This standard applies to all nonprescription sunglasses and fashion eyewear@ normally used for casual@ dress@ and recreational purposes@ having lenses of substantially plano power. This standard specifically excludes products covered by ANSI Z87.1-2003@ ANSI Z80.1-2005@ ASTM F803-2003@ and high-impact resistance eyewear designed exclusively for designated sports use. Sunglass needs for aphakics may not be met by this standard. Purpose The purpose of this standard is to establish standards for noncorrective (essentially plano power) lenses that are intended for attenuation of light and for fashionwear@ and for the flammability of frames and lenses. These products are commonly called sunglasses@ and they are not designed to be industrial safety eyewear as defined in ANSI Z87.1-2003@ or to provide corrective prescriptions as defined in ANSI Z80.1-2005@ or to provide protection for selected sports defined in ASTM F803- 2003. Lenses covered by this standard are not intended for use under conditions of reduced illumination@ such as for night driving; however@ variable tint lenses that fade to a luminous transmittance greater than 75% are covered.
