vision, which may be the result of medical conditions, such as brain tumors, stroke and glaucoma. This is done clinically by keeping the gaze of patients fixed while presenting various objects in places in their visual field.
Generally, simple equipment is employed during this process, for instance: Amsler grids, tangent screen tests. However, dedicated machinery may be used and if so, the process is then called perimeter. Other names for this kind of exam include Automated perimetry exam, Humphrey field exam, perimetry, Goldmann visual field exam and Tangent screen exam. A test of this sort may be administered by a technician, with aid from a machine or solely by an automated machine.
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 is different and can offer different results. Some are exclusively done to check for color blindness. Others are more focused on ability to see up close and far away. There are even tests given specifically to check the health of the different parts of the eye. Consultation with a doctor in this field will help individuals determine the tests they must have done and aid in analyzing the results and moving forward with necessary treatment.
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.
