6 Base Curvature - The base curvature corresponds to the curve of the lens. The higher the number, the higher the curve. 6 base styles have a “flatter” look. 8-9 base curves hug closer to the face. Lens Type
Spherical Lenses - Constructed from sections cut from a spherical surface. Spherical lenses have a constant curvature across all sections of the lens.
Polycarbonate - Made of the toughest, most shatter resistant material. Light, comfortable and much more impact resistant than glass lenses.
