摘要:
An ophthalmic lens incorporating an array of microlenses. In order to refract light, the common denominator in conventional ophthalmic lenses is the difference in curvature between the front surface and the back surface. However, this poses certain limitations in the design of certain high-end lenses such as prescription sunglasses and progressive lenses. In the case of prescription sunglasses, such design limitations result in prescription sunglasses typically only being available in a limited range of prescriptions. The choice of the curvature of the front surface of the lens (base curve) is determined by the geometry of the frame that wraps around the face. Most prescription sunglasses must, therefore, be made using base curves in the range of six to eight diopters.
