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 numerous pieces of equipment and techniques used for even the most basic of exams. Usually these tests are done externally. At the minimum, they will check for pupil function, visual acuity and extraocular muscle motility. The process can be helpful for detection of diseases that are treatable, brain tumors and other issues, and more. The majority of insurance companies cover the cost of routine exams. Tests and treatments will vary in price.

Visual field tests are designed to determine whether or not there is dysfunction present in the peripheral and central vision. This might be brought on by a health condition, such as stroke, tumors of the brain or glaucoma. The test is clinically done and requires that the patient keep his or her eyes fixed on a certain point while objects are placed in other areas of 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.

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.
