RX Programme

with High-Performance Colorboost™ Lenses

CHARMANT offers an innovative prescription lens programme for selected HEAD sunglasses. The prescription glazing is performed by Wetzlich Optik-Präzision GmbH, a German specialist in precision eyewear lenses with many years of expertise in developing high-quality vision solutions. At the heart of this collaboration are the contrast- and color-enhancing Colorboost™ lenses, designed specifically to meet the visual demands of active sports.

More Color, More Contrast, Visibly Better Performance

Colorboost™ technology expands the color spectrum perceived by the human eye — with measurable benefits:

  • Up to 35% more visible color compared to conventional lenses for a more vivid, sharper and more nuanced visual experience
  • A high Color Resolution Factor (CRF) enables finer color distinctions and more detailed visual signals
  • With a Color Accuracy Factor (CAF) of approx. 99%, colors appear almost true-to-life with minimal distortion
Colorboost™ lens technology enhances color contrast and expands the visible color spectrum with a high Color Resolution Factor (CRF) and Color Accuracy Factor (CAF).

Flexible & Powerful

Colorboost™ lenses can be adapted to a wide range of sport and vision requirements and are available as:

  • Single vision and progressive lens designs
  • Sport-specific tints
  • Optional combination with photochromic technology and polarized protection
