Lens Technical Committee Meeting AgendaVEE 2019 – Thursday March 21, 2019 – 11pm – 1pmChairperson – Dick Whitney (Carl Zeiss Vision)Vice Chair Elect – Greg Williams (Colts)LTC Mission StatementThe Lens Technical Committee is a forum open to interested Vision Council members dealing with any technical issuepertaining to the manufacture, marketing, or distribution of spectacle lenses globally. When needed, the LTC may wish torequest Division leadership to form task forces or committees to study lens issues in further detail. Participants must beVision Council members to regularly participate, and discussions shall be directed toward areas of benefit to improvingthis field and not to benefit one company or individual.1) Administrative Remarkso Welcome / IntroductionsThe meeting began at 11:05 AM.

Given that Keith Cross is now Lens Division Chair, it was deemedappropriate that a new Vice Chair be appointed. Keith was thanked for his service,having served as Vice Chair since 2011.Action:Dick Whitney asked those present to confirm Greg Williams as Vice Chair. Greg wasunanimously approved. Congratulations Greg!2) Discussion of LTC format / meeting contentWith the change in Vice Chairmanship, is was thought it was a relevant time to reviewthe meeting content and format. Both Dick and Greg are open to changes and would liketo keep the discussions interesting and relevant. While Standards and Regulatoryupdates are a central point of interest to LTC members, they would welcomesuggestions on what information is of interest to the group.Dick noted that since he began chairmanship in 1997, the organization (The VisionCouncil) and LTC makeup have changed significantly. At that time, the organization wascalled the OMA (Optical Manufacturers Association). As the Industry evolved, the OMAbecame the OIA (Optical Industry Association). This changed to the VCA (Vision Councilof America) and finally The Vision Council. These name changes reflect how themakeup of the LTC has changed.3) Overview of past achievements with an eye toward future projectsDick provided an overview of topics/projects that have been tackled by the LTC. In manycases the work was first initiated by the LTC. The purpose of doing so was to educate onhow several achievements began with the LTC. Additionally, it was hoped that such adiscussion would provide a forum for new ideas and areas of work. He also took thistime to comment on aspects of several of the topics.Abrasion Resistance testing and compliance to the FDA Impact Regulation were topicsthat were covered for decades. Both topics have matured, but education on key aspectsof both are periodically warranted. Other topics listed are examples of initiatives thatbegan at the LTC.2

Action: A new topic was proposed for work (See item 7) and Lens Division approvalsubsequently granted for “Enhanced Single vision” work.4) Regulatory Update – Michael Vitale / Rick Van ArnamMichael Vitale and Rick Van Arnam gave a summary of Standards and regulatory affairs.Excerpted below are portions of their presentationsCalifornia Prop 65 SUD Efforts December 2, 2016, TVC submitted an SUD application to OEHHA for BpA in our membersproductsTesting occurred on 129 eyewear samples across a variety of eyewear categories– Prescription and Sunglass lenses,– Ophthalmic and Sunglass frames,– temples,– safety eyewear– nose padsResults showed total BPA content in these samples ranged from not detected (“ND”) 15 parts perbillion (“ppb”) to only 302 parts per million (“ppm”), with a vast majority below 10 ppmWhen tested using an artificial perspiration extraction method, not one of the 129 eyewearsamples showed any migration of BPA from the samples ( 15ppb) Toxicology testing reported; If BPA migrated into the artificial perspiration at the detection limit, the theoreticalestimated exposure posed by the BPA is significantly less than the Maximum AllowableDose Level (“MADL”) of 3 micrograms per day (“μg/day”) and a BPA concentration of 302ppm in eyewear does not result in a detectable exposure to BPA Asked OEHHA to issue a completeness determination of our SUD application in early 2017 The updated SUD application was submitted on 7/17/2018 Our application was deemed complete on 3/8/2019!!!3

