With the warm breeze, early spring is a good time to fly kites. Ophthalmologists recommend that if young children want to regulate their eye muscles and prevent myopia from forming, the preferred program is kite flying. “This outdoor activity helps stretch the body and mind, and it helps kids look as high and far away as possible.” Myopia is caused by excessive near vision and prolonged eye use, which causes tension in the ciliary muscles of the eyes, and kite flying allows children to extend their vision to high and far places, which naturally regulates the eye muscles and helps them relax and rest. “The reason why urban children are far more nearsighted than rural children is that they are far less able to exchange near and far vision than rural children and thus are unable to keep their intraocular adjusting muscles flexible and stretching. Children’s indoor activities are basically near-sighted, so they must find opportunities to look farther away.” Myopia prevention and control experts said. In addition to looking far, looking green is also beneficial for preventing myopia. It is understood that the human eye is most afraid of ultraviolet light, swimming without sunglasses, or in the snow exposure for too long, can be caused by vision damage; and white light, red light on the eyes also have strong stimulation, indoor lights, especially computers, game consoles, television screens on the retina may produce damage. “But nature’s green is just the opposite. Instead of being harmful to the eyes, it is good for resting and resting the eyes. It is the perfect color for human viewing.” Ophthalmologists recommend that in spring, when vegetation is growing, leisurely visits to meadows, hillsides, forest parks and other places are full of new greenery, which is good for the eyes and the mind.
