1, prolonged near eye use is the main source of myopia development; so myopia prevention and control should first start with the problem of reading and writing distance, reading and writing distance as far as possible. Students take a look at the distance during recess time to relax the adjustment of this habit should be developed. If necessary, you can use reading and writing distant glasses, so that the eyes in the state of looking far to see near, while eliminating hyperopia out of focus to stimulate the expansion of the eye.

2, myopia day long adjustment lag, adjustment amplitude sensitivity decline, adjustment collection coordination disorder lead to myopia development. Improve the physical fitness of the eye through visual exercise, mainly regulation and collection, to enhance the ability to combat myopia.
3, research study methods, improve learning efficiency to achieve half the effort, homework as far as possible to complete during the day, to avoid the study habits of night owls, night use of the eyes prone to myopia.
4, the use of the eyes at the same time will consume photoreceptor synthesis needs of nutrition, while photoreceptors at the same time will produce peroxides need to clean up; so nutritionally more food rich in lutein, chlorophyll, vitamin B, trace elements such as zinc food such as dark green purple kale, spinach; carrots, citrus, corn, animal liver, goji berries, etc.
5, the use of single-light myopia glasses is to see far with, strictly speaking not suitable for looking at near, directly look at the near due to the peripheral retina appears after the defocus and prompt myopia development; in order to prevent and control myopia reading and writing look at near when myopia glasses attached to look at the near of the distalization prism is better.
