A multi-zonal monofocal opthalmic lens comprises an inner zone, an
intermediate zone, and an outer zone. The inner zone has a first optical
power. The intermediate zone surrounds the inner zone and has a second
optical power that is different from the first power by a magnitude that
is less than at least about 0.75 Diopter. The outer zone surrounds the
intermediate zone and has a third optical power different from the second
optical power. In certain embodiments, the third optical power is equal
to the first optical power.
