At present, the number of myopia in China has reached more than 600 million people, and with the popularization of digital teaching models, the myopia group is showing a clear trend of younger people. Relevant data show that the myopia rate of high school and college students has exceeded 70%, and the myopia rate of primary school students is also close to 40%.
Now that the summer vacation is approaching, major eye hospitals and professional optician institutions across the country will usher in a wave of optician peaks. Among the dazzling array of eyewear products, the shape, style, frame material, and functional attributes of the glasses are all changing every year. ". In order to better provide guidance for children's glasses, the China Optical Association has recently drafted and completed the drafts for soliciting opinions on the three group standards of "Children's Spectacles", "Children's Spectacle Frames" and "Children's Sunglasses".
Regarding materials, due to the long contact time of eyeglass frames with skin, the draft requires manufacturers to select materials to minimize the precipitation of harmful substances from long-term skin contact parts and meet the requirements of existing regulations. Pay special attention to avoid using substances that may cause allergies, carcinogens, induce mutations in organisms, or toxic.
For spectacle frames worn by children aged 14 and under, the design and production should follow the principle of not endangering the wearer’s health and safety during normal use or reasonably foreseeable abuse. The surface of children's spectacle frames should be smooth, free of blemishes and bumps, no obvious scratches, and rounded edges. There should be no sharp edges that are accessible and potentially dangerous. Children's spectacle frame (metal frame) should be equipped with adjustable nose pads, and the fasteners should not produce sharp points or protrusions that may cause the danger of being touched.
Taking into account the child's active nature, the lenses of children's spectacles should also have a certain impact resistance. For example, under a certain impact force, the lens should not be split into two or more pieces; there should be no fragments falling off the near-eye surface of the lens; the lens should not be directly penetrated.
