| titleOfInvention | Multifocal optical lenses |
| abstract | A multifocal ophthalmic contact lens (10.11) having a front surface (13), a rear surface (15) and an optical axis, comprising: a central optical zone (201b, 201f) in a central part of the lens , wherein the light entering the front surface of the lens is focused by the central optical zone (201b, 201f) in a direction parallel to the optical axis at a first focal point within 2.5 ° of the optical axis; a peripheral near vision optical zone (202b, 202f) located adjacent and radially outward from the central optical zone (201b, 201f), where the light entering the front surface of the lens and deviates from the optical axis with an angle of between 2 ° and 10 ° with respect to the optical axis is focused by the peripheral near vision optical zone (202b, 202f) in a direction not parallel to the optical axis at a second focal point between 2 ° and 10 ° with with respect to the optical axis, where the curvature of the front surface of the lens in the peripheral near vision optical zone (202f) is more inclined than the curvature of the front surface of the lens in the central optical zone (201f) between 4 and 10 diopters, or where the rear surface of the lens in the peripheral near vision optical zone (202b) is more inclined than the curvature of the rear surface of the lens in the central optical zone (201b) between 4 and 10 diopters, in C nde the first focal point and the second focal point do not overlap, where the lens is radially symmetric around the optical axis, where the central optical zone has a diameter between 0.4 mm and 0.6 mm, and where The peripheral optical zone extends radially outward on an annular diameter between 0.75 mm and 2.00 mm from the center of the lens. |
