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 the exams that are used to determine if there is any dysfunction present in the central and peripheral vision of a person. This may be caused by medical conditions, such as glaucoma, stroke and brain tumors. The test is done clinically by instructing the patient to keep his or her gaze fixed while various objects are placed in 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.

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.

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.
