CLICK HERE We offer our patented notches in two locations: Standard Notch and Terra Notch (named after our co-founder). The Standard Notch (pictured above) is designed to work with most wrap-around or sport style sunglasses, shooting glasses, and safety glasses. These styles have a curved appearance, designed to conform to the contour of the head. The Terra Notch is designed to work with most aviator or fashion style sunglasses as well as prescription eyewear. These styles are more squared off at the corners, causing the frame to sit further away from the face.
