Sunglasses standard analysis

u003cbru003eSunglasses not only have anti-ultraviolet, anti-glare and anti-glare effects, but are also a symbol of fashion. Nowadays, they have become one of the must-haves for mass consumers and occupy a very important position in the lives of modern people. . Because of this, the quality of sunglasses has attracted more and more attention from the society. As early as the 1970s, countries around the world have formulated relevant standards for detecting sunglasses. At present, the common testing basis for sunglasses exports are: European standard EN1836, American standard ANSI280. 3, Australian standard AS/NZS 1067 (currently valid versions are EN1836-2005+A1-2007, AN-SI280. 3-2001, AS/NZS1067 -2003), and for sunglasses sold in my country, they must comply with my country's glasses industry standard QB2457 (the current valid version is QB2457-2001), and the spectral performance part refers to the national standard GB10810. 3 (the current valid version is GB10810. 3- 2006). It can be said that the implementation of these standards has a very good supervisory effect on the circulation market of sunglasses, and effectively protects the rights and personal safety of consumers. However, at present, various countries have not reached an agreement on the quality of sunglasses, and there are still many differences in the testing basis of various countries, which undoubtedly creates unnecessary obstacles and barriers to the import and export of sunglasses. In view of the similarities and differences of these standards, some necessary analysis is of great significance to the production and quality control of sunglasses.
