Since the first moment of the birth of the human eye to light entering the retina and begin the path of growth in the visual nervous very quickly up to the age of 3 years, then slow down the growth to be completed at the age of 5 years to 6 years or a little more 
A person is considered to be severe if the natural eyesight sharp eyesight 6-6 for each eye, and distinguish colors and vision in the field of natural limits, and this requires the growth of normal retina and in particular its position and called the premise, as well as the optical path nervous, add to that there is no duplication in the form of visible body and that any three-dimensional stereo, and this requires the growth of normal external eye muscles and nerves, as well as a fusion image from the one sent from the eyes with the other located in the brain which lead to the fulfillment of the visual image. And adopt the natural growth of the network and the course of nervous-catching in the brain to be what we see in the image of a precise and clear on the network since the first moment of the birth of Rights. The growing accuracy of the composition of the image on the retina and the growth of the eye since the birth of the baby until the age of two years or 3 years, with a sharp eye to the 9-6 or 6-6. That is why the period from birth to 3 years, most dangerous phase in the growth of sharp vision, and should correct any defects in the eye so as not to be affected by the growth of the retina and visual path nervous. The growth of external eye muscles to complete at the age of 3 months to 6 months to become compliant movement of the eyes in all directions so that their movements and the status of vision grows naturally in the brain. It consists of the picture we see a similar way to the web image on the film in the camera, so that the liquid and the cornea and anterior lens of the eye and the role of the glass body, the camera lens, iris and play the role of usher light, and play the role of the web film. Therefore, any congenital or acquired defects affecting these parts of a negative impact on the natural growth of the sharp vision, especially if this happens at a critical juncture in the growth of the eye before the age of six, which leads to a Ghamc. What is Ghamc? Ghamc sharp eyesight is weak (although the use of glass) in one eye or both, which can not be explained by the existence of a direct defect in the structure of the eye or the optical nerve to track the status of vision in the brain. Causes An understanding of the way and how they lie behind a Ghamc is still far from perfect so far, and current information is the result of scientific research behind struggling to understand how these so as to arrive at the ideal treatment. We have conducted research to determine the cause of the laziness of the web and found that the reason the eye is subjected to disruption in the natural growth of the process of vision, which is made in the first five years of age. It is for these reasons that strabismus and refractive defects in the cornea or any disorder affecting the quality of the composition of the image transmitted to the mediation of the eye center in the visual brain. Ghamc impact on the region of central retina, an area vital for eyesight, but vision does not affect the parties to the retina. How to prevent The laziness of the web, which begins in early childhood is the highest among other reasons causing the weakening of the sight in one eye. This fact should be taken into account if we know that most of the cases Ghamc can prevent or treat its effects on the eye and treated if detected early. Therefore highlights the importance of periodic medical examinations of children, especially before the age of five years, where the greatest chance of success of treatment. So far, however, did not materialize a preventive system to curtail a specific medical problem. Ghamc types: Network, combined with laziness Balihul This is the most common species. In this type, we find that one of the eyes with sharp sight, and the other a normal weak and suffering Xlanp strabismus. Network, combined with laziness, depending on refractive Eye This type is difficult to detect the mediation of the child; child's eye, because the surface appears to be normal, but the fact that one of the eyes suffered visual impairment, and dependent entirely on the child's one eye-catching. Such cases are discovered during the periodic disclosure at the appropriate doctor. Laziness Alcbchetin accompanied by refractive defects eyes The lack of early detection and treatment of refractive defects lead to the injured eyes Bghamc. Laziness, combined with the idleness of a warning network for the optical path of the nerve-catching The incidence of this type for a few other species. Ghamc occurs due to the presence of the opaqueness of the cornea or the front room or back room or the body or the glass lens on the eye before the age of five years, due to congenital or acquired diseases, and lead to the most difficult types of Ghamc treatment. And even more difficult if the Alatamp treatment in one eye. This type may occur due to overfishing in the coverage of the eye which is one of the means of treatment Ghamc!! It therefore becomes necessary to follow closely the mediation of a competent physician. Diagnosis and treatment Be mediated by the diagnostic measurement of acute vision in children under five years of age, and diagnosis should be based on the measurement of one-time, but it should be measured more than once in different visits to the doctor, in order to avoid misdiagnosis due to the inability of some children to focus in the course of the measurement sharp vision. The discovery Ghamc before the age of five years, leading to most cases in response to treatment, and improved acute vision, but in some cases are not amenable to treatment, such as cases, accompanied by a congenital lack of growth in the optic nerve, which has no cure. In general, treatment Ghamc includes the following: The opaqueness of the removal of any impeding vision, such as Messrs. White (White Water). Correcting refractive defects mediated medical glass. Web Alexlanp through the revitalization of the program to cover the good eye for periods determined by the doctor concerned strictly with the obligation of parents and children the proper coverage and regular follow-up to measure the response of the retina Alexlanp treatment which may extend for several months. In cases of Ghamc accompanied Balihul include treatment-mediated networking Alexlanp sound coverage to the eye to improve eyesight sharp Alexlanp network and then to correct strabismus surgically if necessary. These are the methods of treatment, in general, but the treatment is a difficult medical Ghamc, as the network Alexlanp response to treatment depends on the patient's age and the degree of laziness and the commitment of the patient's retina treatment instructions. Therefore, the doctor may decide to stop treatment if the response did not occur during the 3 months to 6 months, despite the commitment of the patient. Even in cases that respond well to treatment, there are 50% the proportion of relapse, and after the success of treatment should be to maintain the coverage of eye for an hour to 3 hours a day with follow-up every 6 months and the mediation of the competent doctor until the child reaches 8 years to 10 years of age
