A glasses/cap system for separably coupling glasses to a cap and for securing the glasses to the hat in either a usage orientation or a storage orientation. The coupling components mainly consisting of complementary magnets and ferromagnetic materials located in reciprocal parts of the glasses and cap alone or in combination with push type or bungee type connectors.

Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic function, and a wearable computer with optimal weight distribution and stretchable arms.

This invention relates to an ophthalmic lens comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered antireflective coating comprising a stack of at least one layer having a refractive index higher than or equal 1.5 and at least one layer having a refractive index lower than 1.5, such that:—the mean light reflection factor in the visible region R.sub.v is lower than or equal to 0.5% for an angle of incidence lower than 35°;—the Chroma C* is equal or higher than 18, preferably 20, according to the international colorimetric CIE L*a*b* for an angle of incidence (Θ) of 15°.

A pair of goggles with a lens assembly, a goggle frame, and at least one lens retention shelf is disclosed. The lens assembly includes a lens with a projection extending from the assembly. The goggle frame is made of a first material and has a frame aperture sized large enough to receive the projection from the lens assembly through it. The lens retention shelf is made of a second material harder than the first material and is disposed behind the frame. The first lens retention shelf includes a projection connector corresponding to the projection, the projection connector is aligned with the frame aperture and sized to receive and engage the projection with the goggle frame interposed between the lens retention shelf and the lens.

An eyewear retention apparatus is configured for use with an eyeglass frame having a pair of temples, each temple having a first extremity configured to attach to a lens holder and a second extremity configured to rest behind an ear of a wearer. The eyewear retention apparatus includes a strap formed of a flexible material and having a length extending between first and second ends, wherein each of the first and second ends includes a first hole extending through the strap. The eyewear retention apparatus also includes first and second fittings, each of the first and second fittings includes an end region having an opening configured to receive a respective one of the second extremity of the pair of temples and a tab having a second hole. The eyewear retention apparatus further includes a fastener extending through the first hole and the second hole.

Eyewear configured to retain a hat on a wearer's head is described herein. In one aspect, eyewear includes spectacles configured to be worn over eyes of a wearer. The eyewear also includes an elastic headband configured to fit around a head of the wearer. The elastic headband is attached to the spectacles. The eyewear includes two or more headgear retention devices attached to the headband and configured to be removably attached to a hat when the hat is worn on the head of the wearer and the headband is worn around the head of the wearer.

A slip-resistant eyewear system comprising an eyewear frame generally comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second tension adjusters. First and second bows are coupled to first and second tension adjusters. The system may comprise an eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

A liquid lens can include a chamber and a first fluid and a second fluid contained in the chamber. The first fluid and the second fluid may be immiscible, forming a fluid interface between the two fluids. The liquid lens may also include a first electrode insulated from the two fluids. The liquid lens may include a second electrode in electrical communication with the first fluid. The liquid lens may be configured such that a position of the fluid interface is based at least in part on voltages applied to the electrodes. The lens may further include a window configured to transmit light therethrough along an optical axis. Further, a flexible member may be configured to cause the window to displace axially along the optical axis to change the volume of the chamber.

An ostomy pouching system is described. A baseplate includes a seal adapted to be securely placed on the skin about the perimeter of tissue defining a stoma incised into a patient. An ostomy reservoir forms a sealed space within which discharge can be received and held. A flex layer includes a seal that is airtight, watertight, or both, and which is structurally interposed between at least a portion of two or more of the skin, tissue, stoma, baseplate, and ostomy reservoir. The flex layer includes a resiliently and elastically malleable phase change material. The flex layer is deformable such that at least one portion of the flex layer can transmute the magnitude of a force applied to the flex layer and redirect the force. External forces acting upon at least one of the skin, tissue, stoma, baseplate, and ostomy reservoir are mitigated, transmuted, and isolated by the flex layer.

A pair of eye goggles is provided. The pair of eye goggles includes a nosepiece fittable over a portion of a wearer's face, the nosepiece comprising one or more strands, at least a portion of the nosepiece comprising a phase change material, wherein a shape of the nosepiece changes upon an application of an energy to the phase changing portion to conform to the face; and a pair of eyepieces connected to the nosepiece.
