Cleaner, Safer Lens Crafting

Wisconsin Vision has the nation’s first alloy-free lens lab.

Wisconsin Vision is committed to using environmentally-friendly methods for prescription lens manufacturing. Our lens lab – LBC Optics in New Berlin, WI—is the first in North America to use the innovative CCB Modulo from German equipment manufacturer Schneider Optical Machines.

Our investment in alloy-free technology makes prescription eyewear from Wisconsin Vision safer, greener, and better for our employees and our patients.

What is alloy and why avoid it?

Aluminum alloy is a mix of metals used to block (securely mount) unfinished lens material during grinding and polishing. Alloy contains hazardous materials including cadmium, lead & indium.

Alloy has long been the blocking material of choice for most lens labs, because it provides strong support during the dynamic lens surfacing process. But using alloy comes at a high cost:

  • Alloy and its fumes are a health hazard for optics industry workers
  • Alloy is bad for the environment and difficult to dispose of safely
  • Alloy is expensive, with unpredictable price fluctuations

The vast majority of optical companies still use alloy during eyewear prescription processing. Wisconsin Vision is the first optical retailer in the USA to use an alloy-free process. We have completely eliminated alloy in our lens lab by investing in the latest eyeglass lens technology.

Wisconsin Lens Manufacturer

A big step forward for Wisconsin

Federal agencies including the EPA, OSHA & the CDC have targeted alloy material for increased restriction and eventual eradication. Years or even decades from now, it’s likely alloy will be banned from use.

Wisconsin Vision is ahead of the curve, leading the way forward in cleaner, greener lens surfacing. Learn more about Wisconsin’s largest independently-owned optical company and our commitment to giving back to our community:
