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 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 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.
