General Information On A Vision Tester

By Jayne Rutledge


Opticians, optometrists and ophthalmologists are different kinds of eye doctors. The professional that are knowledgeable and trained in this field of health care might also be known as a vision tester. The term may also be applied when referring to a general eye exam or visual field test. Numerous tests of these kinds can be done to check the function and health of 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.

Different equipment and techniques are employed for these basic tests, which are usually done through external examination. The very basic exams involve checking of pupil function, extraocular muscle motility and visual acuity. The process is applied by doctors in order to detect blindness, tumors and other potential eye problems. Most insurance providers will offer some portion of coverage for these tests. Prices will range for the test, as well as 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.

Simple equipment such as tangent screen tests or Amsler grids are often used in this process, but dedicated machinery might also be employed. If dedicated machinery is used during a field test, the test is referred to as a perimeter. Other names for this exam: perimetry, Automated perimetry exam, Tangent screen exam, Humphrey field exam or Goldmann visual field exam. A field test may be carried out directly by a technician, with help from a machine or entirely by a machine that is automated.

A lot of different eye exams exist. In fact, they can be a requirement when it comes to applying for a specific job or getting a license to drive. There are machines and doctors that both serve as vision testers.

Each test is different and can offer different results. Some are exclusively done to check for color blindness. Others are more focused on ability to see up close and far away. There are even tests given specifically to check the health of the different parts of the eye. Consultation with a doctor in this field will help individuals determine the tests they must have done and aid in analyzing the results and moving forward with necessary treatment.

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.
