Abstract
The invention provides contact lenses with off-axis bevels. The bevels aid in increasing stability of the lens on the eye and form a smooth junction with the lenticular zone of the lens.
Claims22
A contact lens comprising a concave and a convex surface, at least one of the surfaces comprising one or more off-axis bevels and a lenticular zone adjacent to the off-axis bevel, wherein the junction between the lenticular zone and the bevel is a smooth junction.
A soft contact lens comprising a concave and a convex surface, the convex surface comprising a central optical zone, one or more off-axis bevels, and a lenticular zone adjacent to the off-axis bevel wherein the lenticular zone forms a smooth junction with the bevel.
A method for producing a contact lens comprising the step of providing a contact lens with a convex and a concave surface, one or more off-axis bevels on at least one of the surfaces and a lenticular zone adjacent to the off-axis bevel, wherein the junction between the lenticular zone and the bevel is a smooth junction.
A contact lens comprising a concave surface, a convex surface, a central axis, and a lenticular zone, at least one of the surfaces comprising one or more bevels that are rotationally symmetric sections of a torus and wherein the geometric center of the torus is located on the central axis of the lens and wherein the lenticular zone is adjacent to the off-axis bevel and the junction between the lenticular zone and the bevel is a smooth junction.
A method for producing a contact lens comprising the step of providing a lens with a concave surface, a convex surface, and a central axis, at least one of the surfaces comprising one or more bevels that are rotationally symmetric sections of a torus and wherein the geometric center of the torus is located on the central axis of the lens.
