4 BASE LENS CURVE
Lens 'Base Curve' is a measure of the front curvature of the lens. The higher the number, the greater the curve. 4 and 6 base lenses are generally flatter across the front. 8 base lenses have a greater curve for a more 'wrapped' look.

HANDMADE ACETATE FRAMES
Made with premium quality acetate (originating from renewable resources wood pulp & cotton fibre), the ideal material for making durable eyewear.
