Abstract: An ophthalmic lens that includes a lens material having two opposing curved surfaces, the curved surfaces defining a lens axis; and a light scattering region surrounding a clear aperture. The clear aperture and the light scattering region are substantially centered on the lens axis, and the light scattering region has a plurality of spaced apart scattering centers (e.g., on a lens surface and/or embedded in the lens material) sized and shaped to scatter incident light, the scattering centers being arranged in a pattern that includes a random variation in spacing between adjacent dots and/or a random variation in dot size.

Abstract: A method of making a contact lens includes providing a cylindrical blank for the contact lens, the cylindrical blank including a first portion and a second portion. The first portion is formed from a homogenous, optically clear material and the second portion is formed from an inhomogeneous, optically-scattering material. The method includes shaping the cylindrical blank to provide the contact lens. The contact lens includes a first region surrounded by a second region, the first region being formed from the homogenous, optically clear material and the second region being formed from the inhomogeneous, optically-scattering material.
