Problems caused by contact lenses

Contact lens problems

Nowadays, there are millions of people all over the world who wear contact lenses. According to the data, 1.65 million people wear them in the United Kingdom alone. Even thought contact lenses are meant to help people who have bad vision, there are also some problems that may occur with people who wear them. These problems are known to almost all people who wear the lenses. When a person wears the lenses, they make certain changes to the cornea. These changes are in structure, turnover, tear production and oxygen and carbon dioxide levels. If there is some conditions that a person is already suffering from, these changes of the cornea can only make them worse. Apart from that, other problems may occur as well. There are certain factors that determine the type of problems that a person may experience if he or she wears the lenses. Some of these factors are the type of lens, the frequency of changing the lenses, the cleaning system used and certain factors related to the wearer. The problems which may occur can be minor but they can also lead to loss of vision.

People who have a history of pain and irritation or watering of the eye have a lot more chance of suffering from some problems when they wear the lenses. If a person thinks that his or her eye does not look good or feel good or the vision is not good, he or she should remove the lens and consider the problem. There is a chance that the problem is in the lens. The lens may poorly fit and if that is the case it will cause damage. Poor lens care can also be the cause of the problem.
