What is ISO 185261 about?
ISO 18526 discusses eye and face protection. ISO 185261 is the first part of the multi-series ISO 18526. ISO 185261 specifies the reference test methods for determining the spherical, cylindrical, and prismatic refractive power properties of unmounted and mounted Plano lenses (non-corrective lenses) for eye and face protectors.
Note: ISO 185261 does not apply to any eye and face protection product requirement standards for which other test methods are specified.
Who is ISO 185261 for?
ISO 185261 on eye and face protection test methods is useful for:
- Manufacturers of eye and face protectors
- Eyewear manufacturers
- Quality control personnel
- Design engineers
Why should you use ISO 185261?
Plano lenses are designed to protect against eye injuries caused by flying dust, dirt, metal, wood chips, and other particles. Any errors in the refractive power properties of unmounted and mounted Plano lenses can cause harm to the user. ISO 185261 provides a test to assess the spherical, cylindrical, and prismatic refractive power properties.
ISO 185261 provides you with geometrical optical test methods which include test methods for refractive power and prismatic power for Plano lenses. ISO 185261 also includes test methods for the prism imbalance of complete eye protectors or lenses covering both eyes. ISO 185261 also provides tests for spatial deviations.
ISO 185261 helps you to manufacture eye and face protectors that don’t distort the user’s vision.
