The Roles Of A Vision Tester

By Marissa Velazquez


Vision tester is a small instrument commonly found in health centers. This one is used to particularly diagnose eye complications. It is after diagnosis that the health providers get to determine the correct remedy for particular complications. The machine occurs in varying sizes, depending on complexity.

There are a number of eye defects which are usually detected by this machine. The first problem is short sight. This is the kind of problem in which the affected individual is only able to see the objects which are close to them. Objects beyond a given distance cannot be seen clearly. The distance beyond which objects cannot be seen well determines the severity of the complication and this is what is considered when offering the correct remedy.

Other people may have the capacity to see objects which are distant from them, but not those placed very close to them. It this case, the image of the close objects is also poorly focused. Thus, their images are formed behind the retina rather than on the retina. These people too need aids in order to view the images the way they are supposed to be. This problem however is not as prevalent as the short sightedness.

Remedy is determined by the nature of the problem, as well as affordability. The most commonly used and affordable remedy is glasses. These glasses usually are made using different lenses. These lenses differ in terms of the magnification strength. The stronger the lens, the more expensive it is at the health centers providing it. This solution has been mostly applied in solving problems of short sight and long sight.

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, some people who live in abstract poverty may not afford to use this machine. This is because some health centers may charge high amounts of money for the facility. Some of the operators are also the kinds who have not been trained well. These ones thus may lead to faulty diagnosis which in turn leads to wrong medication. Such cases have resulted in consequences as severe as death.

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.
