The Main Features Of A Vision Tester

By Jaclyn Hurley


An eye doctor might also be called a vision tester. The term has also been applied to describe a field test or eye exam that is given. These tests and doctors are available to check the overall function and health of this important body part.

Eye exam typically refers to a series of tests that are performed by professionals in the field. These are usually done to analyze vision of a patient, including their ability to discern or focus on various objects. It is recommended by health care professionals that individuals have these exams done frequently as part of routine care and maintenance. This is especially true because there are many eye diseases that do not show or produce 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 tools are used, such as tangent screen test and Amsler grids, with this process. Dedicated machinery may also be applied. The test might be done by a technician, a technician and a machine, or entirely by an automated machine.

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.

Each test is different and will produce varying results. Some are done solely to check for color blindness. Many are used to check the ability to see far away or up close. There are others that are meant to be used to check the parts of the eye and how well they are functioning. Consult with your doctor to find out which tests are ideal for you and to get an explanation as to what the test results really mean so that treatment can be issued successfully.

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.
