Ophthalmologists, optometrists and opticians are all types of doctors who specialize in eye care. This professional, who are trained and knowledgeable in this field, might also be referred to as a vision tester. Many tests are available to assess health and function of the eyes.

Eye exam refers to multiple tests done by optometrists, orthoptists and ophthalmologists to check the eyes of persons. It also checks focus ability and ability to discern objects. During the process, other exams and tests may be administered. It is recommended that these exams be given regularly to check for asymptomatic eye diseases and other serious conditions.

There are a variety of techniques and different kinds of equipment used when it comes to basic exams, which are often done externally only. The bare minimum that is done during these exams is a check of visual acuity, extraocular muscle motility and pupil function. The process is used by doctors for detection of blinding diseases, brain tumors and other problems with the brain, or other ocular manifestations of eye diseases. Many insurance providers will cover a portion of the cost for these exams. Prices will vary, as do the cost of glasses, contacts or other treatments.

Visual field tests are exams that can be used to detect any dysfunction in peripheral and central vision, which may be the result of medical conditions, such as brain tumors, stroke and glaucoma. This is done clinically by keeping the gaze of patients fixed while presenting various objects in places in their visual field.

Generally, simple equipment is employed during this process, for instance: Amsler grids, tangent screen tests. However, dedicated machinery may be used and if so, the process is then called perimeter. Other names for this kind of exam include Automated perimetry exam, Humphrey field exam, perimetry, Goldmann visual field exam and Tangent screen exam. A test of this sort may be administered by a technician, with aid from a machine or solely by an automated machine.

Numerous eye exams can be carried out. In fact, sometimes these are a requirement. An example of this would be when applying for a certain job in which good eyesight is necessary or before getting a drivers license.

Each test has its own purpose and will produce different results. Some may be used solely to check for color blindness and others might be focused on accessing vision close up and far away. There are even tests specifically designed to assess health of the eyes. A doctor consultation is the best way to find out what exams to take, what the results mean, and the steps to take based on those results.

It is important to take care of the eyes because humans only have one set. In the event of eye or vision loss, not much can be done to restore that for individuals. A vision tester may refer to a person or machine that is used to assess the health and function of the eyes. There are numerous eye exams that can be performed.
