The nose architecture is built to sit on the face reducing the eyes perceptive awareness of the nose. When the shooter is looking across the bridge, there is basically no interference. The frame is like a feather, weighing just 1 ounce. The 580 integrates the same Pilla signature “fork” temple tip found in the 560, made of a high performance rubber called “Megol”.

The 580 integrates a new lens anchoring system using “Shadow Boxing” on the lens edges. This open box design anchors the lenses and provides an extremely simple method of un-hooking the lens from the frame.
