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 is a general term to refer to tests that are performed by these professionals. They are used to analyze the vision of a patient, as well as their ability to focus on various objects and discern between them. It is highly recommended that individuals have the exams done on regular basis as part of care. This is because there are many different diseases of the eye that can manifest without showing 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 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.
