Abstract:
An ophthalmic lens element includes an upper distance viewing zone and a lower near viewing zone. The upper distance viewing zone includes a central region with a first refractive power for clear distance vision and peripheral regions that are relatively positive in power compared to the first refractive power. The lower near viewing zone has a central region that is relatively positive in power compared to the first refractive power to account for accommodative lag. The powers of the peripheral regions of the lower near viewing zone are one of: i) equal to the power of the central region of the lower near viewing zone, ii) relatively positive in comparison to the power of the central region of the lower near viewing zone.
