TUV Rheinland Sunglasses Test
HONG KONG, June 12, 2017 / TUV Rheinland experts remind that parents should choose children's sunglasses from regular manufacturers, and it is best to choose products with labels that clearly indicate UV 400 nm or 100 percent UV absorption or 100 percent UV protection; all meaning that the lenses can block out all UV light. For children with eye diseases should first consult a doctor whether it is suitable to wear sunglasses, and then according to their own situation with glasses.
The Dragon Boat Festival has passed, summer has come, adults and children can enjoy a variety of outdoor activities, our eyes can adapt to different light and dark environment. However, prolonged exposure to intense sunlight can increase the amount of harmful light entering the eyes (especially ultraviolet light), causing damage to the eyes. In these cases, wearing good quality sunglasses is the best way to protect your eyes.
Children's sunglasses are not decorative, and if the eyes are damaged, the child's vision may be affected forever. If children wear substandard sunglasses, the pupil will be dilated because of the lens blocking, the light flux into the eyes will increase, but because of its ultraviolet transmittance ratio than the visible light transmittance ratio is also high, it will produce serious damage to children's glasses, and even lead to keratitis, cataracts and other diseases.
When shopping for sunglasses, parents should try to choose framed children's sunglasses, and the color is not too dark, generally gray, teal, green is better. In addition, the child's lively nature is prone to collision and fall and other problems, the impact resistance of the glass lens is low, security is not high, it is recommended to choose resin, PC and other damage-resistant material glasses. When buying, parents can observe things in the distance through the sunglasses lenses, and at the same time rotate them slightly to see if there is any deformation, distortion and so on. If there is, it means that the lenses are deformed and should not be purchased.
Important markets such as the EU have adjusted their access thresholds for sunglasses in recent years. Since 2014, sunglasses exported to the EU region must comply with the mandatory safety requirements EN ISO 12312-1. Subsequently, the standard has been popularized to many countries around the world including Australia, Brazil, the United States and so on. Next April, a new version of the EU Personal Protective Equipment (PPE) regulation will become mandatory, once again raising the bar for distributors and manufacturers in terms of documentation and user information. At the same time, a new ISO standard for cycling/sporting sunglasses is also being drafted. For eyewear manufacturers, the barriers to entry in the global market are rising every year. TUV Rheinland Greater China's first -- and currently only -- eyewear testing lab opened in Shenzhen in early June, effectively reducing manufacturers' time and costs for testing and certification and helping sunglasses companies quickly enter the global market.
