The Vision Council has announced the publication of ANSI ASC Z80.1–2025, Prescription Ophthalmic Lenses – Recommendations, a revised technical standard governing prescription ophthalmic lenses in the United States.
Issued under the oversight of the Accredited Standards Committee Z80 (ASC Z80), the 2025 revision supersedes the previous 2020 standard and reflects five years of collaborative work by industry experts across ophthalmic manufacturing, optometry, and standards development.
The revision was led by ASC Z80 Chair Dick Whitney, Vice Chair Rick Tinson, Secretary Dr. Karl Citek, OD, PhD, representing the American Optometric Association, and Michael Vitale, ABOM, of The Vision Council, which serves as the Secretariat Administrator for ASC Z80.
According to The Vision Council, the updated standard incorporates a number of technical modifications and additions designed to ensure alignment with current industry practices and technological advancements. Key updates include clarified lens verification points, expanded descriptions of localized power errors, revised tolerances for claims related to visible light transmittance attenuation, new tolerances for prescribed prism, and a fully updated Optical and Mechanical Tolerances summary table.
ASC Z80 is the only body accredited by ANSI to develop national standards in the field of ophthalmic optics. Its scope includes prescription and non-prescription eyewear, contact lenses, ophthalmic instruments, and medical devices such as intraocular lenses and laser systems.
A copy of ANSI Z80.1–2025 is available for purchase through the ANSI webstore.
