Overview
ISO 16034:2002 - Ophthalmic optics - Specifications for single‑vision ready‑to‑wear near‑vision spectacles - defines minimum safety, optical and marking requirements for commercially supplied premounted reading spectacles (single‑vision near lenses). These ready‑to‑wear near‑vision spectacles are intended for short‑term near tasks (reading) and are not intended for regular use without approval from an eyecare professional. The standard helps manufacturers, suppliers and regulators ensure consistent quality and consumer safety for over‑the‑counter reading glasses.
Key Topics and Requirements
- Product definition: Ready‑to‑wear near‑vision spectacles with two uncut single‑vision lenses of positive equivalent power, supplied without an individual practitioner’s prescription.
- Optical power range: Nominal spherical powers between +1.00 D and +3.50 D.
- Power tolerances: Declared lens powers must meet tolerance requirements referenced to ISO 8980‑1.
- Prismatic tolerances: Prism measured at manufacturer‑specified reference points:
- Horizontal prism tolerance (per lens): 0.33 cm/m
- Vertical prism tolerance (difference between lenses): 0.33 cm/m
- Performance & assembly:
- Lenses must satisfy general finished lens requirements of ISO 14889.
- Frames and mounting must comply with ISO 12870, including the lens‑retention (holding) test.
- Tolerances apply at 23 °C ± 5 °C.
- Marking and packaging:
- Indelible marking on spectacles: manufacturer name or brand and declared spherical power (diopters).
- Packaging/labelling must include declared binocular (interpupillary) distance in mm.
- Required warning label and symbol indicating not suitable for driving or road use, not for distance vision, and not a substitute for professional eyewear or protective eyewear.
Applications and Who Uses This Standard
- Manufacturers of ready‑to‑wear reading spectacles use ISO 16034 to design and certify products that meet international safety and optical quality benchmarks.
- Quality assurance and testing laboratories refer to the standard for inspection, measurement and acceptance criteria (power, prism, lens retention).
- Retailers and distributors use the marking/packaging requirements to ensure compliance and provide correct consumer information.
- Regulators and standards bodies adopt ISO 16034 to harmonize market surveillance, import controls and consumer safety rules.
- Opticians and eyecare professionals refer to the standard when advising patients about over‑the‑counter reading spectacles and when recommending professional alternatives.
