Abstract
An ophthalmic lens includes a lens material having two curved surfaces opposing each other; a light scattering region; a first aperture (e.g., clear or with reduced scattering density/power compared to the light scattering region) surrounded by the light scattering region; and a second aperture (e.g., clear or with reduced scattering density/power compared to the light scattering region) separated from the first clear aperture by a portion of the light scattering region.
Claims17
An ophthalmic lens, comprising:
- a lens material having two opposing curved surfaces, the curved surfaces defining a lens optical axis perpendicular to a first of the curved surfaces where the lens optical axis intersects a first curved surface of the curved surfaces;
- a light scattering region comprising light scattering centers, the light scattering region being defined by a first continuous portion of the lens in which the light scattering centers are spaced apart from each other by 2 mm or less;
- and
- an elongate, clear aperture that is decentered from the lens optical axis and completely surrounded by the light scattering region,
- wherein the clear aperture is defined by a second continuous portion of the lens different from the first continuous portion, the second continuous portion being free of the light scattering centers.
