General Details Regarding 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 many pieces of equipment and techniques that are employed during these basic examinations, which are typically external. Tests are done to check for pupil function, visual acuity and extraocular muscle motility, at the minimum. The process can help physicians when it comes to detecting eye-blinding diseases that are treatable, tumors or other issues with the brain, or diseases. Most insurance companies will cover routine exams. The prices for the tests, as well as the glasses or contacts, will range.

Visual field test will determine if there is dysfunction in central or peripheral vision, a problem that is common for those with brain tumors, glaucoma and stroke. The test involves the patient keeping the gaze fixed on a specified point while other objects are placed in their field of vision.

Simple tools are applied with this kind of test, such as Amsler grids and tangent screen tests. Dedicated machinery might also be incorporated. The test may be conducted by an automated machine, machine and a technician, or just the technician.

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.

It is crucial to take care of this body part because humans are only given one set. In the event of vision or eye loss, not a lot can be done as far as restoration. A tester might refer to a machine or person that is used in order to assess function and health of eyes. There are many exams designed for this purpose.
