After several years of joint development, OptoTech and ZEISS Vision Care are introducing a groundbreaking innovation in ophthalmic lens production: an eco-friendly manufacturing technology that replaces the conventional blocking process based on alloy or plastic adhesive.
OptoTech has developed two new key machines for this purpose: the fully automated IQ-Synergy Eco Blocker and the IQ-Synergy Eco Deblocker, with both systems already successfully tested and implemented at ZEISS Vision Care.
Benefits of Vacuum Blocking Technology
- Reduction in process steps, streamlining the manufacturing time
- Eco-friendly process that creates zero additional waste
- Flexible integration with existing machine fleet and blocking platforms
- Substantial cost and energy savings on consumables and machine operation
“With the ECO Block Technology, we are achieving several goals at once: making lens production faster, more cost-efficient, and above all, more sustainable,” says Dr. Stefan Seifried, Managing Director of OptoTech Optikmaschinen GmbH. “Together with ZEISS Vision Care, we have succeeded in creating a true milestone for the industry.”
