TurboFlex is a patented technology by the Aspex Eyewear group, for a unique hinge design. The hinges are able to rotate 360 degrees, so no matter how you twist or turn it, the temple of the frame will not break or snap off. The hinge provide durability and comfort even after the abuse that daily life can sometime provide on eyeglasses. These frames are ideal for children, keeping them safe from broken edges, and reducing the need to have the glasses constantly adjusted after being bent out of shape. No matter how you twist or turn it, our renowned TurboFlex® technology allows the temple of the frame to rotate 360° so it’s durable and comfortable.
