METHOD AND DEVICE FOR ENSURING VARIATIONS OF SURFACE CONTACT WITH THE LOWER CENTURY AND HOLDING CONSTRUCTIONS UNDER THE CENTURY OF A VARIABLE MULTIFOCAL CONTACT LENS

摘要

1. A variable multifocal contact lens, comprising: a front surface and a rear surface, wherein said front surface and said rear surface comprise corresponding arcuate shapes and are connected at the edge of the lens; many optical zones; and the contact surface with the lower eyelid, the contact surface with the lower eyelid is configured to limit the amount of movement of the specified lens on the user's eye when the user changes the direction of view and the line of sight of the user moves from at least one optical zone to another specified optical zone. 2. The variable contact lens according to claim 1, which is a free-form lens formed peroxel. The variable contact lens according to claim 1 or 2, wherein the front surface comprises one or both of a contact surface with a lower eyelid and a retaining structure under the eyelid. The variable contact lens according to claim 1, wherein the contact surface with the lower eyelid comprises one continuous protrusion of the front surface portion extending inward laterally through said front surface of the lens. The variable contact lens according to claim 3, in which the contact surface with the lower eyelid is placed directly above the adjacent holding structure under the eyelid. The variable contact lens according to claim 1, wherein the contact surface with the lower eyelid is placed directly above the adjacent edge of the lens. The variable contact lens of claim 1, wherein the surface of the con
