Hong Kong's Consumer Council tested 17 models of ready-to-wear reading glasses and found that more than half failed to label pupillary distance, a key measurement needed to align lenses properly. Pupillary distance—the distance between the centers of a person's pupils—is essential for ensuring clear vision and reducing the risk of eye strain when wearing reading glasses.
The failure to include this critical specification on product labeling represents a significant gap in consumer information. Without knowing the correct pupillary distance, consumers cannot verify whether a particular pair of ready-to-wear glasses is properly aligned for their individual eye geometry, which can result in vision problems and discomfort during use.
The findings highlight potential issues with how ready-to-wear reading glasses are being marketed and sold to consumers in Hong Kong. The absence of pupillary distance information makes it difficult for buyers to make informed purchasing decisions and raises questions about whether these products meet appropriate labeling standards for optical devices.
