Patent ID: 7862171

Claim:
An ophthalmic lens element for correcting myopia in a wearer's eye, the ophthalmic lens element having a front surface, an optical axis, and an optical centre, the ophthalmic lens element including: (a) a central zone providing a first optical correction for substantially correcting myopia associated with the foveal region of the wearer's eye, the central zone comprising an area for supporting central vision over an angular range of eye rotation about the optical axis; and (b) a peripheral zone surrounding the central zone, the peripheral zone providing a second optical correction for substantially correcting myopia or hyperopia associated with a peripheral region of the retina of the wearer's eye; wherein the mean surface power of the peripheral zone at a radius of 20 mm from the optical centre as measured on the front surface is at least +0.50 D relative to the surface power at the optical centre over an azimuthal extent of at least 270 degrees.
