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@ ANSI Z80.1@ and those covered within the ASTM F08.57 committee. 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 fashion eyewear@ and for the flammability and durability 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@ or to provide corrective prescriptions as defined in ANSI Z80.1@ or to provide protection for selected sports as defined within ASTM F08.57 committee standards@ or to provide protection when making direct observation of the sun@ such as for viewing a partial or annular solar eclipse. Lenses covered by this standard are not intended for use under conditions of reduced illumination; however@ variable tint lenses that fade to a luminous transmittance greater than 75% are covered. Lenses with less than 75% luminous transmittance anywhere on the lenses are not suitable for driving under low light conditions@ such as but not limited to twilight or night
