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.
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.
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.
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, some operators may not be so well skilled. These are the kinds of operators who may lead to faulty results. Some people may also lack the basic finances to benefit from the test. Some infant clinics such as those in the rural areas may not be in a position to acquire this equipment thus limiting patients.
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.
