It is simple to experience the world of a blind person by closing the eyes. If one person with his or her eyes closed tries to walk around, difficulty is probably the only sensation. In most cases, he will be unsure of how many steps to take and in which direction. Stumble is the most likely consequence. In a serious case, injury will occur. This example shows how crucial normal eyesight is for ordinary individuals. Everyone has to appreciate his or her precious vision.
In order to keep the eyes as a window clean and wide open, it is necessary for every individual to take good care of the eyes. Eye care involves all aspects of daily life. The commonest eye problem is myopia, which causes patients to have difficulty in perceiving objects far away. For instance, some people have to squint when they watch television or read newspapers. For some other individuals, they may have to sit exactly in front of the TV set, or work in a computer that is only one inch away. All these improper ways are actually indicating some forms of vision problems. Experiencing vision difficulty, people should not be too lazy to skip an eye examination. Instead, they should arrange a visit to an ophthalmologist’s office as quick as possible.
Vision defects such as myopia and hyperopia have different reasons. One possible reason is inheritance. Hereditary genes are sometime decisive factors of vision problems. In this case, the whole lineage will be scapegoat. Another reason is nutritional deficiencies. For instance, a lutein deficiency is closely associated with age related macular degeneration. Natural aging is also a major contributor to vision problems.
There are kinds of remedies for vision defects. A simple way is to wear corrective eyeglasses or contact lenses. “Treatment” from this source is just temporary that eyesight can never be improved. In order to prevent the eyesight from deteriorating, other measures are needed. It is necessary to push the sofa to the very back of the room, making it farthest away from the TV. After a certain period of eye usage, learn to keep the eyes closed for several minutes.
