A swim goggles (1) with a spacing adjuster, comprising a left and right eyepiece (2) retained in a frame (4), and an adjustment means (6) for adjusting the spacing (7) between the left and right eyepieces (2) composed of a rotating element (16), which is located between two connecting pieces (5), such that it can be adjusted, and is connected at each end with two opposing threaded connections (18, 19; 20, 21) to the connecting pieces (5), wherein the connecting pieces (5) have a twisting safeguard (8, 8a, 34) that prevents a twisting of the connecting pieces (5) counter to one another in the frame (4).

A sport goggle strap for affixing sport goggles to the face of a user with first and second end portions, each having a connection member for attaching the first and second end portions to opposite sides of sports goggles, and an intermediate portion between the first and second end portions having an elongated opening disposed substantially in line between the first and second end portions. The first end portion, second end portions and the intermediate portion are comprised of a unitary piece of an elastomeric material, and preferably neoprene.

An eye protection system including a reservoir for containing a product, the reservoir securable to a strap of an eye protection system. A spout communicatively coupled to the reservoir, the spout for dispensing the product to a lens of the eye protection system while the reservoir is secured to the strap.

A waterproofed wearable displaying device with an augmented reality function. The wearable displaying device is in form of goggles. A waterproofer is attached in front of a lens of the goggle. A receiving space defined between the waterproofer and the lens is sealed. The wearable displaying device further includes an image capturing device and a display in the receiving space. When the user wears the wearable displaying device indoors or outdoors, the display faces to the user's eyes, and modules in the device can detect air pressure and humidity in the goggles, to maintain air pressure within the goggles at a slight vacuum compared to the air pressure outside.

A strength training apparatus includes a rack configured to hold a bar between exercises performed using the bar, at least one light source coupled to the rack, and a controller communicable with the light sources. The controller is programmed to determine a desired range of motion for a current exercise and control the at least one light source to display an illumination pattern based on the desired range of motion.

A system for the color coding of objects in the field of view of a plurality of spectacle wearers includes a pair of spectacles per spectacle wearer. Liquid crystal cells of at least one spectacle lens of the spectacles are so designed that a transmission (TR) of the liquid crystal cells may be switched between high and low transmission states. The system also includes one RGB light source per spectacle wearer and means for controlling or regulating the luminance times, color and intensity of the RGB light source such that the light source for a first spectacle wearer illuminates with a first color at a time of the state of high transmission of the liquid crystal cell and the light source for a second spectacle wearer illuminates at a time of high transmission of the liquid crystal cell of their spectacles with a second color different from the first.

The invention relates to a system for visual enhancement. The system suppresses glare and includes a spectacle lens having a liquid crystal cell, the transmission of which can be switched between high and low transmission states. The system also includes at least one sensor for measuring the brightness of the visible light incident on it, the sensor being arranged on the eye side of the spectacle lens and measuring the brightness entering through the at least one spectacle lens. The system also includes a closed loop control circuit for regulating the transmission of the liquid crystal cell so that the times of the state of high transmission become shorter with increasing glare. The system includes a display for controlling the lighting times and the luminous intensity of the display during the state of high transmission of the liquid crystal cell.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

Disclosed herein is a snorkeling mask. The snorkeling mask includes: goggles configured to enable a wearer to see underwater while surrounding the facial region of the wearer; a snorkel configured such that one end thereof is connected to the mouth of the wearer and the other end thereof is exposed out of a water surface; and a connection tube configured to connect the goggles and the snorkel to each other so that the insides of the goggles and the snorkel communicate with each other, and configured such that a portion thereof is inserted into the snorkel to a predetermined length. When an inspiratory breath of the wearer passes over the inserted portion of the connection tube while passing through the inside of the snorkel and being discharged to an outside, moisture inside the goggles passes through the connection tube and is discharged to the outside according to Bernoulli's principle.
