More than half of the reading glasses tested by Hong Kong’s consumer watchdog failed to label pupillary distance, a key measurement for aligning lenses to ensure clear vision and reduce the risk of eye strain.
The Consumer Council tested 17 models of ready-to-wear reading glasses between January and May, with the claimed magnifying power for all models at +2.50 dioptres – commonly known as 250 degrees.
Prices ranged from HK$8 to HK$490 (US$1 to US$62.50).
The watchdog’s results showed that although all models performed satisfactorily in terms of durability and wearer safety, most lacked the labelling and warning statements required under European standards.
Only seven models indicated their pupillary distance – a key measurement for comfort and visual alignment – or their optical centre distance. The brands included Guanhao, Haomenglai Glasses and several sold at stalls in Sham Shui Po.
The remaining 10 did not meet the standard requirement for permanent marking, making it difficult for consumers to choose suitable products, with the brands including Agoeyewear, Daiso and ones sold at home care supply chain JHC.
