适用范围
This Standard specifies the minimum requirements for complete ready-to-wear near-vision spectacles with positive power available directly to the public without the prescription of a licensed professional. Purpose The purpose of this standard is to establish requirements for ready-to-wear near-vision spectacles@ commonly called ??readers@?? and for the flammability and durability of frames and lenses. This standard does not address the safety performance requirements for occupational safety eyewear as defined within ANSI Z87.1 nor for sports eyewear as defined within ASTM F08.57 Committee standards. Requirements for physical and refractive properties@ except prismatic power imbalance@ are based on test methods and procedures described in ANSI Z80.1. Prismatic power properties and transmittance requirements in ANSI Z80.3 shall apply.
