The Vision Council announced that the American National Standards Institute has published the 2015 revision of Standard Z80.1, Prescription of Ophthalmic Lenses – Recommendations.
This standard applies to all prescription spectacle lenses in unfinished and finished forms and serves to guide optical laboratories and opticians/dispensers, according to an announcement from the Vision Council, the secretariat administrator for the Accredited Standards Committee Z80 for the American National Standards Institute (ANSI).
“The 2015 revision of Standard Z80.1 supersedes the 2010 standard and represents 5 years of work by a team of 22 industry experts led by chairman Dick Whitney of Carl Zeiss Vision, vice chair Rick Tinson of Hoya Vision Care and secretary Karl Citek, OD, PhD, representing the American Optometric Association,” according to the Vision Council’s press release.
Specifically, the new standard provides updates to “better reflect how the committee believes the standard should be used in today’s environment, “position of wear” definitions, clarification of how tolerances should be applied to compensated lenses, modifications to marketing guidelines, a recommendation for minimum transmittance when driving and addition of a reference to orientation of polarization, the release stated.
