Hi, great question. You can find an eye care practice with ZEISS technology by visiting www.zeiss.com/FindAnEyeDr You can then click the filter button and can filter by the ZEISS technology that you're looking for. Hope this helps!
Great question, here is the Singapore site. It looks like they do have these lenses, but you would need to contact an eye care provider to clarify. www.zeiss.com.sg/vision-care/eye-care-professionals/lenses/sun-protection-and-outdoor-lenses/sunglass-portfolio-and-tints/urban-outdoor-and-sun-lens-solutions.html
