It is important to protect the eyes and maintain the normal eyesight for preschool children, as the close contact with televisions and computers can seriously threaten the health of eyes. Young children are not able to protect the eyes for themselves, so parents should grasp the skills of eye protection for their children.

The first skill is to provide proper visual environment for children. According to the research, the eyesight of children who are living in the city center is worse than that of children living in the suburban districts. The reason is that the visual environment is relatively bad. Therefore, it is necessary for parents to provide nice visual environment for children. During the critical period of eyesight development, children should be moderately stimulated by the light, colors and figures. The environment full of diverse figures and colors is suitable for children. At the same time, the eyes should not be irradiated directly by the ultraviolet rays, or the eyesight can be affected. The light in the room for children should be both bright and warm so as to protect the eyesight.

The second skill is to form the good habits of reading and writing. When children read and write, parents should ask them to keep proper sitting positions. What’s more, the activities like watching televisions should be controlled strictly so as to avoid increasing the burdens for eyes. The key of protecting the eyes is to adhere to these good habits in everyday life.

The third skill is to supplement essential nutrients for eyes through scientific diet. Different ocular tissues need different nutrients. Children should maintain the adequate intake of protein, vitamin A, vitamin C, vitamin B, calcium and so on to meet the nutritional demands for their eyes. Therefore, parents should maintain the balanced diet for children so as to supplement enough trace elements and vitamins. At the same time, fresh vegetables, fruits and marine products should also be provided for children. Proper foods play an important role in protecting the eyes and improve the eyesight for children. For example, fish contains abundant animal protein, calcium, iron and phosphorus, which can effectively eliminate the muscular tensions of eyes. Sword beans containing rather rich iron and vitamin C are beneficial to the development of crystalline lens. Animal livers can also improve the eyesight for children. But it is not suitable for young children to eat animal livers excessively. Children can eat animal livers one time a week and 50 grams each time.
