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.
Eye problems are diverse and they range from sight to aching. In terms of sight, there are those individuals who can only see objects which are placed at close range. These people have got quite a chronic problem, since they cannot manage to see objects located at distant places. Their images are usually formed at the front of the retina rather than on it. Remedies for this problem are diverse. Selection of remedy depends on the severity of the problem.
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.
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.
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.
