General Details Regarding 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 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 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 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.

So many kinds of exams can be done. In fact, there are certain instances in which this type of screening is a requirement. A common example of this would be the vision test one must take before getting his or her license to drive. Furthermore, a person who is applying for a job in which it is important that they have good vision may be required to have an exam done before being considered for the position. Many machines and doctors are utilized for these types of screenings.

Every test is different and may produce its own results. Some are done solely for the purpose of checking for color blindness. Others are more geared toward checking one's ability to view up close and from far away. There are even some that are done to check the different components of the eyes. Consulting with a doctor in the field can help individuals determine which of the tests should be done and get help analyzing results so that they can move forward with treatment.

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.
