Acetate temples with inner bendable cores provide a customizable fit. Spring hinges with a measured flex rate provide gentle retention to keep the eyewear in place. Precision designed metal hinge block creates the engineered stability and function for long-term wear. For anyone who appreciates design, the HAUS is truly built.
