Abstract:
An ophthalmic multifocal lens to be worn on or in a human eye. The lens has an optical portion with anterior and posterior surfaces and a circumferential peripheral boundary. The optical portion has far vision zones having a first refractive power and near vision zones having an add power. The far visions zones and near vision zones include ring segments having one of the refractive powers each radially bounding a more central zone of another one of the refractive powers. The ring segments include ring segments bordering on the peripheral boundary and alternating in circumferential sense along the full circumference of the peripheral boundary.
