A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

An eyeglass device including a variable transmission ophthalmic lens, a method for driving the transmission of such lens, and a non-transitory computer-readable storage medium for implementing such method. The eyeglass device comprises a light sensor configured for measuring an amount of light in the environment of a wearer and a controlling circuit configured for receiving at least light data from said light sensor and for driving the transmission of said ophthalmic lens on the basis of said light data. The controlling circuit is configured for driving the transmission of said ophthalmic lens on the basis further of movement data, said movement data being derived from an estimation of a movement of the wearer's head.

A method for user authentication is disclosed including capturing involuntary eye movement of an eyeball of a user; generating a unique pattern to identify the user in response to the involuntary eye movement; storing the unique pattern into a secured non-volatile memory device; and authenticating the user with an electronic device in response to the stored unique pattern.

A method and apparatus is disclosed for artificially creating space within a lens such that, when an image is projected from the lens onto the retina of the user, the image appears to be positioned further away than it actually is. This is accomplished by embedding a series of projection tubes on the perimeter of a lens adapted to project an image inward toward the retina of the user. The projection tubes will provide artificial spacing and cause the projected image to seem distant or otherwise positioned further away, creating a more realistic viewpoint for the user.

Eyewear having one or more electronic devices stowable and deployable from storage cavities disposed in one or both temple arms of the eyewear are described. The devices are deployable through passages in the eyewear frame which are covered when the devices are in the stowed position. Devices may be changed either by removing and replacing a device or by removing and replacing a temple arm on a particular set of eyewear.

A display apparatus for wearing over corrective eyewear has a frame structure that supports left- and right-side protective lenses, wherein each protective lens has a rear surface disposed to face toward the corrective eyewear, and a front surface disposed to face the outside-world object scene. A bridging member is hinged to the frame between the left- and right-side protective lenses, wherein the bridging member extends a nose bridge engagement member toward a viewer nose position, wherein the bridging member further has a coupling configured to removably suspend at least one output element of an electronically energized display system over the front surface of the left- or right-side protective lens.

A contact lens has a core thick enough to accommodate a payload. The lens further has outer and inner coverings that cover parts of the core. Each covering is a thin layer of gas-permeable material shaped to form a respective cavity between the covering and the core. Oxygen passes through the outer covering to the outer cavity, through an air path within the core to the inner cavity, and through the inner covering to reach the cornea of the wearer's eye. To increase oxygen flow, a patterned structure is formed at an interface between the core and at least one of the outer and inner covering, comprising supports at which the core and covering contact, and recesses forming the cavity between the core and covering for oxygen flow. The outer and inner coverings may be made from different types of gas-permeable materials having different levels of gas-permeability and brittleness.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.

A disposable sleeve having an antimicrobial property for covering an arm of a pair of spectacles is presently disclosed. The disposable sleeve comprises a generally tubular body having an opening at least one end thereof for receiving the spectacle arm, and at least one antimicrobial agent containing component applied to a surface of the tubular body and/or dispersed therein to impart the antimicrobial property thereto.
