Over half of tested reading specs fail to list key details to prevent eye strain

Consumer Council tested 17 models of ready-to-wear reading glasses between January and May this year
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 reduced risk of eye strain.
The Consumer Council tested 17 models of ready-to-wear reading glasses between January and May this year, with the claimed degree of presbyopia for all models being +2.50 or +2.5 dioptres – commonly known as 250 degrees.
The product prices also ranged from HK$8 to HK$490.
The watchdog’s results showed that although all models performed satisfactorily in terms of mechanical strength and stability, resistance to ignition, nickel release and drop tests, most lacked the labelling and warning statements required under European standards.
Among them, only seven models indicated their pupillary distance – a key measurement for comfort and visual alignment – or optical centre distance (OCD). 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 such brands including Agoeyewear, Daiso and those sold at home care supply chain JHC.
“If the pupillary distance of the lenses does not match the wearer’s pupillary distance, the lenses cannot align accurately with the pupils. This creates unnecessary prism effects,” the council said in a statement.

Executive Summary

A consumer watchdog tested 17 models of ready-to-wear reading glasses between January and May of the current year. The testing focused on whether the products included key details to prevent eye strain, specifically pupillary distance measurements. Most of the tested glasses lacked the required labeling and warning statements mandated by European standards. Of the seventeen models examined, only seven indicated pupillary distance or optical centre distance, which are crucial for proper lens alignment and visual comfort. The testing also confirmed that all models met mechanical strength and stability criteria, and passed tests for resistance to ignition, nickel release, and drop. Product prices ranged significantly, from HK$8 to HK$490.

Full Take

The discrepancy between mechanical compliance (strength, stability) and informational transparency (pupillary distance labeling) reveals a systemic failure in product disclosure designed to prioritize sales over user safety. The existence of seven models providing essential spatial data while the majority lack it establishes a clear asymmetry: some products are transparent about crucial optical alignment metrics, while others operate in an opaque space where consumers risk inducing discomfort through unmeasured prism effects. This suggests that compliance with aesthetic or manufacturing standards does not automatically translate into compliance with ergonomic or safety standards when regulatory oversight is weak. The varying range of prices further complicates the analysis, implying that transparency may be correlated with the cost tier of the product. The pattern observed is a choice between superficial compliance and functional integrity driven by market pressures. The immediate implication for consumer agency is that navigating the market requires an active counter-effort to seek out information that standard testing protocols overlook. What factors drive manufacturers to withhold spatial data, even when basic safety tests are passed? How can regulatory bodies mandate the inclusion of non-essential but critical ergonomic metrics to shift the default expectation from mere legality to genuine user-centric design?
