Vision tester refers to a machine used in the medical field. This facility has been used for such a long time. Many health facilities have them, though not all. It is most commonly found in health centers that mainly deal with treatment of the eyes. This equipment is usually operated by well trained personnel.
For instance, there are people who can only see objects which are at a close range and not those far away. Such people are termed as being myopic. This problem results from defective formation of an image of an object in vision. Instead of an image being formed on the retina, distant images in this case are formed in front of the retina. This thus results in blurred vision, resulting in the necessity of aids in vision or some form of medication.
The second problem is that one in which an individual can only see the distant objects. Unlike the individuals with short sight, people with long sight cannot see objects close to them clearly. This problem affects both the old and young people. When the machine is used to detect this problem, images are placed at different distances and the patient asked t identify the distance at which they can see the image clearly.
Some people who are found having the above two complications are usually given glasses. This is because there is no medication that has been identified for the two problems. The strength of the lens offered depends on the severity of the complication identified by the tester. Some people who do not want to use glasses may opt to use contact lenses. Others may also choose to have permanent solutions, among which is surgery and laser treatment.
Not all patients suffer from the above two complications. Some people just have eye aches and other problems such as fibrosis of the lens. For these patients, glasses are not necessarily the prescribed remedy. For them, they can just be given medication which eases all the problems in the individuals. The medicine may be in form of a gel or in liquid form. When in liquid for, it is given in the form of drops.
Individuals who have so far been beneficiaries of the use of this machine appreciate the services offered. The machine on the part of patients and the operator is very easy to use. This then means that both of them are not fatigued or disturbed while using the machine. It is also not very heavy and can be moved from one place to another, making it very reliable.
However, there also are some demerits associated with it. In order for patients to access it, they have to visit a heath center. Those without the means of getting to the health center may thus miss out on the opportunity of receiving treatment using this equipment. Some medical practitioners may lead to wrong diagnosis if they do not know to handle it.
Vision tester is equipment that has helped very many people. More people are being trained on how to use it well. The machine is also now available in the smaller health centers. Most people have appreciated its role in the medical field.
