Summer has arrived, many students’ report card eye vision have different degrees of decline, year by year, the incidence of myopia in elementary, middle and high school students is rising, the census of secondary school students in the family wearing glasses some myopia glasses correction is not appropriate, did not get a regular ophthalmologist optometric examination, easy to cause eyeglass wearer’s eye fatigue, so that the refractive index of myopia gradually accelerated. The other part of the student’s vision decline is not long, belongs to the eye fatigue caused by the eye ciliary muscle over-adjustment, the formation of intraocular muscle spasm after the vision loss, that is, the so-called “pseudomyopia”, these students if rushed to commercial stores to wear glasses will cause false into true, so that the pseudomyopia becomes true myopia. Some of them are only stage abnormalities, not true myopia, and if they wear glasses immediately, the eye axis will gradually lengthen and the eye will gradually lose its ability to recover on its own. Therefore, when a child first complains of difficulty seeing things in the distance, don’t rush to give him glasses, if he is temporarily low myopia, he should go to the eye hospital for medical optometry, laser measurement of the eye axis length, if necessary for pupil dilation optometry, such as pseudomyopia through formal treatment, to give the eye a chance to heal itself, perhaps the child can get rid of the burden of wearing glasses forever. For different degrees of myopia and different nature of myopia, the treatment methods are different, and adolescents with myopia, especially first-onset myopia, need to be treated with caution. During the summer vacation, those who have worn myopic glasses before and whose vision is not normal, should go to a regular hospital to find an ophthalmologist who has the right to formulate glasses for a proper refractive examination, in order to wear the right glasses, so that their myopia refractive error can be properly corrected. The optometrist’s clear concept of corrective eyewear is to make the glasses you wear “clear, comfortable and long-lasting”. This will reduce eye fatigue and prevent myopic refractive error from increasing. For children with fast-growing myopia, of course, keratoplasty and RGP are good choices. In addition, during the summer holidays in previous years, the weather was very hot, so many students stayed at home for a long time to avoid the summer heat, watching TV, playing computers, playing games, the body was recuperated, but the eyes did not get a good rest. Many students’ eyesight decreases at the end of the summer. Therefore, during the summer 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’s outdoor activities to look into the distance, 2-3 hours a day outdoor activities; 2.In life to maintain adequate sleep, the general sleep time of young people in 8-10 hours. 3, limit playing cell phones, PAD, computer games, etc., as far as possible not to watch or watch less television. 4.The diet should be complete in terms of caloric energy and various nutrients, and high protein foods such as meat, fish, milk, etc. should be given. Vitamin A is important for the formation and function of eye vision, and vitamin A can not be synthesized in the body, it must be taken from food. Animal liver, dairy, egg yolk, cod liver oil, etc. have high vitamin A content. Fresh fruit contains a lot of vitamin C, diet should not be partial; 5, strengthen the field physical exercise, such as playing table tennis, badminton, swimming, etc.. In the summer, you can use the morning or evening when the weather is cool, appropriate to outdoor activities or walking, so that the eyes see more distant scenery, so that children go out: “wild a wild” more contact with nature, more green. By protecting your child’s eyes during the summer, they will be able to restore their eyes to normal and have more energy and good eyesight to cope with their academic needs in the future semester.
