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.
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.
Other more complex forms of treatment include those such as laser treatment as well as surgery. These methods are quite costly. They however are only recommended in case where the sight problems are too severe to be corrected using glasses. Some people may however just resort to use them because they offer a rather permanent solution. Some of the complications such as aches may just be treated using some gels and eye drops.
There are a number of merits as well as demerits associated with this kind of equipment. There are some which are small in size. These ones therefore make portability from one place to another very easy. When conducting tests, the patients and the operator are not strained at all, making the exercise comfortable for both of them. Operation also does not require much skill.
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 has proven highly instrumental in many places. More health facility providers are now purchasing it for use in their various clinics. Training of the operators is also being conducted intensively to ensure correct diagnosis of complications is done.
