Vision Council updates lens description standard
The Vision Council’s Lens Division, along with the Lens Product Description Standard Committee, has updated the Lens Description Standard to include changes in the color and filter categories.
The updated standard, Lens Description Standard v. 2.2, includes the addition of the color violet with a label of VIOn. The standard also added the high energy visible filter with a label of HEV, according to a press release from the Vision Council.
The Lens Description Standard can be used by manufacturers when describing the technical attributes of lenses, according to the release. To ensure accurate control of lens thickness during prescription processing, the standard provides a consistent method and vocabulary for describing the various types of lenses.
“The Lens Description Standard remains the leading industry tool for lens manufacturers in describing the technical attributes of lenses,” Michael Vitale, Vision Council’s senior technical director and Lens Division liaison, said in the release. “This standard allows suppliers of laboratory management software to accurately select and process prescription lenses and includes data describing the front surface geometry of non-spherical lenses to enable accurate control of lens thickness.”
