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.
An eye exam refers specifically to a series of tests that are performed by an orthoptist, optometrist or ophthalmologist to assess the vision of an individual and his or her ability to discern and focus on objects. In this process, other exams and tests are performed on the eyes. It is recommended by officials in the health care field that people have periodic exams done as routine care, especially since most eye diseases show or produce no symptoms.
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.
There are several other types of eye exams that are performed. In fact, these may be required in certain instances, for example: before receiving a driving license or being considered eligible for a particular job in which good vision is essential. There are many machines and doctors that serve as the vision tester for such screenings.
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 crucial that human beings take care of their eyes, as they are only given one set. If there is vision or eye loss, not a lot can be done to restore it back to normal. A vision tester might refer to a machine or person that is employed for the purpose of assessing function and health of eyes. There are several eye exams that can be taken.
