This technology utilizes a floating thermoplastic rubber (TPR) element in the temples, providing comfort-enhancing compliance. Edge-Flex™ can stop pinching behind the ears while limiting slipping and reducing overall weight. What are AP+ Lenses?AP+ (Aqua Precision Plus) builds on the legacy of our long-standing Aqua Precision lens technology with a fresh take on color rendition. While both lens technologies improve visual clarity, we've fine-tuned AP+'s performance to deliver a unique viewing experience. AP+ lenses amplify red, orange, and green hues while remaining true to the clarity-improving foundation of our standard Aqua Precision lens technology. What is TPR?Thermoplastic rubber (TPR) is a compound that becomes tacky when exposed to moisture. It's utilized in Lassen's nose pads and Edge-Flex™ temples to limit slipping and improve comfort.
