How to protect children's eyesight

Amblyopia is one of the most common eye diseases in children, and it is also a serious eye disease that endangers children's visual function. Amblyopia occurs when the corrected visual acuity of one eye or both eyes is still less than 1.0. The cause of amblyopia is that in infancy, due to perception, movement, conduction and central nervous system, they fail to receive appropriate visual stimulation, which affects visual development and leads to visual dysfunction. Some children with amblyopia also have congenital low vision function, and most of them are complicated with strabismus, hyperopia, astigmatism and other eye diseases.

Take part in outdoor activities as much as possible in summer

Dr. Qu Jifang of Ophthalmology Department of children's Medical Center reminds that amblyopia children's usual performance is very similar to general myopia, hyperopia and other symptoms, so they are often overlooked by parents. The existence of amblyopia will hinder the normal development of children's vision. In principle, the treatment of amblyopia should be found, diagnosed and treated as early as possible. If it can be found in time before 4 years old, it can achieve a more satisfactory therapeutic effect. But if not treated before the age of 10, it will have a serious impact on children's vision in the future.

Bad eye habits are the biggest threat to children's vision. It is suggested to read for less than an hour, do eye exercises or look far away when you are intermittently; the distance to watch TV should not be too close, it is better to be four or five times of the diagonal line of the TV screen. Children like to play computer games for several hours. The blink frequency is reduced to once every 10 seconds or even 20 seconds. During this period, their attention is highly concentrated and the amount of tear secretion is insufficient, resulting in 'dry eye syndrome' and even corneal damage. Experts suggest that children 'return to nature' and have more outdoor activities.
