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.

The present disclosure is directed to devices and/or systems of modifying the incoming light through spectacle lenses that utilise at least one auxiliary or regional optical element, to provide extension or elongation of the depth of focus for a myopic eye. The disclosure relates to methods of correcting myopia and controlling or reducing the rate of myopia progression utilising extension of the depth of focus provided by the at least one auxiliary or regional optical element configured within, or in conjunction, combination, or juxtaposition with spectacle lenses. This disclosure relates to the use of an axicon, a light sword element, or a peacock eye element within the regional optical element or a sub-lens. This disclosure also relates to the use of a plurality of axicons, light sword elements or peacock eye elements configured within, or in conjunction, combination, or juxtaposition with spectacle lenses.

The present disclosure relates to a contact lens for managing myopia wherein the contact lens comprises of an optical zone about an optical axis and a non-optical peripheral carrier zone about the optical zone; wherein the optical zone is configured with a substantially single vision power profile providing correction for the eye, and a decentred second region configured with one or more meridionally and azimuthally variant power distributions, wherein at least one of the meridionally and azimuthally variant power distribution is devoid of mirror symmetry, the second region located substantially away from the optical centre and configured to provide at least in part a regional conoid of partial blur producing an optical stop signal for the eye; and wherein the non-optical peripheral carrier zone is configured with a thickness profile that is substantially rotationally symmetric to further provide a temporally and spatially varying stop signals to reduce myopia progression.

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.

Embodiments concern an intraocular implantable device operable comprising a disk-shaped 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.

A helmet attachment system is usable to attach a mandible or face or mouth guard. The helmet attachment system also comprises a pair of attachment bases, each arranged on a side of the helmet near to an ear covering of the helmet. The attachment bases each include a metal base plate covered by an attached body block. Each attachment base provides provisions for attaching opposite ends of a mandible to the bases. The metal base plate includes hooks for engaging an edge of the helmet. A pair of strap assemblies is provided, each strap assembly connected to one attachment base. The strap assemblies extend rearward and are connected to the back rail by a buckle member on the end of each strap assembly. The back rail includes a pair of buckle member-receiving slots. The straps assemblies and the hooks provided on the attachment bases secure the attachment bases to the helmet.

A contact lens for use in preventing or slowing the development or progression of myopia, and methods relating thereto, are described. The lens includes an optic zone comprising a central region having a first optical axis, and a curvature providing a base power, and centred on a centre of curvature that is on the first optical axis. The optic zone comprises an annular region, wherein the annular region surrounds the central region. The annular region comprises at least one maximum add power meridian having a curvature providing a maximum add power, and centred on a centre of curvature that is a first distance from the first optical axis. The annular region comprises at least one intermediate add power meridian, having a curvature providing an intermediate add power of between zero dioptres of add power and the maximum add power, and centred on a centre of curvature that is a different distance from the optical axis than the first distance.

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.

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 corneal 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.
