Basic Facts Of A Vision Tester

By Jaclyn Hurley


Optometrists, opticians and ophthalmologist are three types of eye doctors. An individual who is considered a professional in this field of study based on their skill and knowledge is often referred to as a vision tester as well. This term might be used to describe a kind of eye exam or field test. Numerous tests and exams of this kind are conducted to check the health and function of this 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 equipment may be employed for this purpose, such as tangent screen tests and Amsler grids. Dedicated machinery is used in some cases. The test may be done by a machine, human technician or both.

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.

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.

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.
