With the continuous enhancement of social civilization

In early childhood, some infants with abnormal eye signs or high-risk disease factors were required to have frequent health check-ups. It is demonstrated by the epidemiological survey that the incidence and cure rate of low vision in children have closely to do with the early detection. It is a rational and common way to have a check-up by professional ophthalmologist at the age of one. In the early stage of school age, the children in the school age have been able to understand and cooperate with many eye tests such as vision test, eye position and binocular visual function test and so on. It is high time of the eye plastic stage, that the amblyopia and strabismus can be found and treated through routine eye check-ups. Moreover, use the eyes under the doctor's guidance, which is conducive to the myopia prevention and treatment. In the young stage, the people with main genetic factors for ocular disease and high-risk systemic factors should be paid more attention than the people in other stage. Such as retinitis pigmentosa, retinal detachment and other eye disease. Regularly eye test will nip the retinosis or other eye disease in the bud. In old age, with the increase of the age, the incidence of cardiovascular disease becomes higher. However, the eye test is the effective way to find out whether there is the cardiovascular disease or not. Additionally, the incidence of some other age-related eye diseases such as cataracts, macular degeneration increased significantly with age. However, there is no good prevention and treatment to Macular degeneration, early detection is the most effective way for the prevention and treatment of that.
