The Uses Of A Vision Tester

By Marissa Velazquez


Vision tester is equipment used in the medical field. The experts commonly associated with it are opticians. It is normally used in the treatment of the eyes. Many people have got different problems which can be identified precisely using this machine. The centers having this machine also have various remedies for different complications.

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 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 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 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 has served a number of health centers very well. Most people appreciate the service of this equipment so much. Through its use, people have had their sight restored. The centers having it on their part generate very good amounts of income just from its use.
