39CIG – GUAVA LENS - A Red/Green Deficient Design Study.  
Infused with Spectral Pigment Accelerators.  
THE NEW ZEISS PILLA “SPA” LENS TECH - CGR R/G Filter Blueprint
The introduction of our CGR technology with a focus on helping red/green colour deficiency has been a run-away success. The 38CIG filter used the basis of the CGR platform without the polarisers for the initial lens design study. With the Zeiss team, we took the technology in the CGR RGLL and RGHL and articulated this spectral curve into a new lens design. The result is a fantastic all-around lens that is both designed for helping those with Red/Green deficiency but also works extremely well for all shooters looking for more bump in the target if you have an affinity for more red in the lens. If you like lenses that have more red in them without the sight picture being too intense in red, this is a super balanced lens with an intense sight picture.
The lens has our proprietary 7-Layer anti-reflective applied to reduce light dispersion to near zero.
