351159220 | Astigmatic correction | 6 |
20130258276 | INCREASED STIFFNESS CENTER OPTIC IN SOFT CONTACT LENSES FOR ASTIGMATISM CORRECTION - A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error. | 10-03-2013 |
20140098338 | CONTACT LENS AND MANUFACTURING METHOD THEREOF - Provided is a contact lens having a novel structure with a high level of practicality which is easy to manufacture and apply to users, and can improve quality of vision (QOV). In an optical part of a contact lens, a spherical aberration of a size corresponding to a coma aberration of a user's naked eye, and of a size for which a spherical aberration of the user's naked eye will not be offset and will be made to remain is set as a corrective optical characteristic for a residual irregular astigmatism of the user's naked eye. A high-order aberration of the optical part is set rotationally symmetric around an optical axis. | 04-10-2014 |
20140268021 | METHOD AND APPARATUS FOR ENCAPSULATING A RIGID INSERT IN A CONTACT LENS FOR CORRRECTING VISION IN ASTIGMATIC PATIENTS - The present invention, as described above and as further defined by the claims below, provides methods for forming an Ophthalmic Lens that encapsulates a Rigid Insert, wherein the Rigid Insert may be tailored to correct specific astigmatic characteristics of an eye and apparatus for implementing such methods, as well as Ophthalmic Lenses formed with the Rigid Inserts. | 09-18-2014 |
20140320800 | DESIGN OF MYOPIA CONTROL OPHTHALMIC LENSES - Lenses are designed using the corneal topography or wavefront measurements of the eye derived by subtracting the optical power of the eye after orthokeratology treatment from the optical power before orthokeratology treatment. | 10-30-2014 |
20150362746 | TORIC LENS - A toric lens includes a first surface, a second surface, two first sector zones, and two second sector zones. The first surface and the second surface are opposite to each other. Each of the first sector zones has a first curvature on the first surface along a radial direction of the toric lens, and the first curvature is constant along an arc direction of the toric lens. The two second sector zones are alternately arranged with the two first sector zones. Each of the second sector zones has a second curvature on the first surface along the radial direction, and the second curvature is constant along the arc direction. The first curvature is steeper than the second curvature. | 12-17-2015 |
