A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.

Bifocal contact lens

A corneal reshaping by means of a soft contact lens to manipulate tear pressure gradient to produce a dimensional change to the surface profile of the cornea of the wearer to provide at least a temporary change in the refractive state of the eye eliminating the need for other refractive corrections. The contact lens has mechanical properties and/or a geometric shape such that when the lens is fitted to the eye the pressure applied to the eye via the lens will vary in a radial direction between at least one zone of higher pressure and at least one zone of lower pressure so that wearing the lens will over time cause a dimensional change to the surface layer of the cornea.
