Colorboost Proposes CRF and CAF Metrics to Quantify Lens Color Performance

US optical technology company Colorboost, expanding into Europe, has proposed two new metrics—the Color Resolution Factor (CRF) and the Color Accuracy Factor (CAF)—to objectively measure lens color performance. The initiative addresses a gap in industry standards where terms like “enhanced color” lack shared measurement methods, unlike established values such as Visible Light Transmission. Adapting display industry concepts, Colorboost maps pixel density to Spatial Cutoff Frequency to define these factors. CRF serves as the primary measure of color contrast, comparing a lens’s ability to resolve color differences against a clear reference. This approach aims to standardize how wavelength-filtering lenses are evaluated, moving beyond simple light blocking to quantifiable visual enhancement.
