US voluntary industry standard for sunglasses has been revised and includes clarification of concepts and principles, as well as closer alignment with applicable provisions in other US and international standards.

In December 2015, the US ANSI Z80.3 standard for sunglasses was updated from the 2010 version to the current 2015 version.

This revision incorporates a continued effort to more properly explain and clarify concepts and principles, and to more closely align requirements of this standard with similar relevant provisions in existing US and international standards.

In addition to minor typographical corrections, changes include:

  • Prism power and imbalance are now defined only for finished products in the as-worn position, since lenses with high base curves and/or significant faceform (wrap) angles must include the proper compensating prism in the lens blanks to ensure minimal prism in the final product.
  • Luminous transmittance variations and tolerances are now provided in units of percent rather than density.
  • Definitions of reference point, special purpose lenses, and polarization axis tolerance are added.
  • Minimum luminous transmittance of gradient tint lenses is modified.
  • A figure demonstrating assessment of cosmetic lens quality is added.
  • Procedure for assessment of frame flammability is amended.
  • Finally, new requirements for frame durability, such as corrosion, material safety, and deformation, which already exist in other standards, are added.
