Basic Facts Of A Vision Tester

By Jaclyn Hurley


Ophthalmologist, optometrists and opticians are the different professional eye doctors. A person who is recognized as skilled and knowledgeable in this particular field of medicine might also be known as a vision tester. The term is also applied when referring to some kind of eye exam or visual field test. There are several tests that might be performed in order to check function and health of eyes.

Eye exam refers to a series of tests performed by orthoptist, ophthalmologists or optometrists to analyze the vision of the patient, and his or her ability to focus and discern on objects. In the process, other tests and exams are performed. It is suggested by health care officials that people have exams done periodically as part of routine maintenance and care. This is especially important since many eye diseases produce or show no symptoms.

There are a lot of techniques and pieces of equipment that are used during basic exams, which are often external. As the bare minimum, tests are applied to check for visual acuity, pupil function and extraocular muscle motility. This process can be beneficial for physicians for detecting diseases that are treatable, tumors and problems with the brain, or other serious conditions. The majority of insurance companies cover routine exams. Cost of the tests, as well as contacts or glasses, will vary.

Visual field tests are the exams that are used to determine if there is any dysfunction present in the central and peripheral vision of a person. This may be caused by medical conditions, such as glaucoma, stroke and brain tumors. The test is done clinically by instructing the patient to keep his or her gaze fixed while various objects are placed in their field of vision.

Simple equipment may be employed for this purpose, such as tangent screen tests and Amsler grids. Dedicated machinery is used in some cases. The test may be done by a machine, human technician or both.

There are numerous other kinds of exams that may be performed. These may be required in certain instances. An example would be the test that is taken before one can receive a driver license or one that might be issued in order or a person to be eligible for a job in which vision is important. Many doctors and machines may be employed for such screenings.

Every test is different and may produce its own results. Some are done solely for the purpose of checking for color blindness. Others are more geared toward checking one's ability to view up close and from far away. There are even some that are done to check the different components of the eyes. Consulting with a doctor in the field can help individuals determine which of the tests should be done and get help analyzing results so that they can move forward with treatment.

People should take care of their eyes because when the vision or eyes are lost, they are not always easy to replace or restore. The term tester might be applied to a person or a machine involved with assessment of health and function of eyes. Many different exams are available to check the eyes.
