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 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 so many visual exams that can be done. Sometimes they are mandatory. One example of this is the test that is given to people before they can get a driving license. Another example would be a person who is applying for a position in which good vision is a must, and the potential employers asks that they have a exam done to be considered eligible.

Every test varies and will produce different results. Some may be used to check color blindness and others to analyze ability to see up close and far away. Others might be solely used to check the function of various eye parts. Consult with the physician to figure out which one you should have done. These professionals can also help when it comes to analyzing results and figuring out a treatment plan.

It is important to take care of the eyes because human beings only have one natural set. If vision or eyes are lost, there is not too much that can be done when it comes to restoration. Tester is a term that may describe a person or machine that is involved with assessing the overall health and function of this body part. Numerous exams are available to do testing of the eyes.
