Myopia, also near-sightedness called, is one of the most common eye problems for people, especially among the children and adolescence. The myopia is mostly caused by the macular imbalance, which means the myopic eyeball will be elongated because of the pressure by two oblique muscles which bind the eyeball in the middle. Normally, the focus will be right on the retina when the parallel rays come into your eyes, yet the elongated eyeball, caused by the tightness of muscles, brings the focus in front of the retina. So the myopia’s may find it difficult to see far objects clearly. Myopia mainly happens to the young people between the ages of eight to fifteen, but you should not think that age over fifteen does not have the possibility to come into the myopia problem. As we know, a child’s physical and nervous system undergo such a great change during the puberty that they may feel anxious or afraid, also they may face a series of competition and confinement at school. All the changes and competitions result in great strains on the young children and the strain is a potential factor for the myopia and other visual defects. Trying to see the words on the blackboard clearly, fearing to be asked by teacher in class and being afraid to fail in the examination will give a rise to the physical and mental tensions. Actually, as these thoughts are very common among the children, so they have to undergo all the things at school. Also, when the children try to read books, they develop a stooping posture as they crouch lower and lower to their books. Then the headaches, nervous habits and squinting come along with the wrong posture. As times goes by, the children become unconfident and begin to stay alone instead of joining in competitive games. Though their parents persuade them to get together with other children, they feel reluctant. Parents would take the children to the ophthalmologist to get a pair of glasses to correct the vision problem caused by myopia. When the eyes are fitted with eyeglasses, the focus can be formed right on the retina. However, it does not give a good look on the children and they must not like the feeling behind lenses. The eyeglasses actually cut the children off the games which are necessary for human body. It is a vicious circle. As the shape of eyeball remains unchanged and the fundamental cause is not remedied, your vision cannot be improved but become weaker and weaker until the muscles gradually lose its flexibility. According to all the information given above, we can find that the original cause of myopia may be the posture. Stooping over when walking and bending forward when reading should be completely avoided as the cramped neck muscles will cut off the circulation of blood to the brain and eyes. Besides, a person with stooping posture may indicate his inferiority and failure. Stand erect and look straight will give you a new focus on your life. You can see much farther than before because you have the smooth circulation of blood to your eyes and you look more confident. Moreover, you can do some eye exercise to help you to deal with the myopia problem.
