The invention provides a lens in which the lens periphery is controlled as
to each of thickness differential and both the rate of change from
thinner to thicker regions and the shape of the transition from thinner
to thicker regions within each of the dual thin zones. The lens of the
invention substantially reduces the time for the lens' auto-positioning.
Additionally, the lenses of the invention maintain their on-eye
orientation better as compared to conventionally stabilized lenses.
