Some people may get confused about the words "my arms are getting too short". Actually, this complaint is quite common among individuals who are in their 40s or 50s. What does this means? The reason for this abnormal phrase is that these individuals are often bothered by a condition called presbyopia, which causes them to lose the ability to see things close to the eyes. As a result, they have to hold things such as books or newspapers at an arm's distance because their distance vision remains untouched. A fortunate point of presbyopia is that it does not affect one's distance vision. In this case, it is reasonable to say that the more distant the materials are held, the clearer vision the viewer will experience.
Presbyopia is an eye problem that occurs predominantly in the older folks whose eyes deteriorate as the body ages. In a certain degree, presbyopia is a condition that is inevitable when either a boy or a girl reaches middle age. It is as abnormal as gray hair. The eye's natural lens is soft and flexible when a person is young. And a flexible lens can easily change its shape and its focus power can be easily adjusted. The normal function of the lens is called accommodation. However, the lens will gradually lose its flexibility as the person ages, leading to a decrease in the ability to accommodate. The most obvious symptom of presbyopia is the difficulty in seeing close-up objects. Print materials with tiny letters are extremely hard for presbyopic people to read.
Dealing with presbyopia, the commonest means is to wear reading glasses, which can effectively provide clear near vision, enabling the old to see materials with normal efforts. In addition, the power of reading glasses will continue to increase, in the process of on-going natural aging. And for presbyopia individuals who need frequent visual shifts between near and distance objects, bifocal eyeglasses are more suitable.
