Outdoor activities are the simplest way to prevent myopia, and are internationally recognized, effective and in line with the nature of children and adolescents. Adequate exposure to sunlight can effectively protect vision. So do you know how to do outdoor activities to help your eyesight?
Our comprehensive prevention and control of children and adolescents myopia program recommends increasing students' outdoor activities, we refer to the "outdoor activities" is the outdoor environment with a light intensity of more than 1000 Lux, sunlight can promote the secretion of a transmitter "dopamine" in the eyes, which can inhibit the growth of the eyes; At the same time, the stimulation of sunlight can make our eyes and pupils contract, increase the focus of the eyes, and make us see things clearer, thus helping us reduce the probability of myopia occurring and developing. You’d better bring a filter straw when going outdoors activities.
Therefore, usually during the day, you can take a walk, or play some ball sports, so that the eyeballs can constantly alternately look far and near, adjust and move, constantly promote the contraction and relaxation of the ciliary muscle, effectively improve the fatigue of the ciliary muscle, so as to achieve the purpose of preventing and controlling myopia. Even if the outdoor light intensity on cloudy days can be achieved, but even if it is sunny indoors, this light intensity cannot be achieved, and the indoor light intensity is only a few hundred Lux, which cannot meet the needs of preventing and controlling myopia. To prevent myopia, outdoor exercise for 2 hours a day is essential, after learning, let the eyes soak in the sun, can help us relax the eye muscles, slow down the occurrence of myopia.
