记者随机购买的10副太阳镜经检测后暴露出严重质量问题[1]。其中仅1副合格，6副完全没有标签，2副标签标注不明确，1副标签与实测数据不符被判不合格[1]。这些劣质产品充斥市场，消费者防不胜防。
产品标识缺失背后是生产厂家的成本考量。生产厂家销售人员坦言"几毛钱的眼镜，我怎么做得出来UV400的样式"，并表示"可以贴"合格证即使产品不符合国标[1]。根据国家标准GB39552.1-2020，太阳镜应标明产品名称、商标、生产厂名和厂址、执行标准、镜片分类号等信息，但这些要求在市场上普遍被忽视[1]。
镜片分类不当使用带来的安全隐患同样令人担忧。太阳镜分为5类，其中CAT4类透射比为3%-8%，属最高等级[1]。南京市产品质量监督检验院主任刘宝指出，"如果佩戴了4类太阳镜驾驶，穿越隧道时视线会瞬间变得非常暗，很容易引发安全风险"[1]。消费者反馈也印证了这一问题，购买者时女士表示"刚戴上的时候眼睛有一点晕的...到晚上回去的时候，眼睛更不舒服了"[1]，另一位消费者李先生则直言"戴上基本上就看不清了...一片漆黑"[1]。
A journalist investigation has uncovered serious quality control issues in the sunglasses market, with counterfeit labeling and substandard materials posing potential risks to consumer safety and eye health.[1] Among ten sunglasses randomly purchased for testing, only one met quality standards, while six lacked any labeling whatsoever, two contained unclear or misleading labels, and one bore a label that contradicted its actual performance measurements.[1]
The investigation found that manufacturers deliberately cut corners to reduce production costs, with sales representatives openly acknowledging they use inferior materials and fraudulently apply quality certifications.[1] According to statements from factory personnel, products costing only a few cents cannot genuinely meet UV400 standards, yet manufacturers still affix compliance certificates regardless.[1] Retailers demonstrated insufficient knowledge of product specifications, unable to provide consumers with accurate information about the eyewear they were selling.[1]
China's national standard GB39552.1-2020 mandates that sunglasses undergo over twenty testing parameters and must display essential information including product name, trademark, manufacturer name and address, applicable standards, and lens category classification.[1] Sunglasses are classified into five categories based on light transmittance: CAT0 and CAT1 (transmittance above 43%), CAT2 (18%-43%), CAT3 (8%-18%), and CAT4 (3%-8%), each suited for different usage scenarios.[1] According to Liu Bao, director of the Nanjing Product Quality Supervision and Testing Institute, wearing category 4 sunglasses while driving creates significant safety hazards, as vision becomes extremely dim when entering tunnels, potentially triggering accidents.[1]
Consumer feedback revealed immediate adverse effects from wearing substandard sunglasses. One purchaser, Ms. Shi, reported experiencing dizziness upon first wearing the product, with discomfort intensifying by evening.[1] Another consumer, Mr. Li, described the purchased sunglasses as rendering vision nearly impossible, describing the effect as pitch black.[1]
