Winter vacation is approaching, many students’ eyesight is declining to different degrees, according to the school census shows that in the family of glasses wearers, some of the myopic glasses are not properly corrected, and there is no formal ophthalmologist to conduct optometric examination, which results in eye fatigue of eyeglasses wearers and accelerates the refractive error increment of myopia gradually. Another part of the students’ vision loss is not long, belongs to the eye fatigue caused by eye ciliary muscle over-adjustment, the formation of intraocular muscle spasm caused by vision loss, that is, usually the so-called medical “pseudomyopia”, these students if rushed to wear glasses will result in a fake into a real, so that the pseudomyopia becomes real myopia. Because young people’s eyes develop at different speeds and use their eyes at different levels, all of which can cause blurred vision, some of which only belong to the stage of abnormal phenomena, not really myopia, if you wear glasses immediately, the eye axis will gradually lengthen, and the eyeballs gradually lose the ability of biological self-recovery. Therefore, when your child first complains of not being able to see things in the distance, don’t be too busy to give him glasses. If he has temporary low-grade myopia, try to give the eyeball a chance to heal itself through medication, and maybe the child can get rid of the burden of wearing glasses forever. For different degrees, different nature of myopia, treatment methods are different, adolescent myopia, especially the first incidence of myopia, need to be treated with caution, not easily with glasses, do need to wear glasses, but also need to be treated with caution. During the summer vacation, for those who have been wearing myopia glasses before and whose vision is not normal, they should go to regular hospitals to find ophthalmologists who have the right to prescribe glasses for a correct refraction examination, so as to fit the right glasses and make their own myopia refraction get the right correction. Optometrists have a clear concept of corrective eyewear: to make your glasses “clear, comfortable and long-lasting”. This reduces visual fatigue and prevents the progression of myopia. In addition, during the winter vacation, the weather is cold, so many students stay at home for a long time to avoid the cold, watching TV, playing computer, playing games, the body is recuperated, but the eyes do not get a good rest. Many students at the end of the winter vacation, the eyesight of the eyes on the contrary declined. Therefore, during the winter vacation, parents should be more concerned about their children’s eyes, so that they can properly relax and rest, to take comprehensive preventive measures to be effective. 1, strengthen eye adjustment training, such as advocating children to look at the distance, counting leaves every day. 2, in life to maintain adequate sleep, teenagers sleep time is generally 8-10 hours. 3.Limit the playing of computer games on cell phones, try not to watch or watch less television. 4, the diet of caloric energy and a variety of nutrients should be complete, should be given high protein foods such as meat, fish, milk and so on. Vitamin A is important for the formation and play of the visual function of the eyes, and vitamins can not be synthesized in the body, it is necessary to take from food. Animal liver, dairy, egg yolk, cod liver oil and other vitamin A content is high. Fresh fruits contain a lot of vitamin C, diet should not be partial. 5, strengthen the field physical exercise, such as playing table tennis, badminton, swimming and so on. In the winter can be used at noon when the weather is warm, appropriate outdoor activities or walks, so that the eyes see more distant scenery, let the child go out: “wild a wild” more contact with nature, see more green. Through the winter vacation on the children’s eyes myopia prevention and treatment, so that their eyes can be restored to normal, in the future semester have more energy and good eyesight to cope with the academic needs.
