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 be able to see the distant objects very well but not those which are close to them. These individuals are said to be short sighted. There are very many people having this problem. Their images are formed behind the retina. Remedy for this problem is the reverse of the remedy offered for short sight. These individuals in most cases are given convex lenses to help them see close objects.
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.
Some people may however not be inclined to using glasses. These people if suffering from long or short sight may be forced to select more expensive options. These options include those such as laser treatment or surgery, which require more experienced attendants in the medical field. Other patients who just have got eye pains may be given eye drops. These ones contain chemicals which rectify any problem after a period of time.
There are merits associated with the use of this machine in detecting eye complications. For one, the results are usually very precise. This is because it can identify the various levels of severity of a given condition. The equipment is also readily available and thus can be easily obtained by all health centers interested in providing this facility to patients. Operating it is also simple.
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.
