What is true myopia and false myopia?
Myopia is the scourge of our time. Unfortunately, from the very young age, children spend a lot of time in front of computer monitors, TVs, and lessons. The world does not stand still, every day there is a lot of new information that a person absorbs with the help of the eyes. However, this often leads to the appearance of myopia.
True myopia
Most often, myopia begins to develop in children withSeven years of age, it is at this time that children go to school. Eye muscles begin to overwork on an ongoing basis. In order to allow a person to clearly see near, the lens is compressed by the ciliary muscle. Thus, the eye focuses on reading, writing, etc. The optical power of the lens becomes more powerful, but the ciliary muscle is in tension. When a person looks at the distance, in the case of normal vision, the ciliary muscle relaxes and the objects can be clearly seen at a distance. But with myopia this does not happen. The ciliary muscle remains in a state of tension and it is not possible to clearly see what is at the distance. It is usually a very short time for the transition from a strained to relaxed state in the ciliary muscle. But if the spasms are repeated regularly and compression does not take a long time, this will lead to the development of true myopia. True myopia is of two types - congenital and acquired. The latter case is much more common. Unfortunately, congenital myopia in some cases is associated with irreversible changes in the morphological structure of the sclera. Also biomechanical and biochemical properties are violated, which invariably leads to a loss of visual acuity. Congenital myopia can not always be cured or corrected with the help of conventional optical means, such as special glasses or lenses. In some cases, congenital true myopia can lead to detachment of the retina of the eye. Often, surgical intervention is required. As for acquired myopia, it can be corrected or at least "neutralized" with the help of optical means (glasses, contact lenses). Acquired myopia rarely leads to a complete loss of vision.False myopia
It is very important to distinguish true myopia from false. Types of myopia are quite simple to confuse, but the main difference is that false myopia although, like true, leads to loss of visual acuity and myopia, develops due to overstrain of accommodation. Despite the fact that it is practically impossible to clinically distinguish two types of myopia, physicians rely on their diagnoses for the patient's age. False myopia occurs only in children and adolescents. The main weapon in the fight against true myopia is the identification of the false at the earliest stage of its development. That's why doctors recommend to undergo examinations with the oculist on a regular basis and from an early age.
