The scientists from the National Eye Institute have studied the syndrome of myopia rather carefully to provide the world with the proper definition, causes, risk factors, diagnosis, and treatment of this health issue. It is best characterized by the enlarging eyeball, which turns extra-long from front to back. The person falls under the risk of retinal detachment. Some other problems with eyes may take place. One of them is glaucoma.
Another issue is cataracts. Unfortunately, this problem is relevant for more than 30% of the US citizens. It does not matter what the age of the patient is as every person has equal risks of facing myopia sooner or later. It means the individual gets nearsighted. However, school-aged kids are the first citizens to be diagnosed with this disorder. In the adolescents, the problem usually progresses due to the increased amount of time spent in front of the monitors and TV screens. There is nothing to worry about in most cases as myopia stabilizes in adulthood.
Several things may cause this problem with eyes and vision. If the eyeball gets too long, myopia takes place. It becomes more difficult to focus on things. The light rays concentrate at a point in front of the retina instead of the surface. So, the cornea and lens are the two basic reasons for this health condition to appear. In particular cases, it is a mix of all factors.
