Cartoon shape, colorful ... ... fancy children's sunglasses, although looking cute, but will unknowingly affect the child's vision. Recently, the Quality Supervision Bureau of Jiangsu Province conducted a random inspection of the quality of children's sunglasses. The test results were not satisfactory and the pass rate was only 68.3%. Wu Shenglan, an engineer from the Jiangsu Provincial Quality Assurance Institute, suggested that parents should buy gray and brown sunglasses for their children. Children under 3 should not wear sunglasses. Jiangsu Provincial Bureau of Quality Supervision, Inspection of children's sunglasses this time using physical optical shop sampling and online shopping sample sampling two ways, of which 23 batches of entity optical shop in the province, online shop to buy samples of 18 batches, including Jiangsu at this stage The majority of middle-to-premium children's sunglasses brands on the provincial market, as well as products of different grades with higher sales on Taobao.
The results of the 41 batches of children's sunglasses checked were not satisfactory and the passing rate was only 68.3%. Among them, the disqualification rate of spot checks in physical optical shops was 4.3%, and the disqualification rate of online shops was as high as 66.7%. Some spotted children's sunglasses did not have the function of blocking ultraviolet rays at the time of this spot check. Children wearing such sunglasses did not use other methods to shade in the sun, causing great harm to children's eyes.
The unsuccessful items for children's sunglasses spot checks include: light transmittance, impact resistance, and signs. Wu Shenglan said that children's visual development requires normal light to stimulate the macular area of ​​the eye, otherwise it may cause amblyopia. Children's sunglasses with a light transmittance of the project were found to have an optical transmittance of less than 30% and accounted for 87.8% of the total. When the light transmittance is lower than 30%, it may not be guaranteed that the macular area of ​​the retina can be effectively stimulated. The spot checks found that the manufacturer of children's sunglasses did not make safety warning notices on the products, nor did they explicitly give any instructions for safe use. Children may wear them for a long time or regardless of occasions because they feel that they are interested in wearing them. Formal sensation deprivation amblyopia may be caused in children's eyes, posing a safety hazard.
According to the standard, sunglasses are mainly divided into light-colored sunglasses, sunshades, and special-purpose sunglasses; according to the light transmittance classification can be divided into 1, 2, 3 and 4 categories. According to children's vision development needs and children's use range, it is recommended that children choose sunglasses with large light transmittance, that is, choose light-colored sunglasses and sunshades, that is, light transmittance is classified as Class 1, Class 2, and Class 3. If you want to choose a category of sunglasses for special purposes for children, sunglasses with light transmittance classified as Category 4 must be used under the guidance of a professional ophthalmologist or optometrist. This information can be viewed on children's sunglasses. If this information is missing, it indicates that the logo item is not qualified. The spot checks of children's sunglasses, logo items in the physical optical shop sampling pass rate of 100%, but the sample of online shop is only 33.3% pass rate.
Studies have shown that children's cornea and lens are more clear than adults, so UV rays are more likely to hit the retina. Ultraviolet rays can damage the corneal epithelium in children and cause burns to the retinal macular area. So children need to wear sunglasses or other sunshades in the sun outdoors. But it needs to be reminded that sunglasses block the visible light while blocking ultraviolet rays, and children's visual development requires sufficient visible light stimulation. In addition to the need to wear sunglasses in their own diseases, all other children can not wear for a long time, wear in strong sunlight for no more than 1 hour, do not wear sunglasses indoors or in a cool place.
