The invention provides methods for designing contact lenses and contact lenses designed according to the method, which lenses provide an improved method for presbyopia correction compared to conventional lenses and methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by using lens pairs that act synergistically to provide the lens wearer with good binocularity and consistent performance in near, intermediate and distance vision.

Lenses for the correction of presbyopia and methods of designing the lenses

The invention provides contact lenses which have improved dynamic stabilization and that utilize one or more thin zones in the lens' periphery.

Methods for rotationally stabilizing contact lenses

The invention provides lenses contact lenses which have improved dynamic stabilization and that utilize one or more thin zones in the lens' periphery.

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.

Rotationally stabilized contact lenses

The invention provides lenses in which peak pressure under the lens wearer's eyelids is reduced. The invention provides lens designs that reduce or eliminate mechanical chaffing of the cornea even in lenses made of high modulus materials.

Methods for reducing corneal staining in contact lens wearers

The invention provides methods for designing lenses useful for correcting presbyopia, lenses incorporating such designs and methods for producing these lenses. The lenses of the invention exhibit a better distribution of the distance and near vision powers within the multifocal zone and, thus, improved visual acuity and wearer satisfaction.