Once a SUD application is deemed complete then no NOVs can be filed against theproduct category in question Next Steps––Approximately 60 days for determination?In the meantime, continue to label!!!Also, please remember, this application is for BpA and not any otherchemicals that may be in your products!UDI Update Class I compliance date now 09/24/2020 Both labeling and GUDID participation Are you taking steps to be ready for this?Lens manufacturers and optical labs exemption granted Both labeling and GUDID participation Request for frames exemption still pending Both labeling and GUDID participation Based on similarity to lens argument and analysisStatus of US/ China Trade war Negotiations with China still ongoingAdditional 10% duty still remains on Chinese origin eyeglass cases, lens cleaningsolutions and magnifiers;– Decision to increase from 10% to 25% on hold; no new target date announced.Additional 25% duty still remains on certain optical production machinery, ophthalmicinstruments, and electro-diagnostic equipment.Rx lenses, frames, plano sunglasses, reading glasses, goggles, and most low vision stillunaffected. But this could change if negotiations fail.When will the trade war end, and what happens then to the increased duties?– Hopefully, US and China will walk back the increased duties.5) ANSI Z80.1 – 2015 (Rx) Feb 2019 meeting updatea) ANSI Z80.1 – 2015 (Rx)The committee is progressing well toward completion of a 2020 revision to ANSI Z80.1 -2015.Of specific interest to the LTC is in the area of product claims which are planned to be added forTransmittance. Work is being done in parallel with ANSI Z80.3 Sunglass to include. This is alsobeing shared with ISO 8980-6.oTransmission claims–Two areas for product transmittance claims have been addressed and are planned for thenext revision.1) Claims for attenuation for short wavelengths 380nmThe committee tentatively agreed to the proposed 2% value to define themaximum value for the wavelength for cutoff claims.2.) Claims for selective transmittance attention in visible range.If a manufacturer is claiming attenuation, the following is to besupplied:1.)Range of wavelengths attenuated4

2.)Amount of attenuation within that range3.)Whether values are spectral or weightedDick Whitney reported that these were communicated to the ISO 8980-6 in May andNovember during the WG group meetings and were favorably received.oBackside UV surface anti- reflection product claims - Rick Tinson raised the concernthat products that claim backside “UV” anti-reflectance are not covered by the standard.Dr. Citek was assigned a task to suggest a wording that would address this, perhaps byallowing the manufacturer to specify/provide supportive materials as requested.b) ANSI Z80.3-2015 – Sunglass StandardThe ANSI Z80.3 Sunglass standard is also proceeding with its revision for 2020. Adiscussion of the Traffic Signal recognition section took place. No plans at present tochange the requirement. A discussion took place questioning an aspect of min Tv of0.2%. It was noted this was added in 1997 when there was an issue with lack ofrecognition of an LED signal.c) ANSI / Frames meeting – Laurin Bianchi took over as chair of this committee. NickMileti assumed Vice Chairmanship of ANSI Z80 and therefore stepped down fromthis role.6) ISO updates8980-6 Claims meeting topics/issuesDick Whitney reported on the Transmission discussions and their apparent acceptanceby the claims group when they met in China in November. Another topic discussed atlength was the desire by China to determine the material refractive index withoutdestroying the lens. Alfredo Duenez did a study where he demonstrated the difficulty inback calculating index. One drawback identified was that accurate curve measurementfor his samples was not possible as AR coated lenses are difficult to measure. Hissurface power gage measurements were not accurate enough, and thickness correlationwas insufficient to distinguish index categories.Abrasion TR – SO DTR 21958:2018(E)The work of the ISO Abrasion TR was completed and published. Neil Roche was projectleader and was able to complete this work at the end of last year.7) New BusinessEnhanced Single Vision Lenses – Pete HanlinPete Hanlin (Essilor) had asked to discuss the topic of “Power Boost” lenses during the LTC. Thistopic was raised at the last ANSI Z80.1 meeting and this discussion was a follow up to that. Petewas not able to attend the LTC and therefore Michael Vitale spoke on Pete’s behalf.Power Boost lenses are confusing to the market and there are some states that will not allow anOptician to dispense them without the okay from the prescribing doctor. Those states are claimingthat the Optician would then be prescribing an add power and that they are not authorized to do5

so. Pete wanted to set up a task force to investigate this and the LTC agreed we would bring it upto the Lens Division Leadership.Action following the LTC meetingSubsequent to the LTC Meeting, Michael Vitale asked the Lens Division leadership to authorize atask force to work on this topic. The Lens division agreed.Rick Tinson (Hoya), Pete Hanlin (Essilor), Michael Vitale (The Vision Council) Carrie Wilson(Walmart) and Brent McCardle (Zeiss) are presently identified as making up the task group whichreports into the LTC. The plan is for them to present their recommendations during our VEW2019 LTC meeting.8) Adjournment – The meeting was adjourned at 12:55PM.6

called the OMA (Optical Manufacturers Association). As the Industry evolved, the OMA became the OIA (Optical Industry Association) . This changed to the VCA (Vision Council of America) and finally The Vision Council. These name changes reflect how the makeup of the LTC has changed. 3) Overview of past achievements with an eye toward future projects
