Devices and methods for measuring high order aberrations from an eye are described. A method includes obtaining information indicating one or more aberrations of an eye, and obtaining information indicating one or more of a visual axis of the eye, a center of a pupil of the eye, and a comeal vertex of the eye. The information from the optical device is used to modify a design of a contact lens so that a combination of the eye and the modified contact lens has reduced high order aberrations. In some cases, information indicating the orientation of the contact lens positioned on the eye is also used. The optical device may include an aberrometer; a first light source for providing first light toward an eye; a lens assembly for collecting light from the eye; and a first image sensor for receiving light that has been transmitted through the lens assembly.

Various embodiments of the present invention provide systems, methods, and processes for constructing a contact lens. In one embodiment, a contact lens assembly is provided, comprising: a curved polymer polarizer with an aperture; a lenslet disposed inside the aperture, wherein the lenslet enables imaging near objects; and a filter attached to the lenslet. In further embodiments, a method for fabricating a flexible contact lens is provided, comprising: fabricating an element having an extrusion; providing a front concave mold, wherein the front mold has an intrusion to accommodate the extrusion of the optical element; affixing the extrusion of the optical element to the intrusion of the front mold; attaching a back convex mold to the front concave mold, thereby forming a mold cavity; and filling the mold cavity with a pre-polymerized liquid, whereby upon polymerization, the pre-polymerized liquid forms the flexible contact lens and the optical element is partially encapsulated within the lens.

Embodiments concern an optical eye-contact device comprising a lens body having a symmetry axis and which further comprises a light-transmissive portion and an opaque portion, wherein the light-transmissive portion is decentered with respect to the symmetry axis.

The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens further improves upon an earlier method which utilizes and combines non-circularity and thickness differential aspects which results in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently. This further improvement of stiffness profile is achieved by optimizing and selectively addressing thickness differential both diametrically and circumferentially in a non-round lens design.

A helmet assembly includes a face shield and a single, center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position. The mounting arrangement can include a detent and two recesses, wherein the detent engages a first recess at a slightly forwardly displaced position to allow ventilation between the helmet and mandible and the face shield and a second recess at the tilted up, non-use position. The recess and detent engagement can be overcome by easy manual force acting on the face shield to reposition the face shield.

A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.

A computer-implemented method for providing a lens shape for an ophthalmic lens is disclosed. Further, there is provided a method for angular smoothing of a surface determined by carrier lines radially outwards of a prescription zone bordered by a first boundary line. In addition, there is provided an ophthalmic lens, in particular, a spectacle lens. Moreover, a method for minimizing the difference in thickness between two ophthalmic lenses for the same spectacles is provided. A computer program product and a machine-readable storage medium are provided as well.

Aspects of the disclosure provide for a method of creating a lens. Examples of the method include identifying a limbal zone of the eye, determining a back optic zone within the limbal zone, determining a front optic zone based at least partially on the limbal zone, computing a lens surface of the lens based at least partially on the limbal zone, the back optic zone, and the front optic zone, de-centering at least one of the back optic zone or the front optic zone from a visual axis or a spindle axis of the lens.
