A swimming goggle structure comprises a frame. The frame includes a left frame, a right frame, and a bridge frame for connecting the left frame and the right frame. The lens of the swimming goggle structure is provided with a side-view lens portion for the wearer to observe the side view. Therefore, the visual field of the swimming goggles is more broadened, and the wearer can see a wider range when swimming, thereby improving the swimming experience. In addition, the wearer can know the dangerous situation in the water in time through the side-view lens portion, so as to avoid dangers in time and improve the safety of swimming.

A swimming cap made of a synthetic rubber and sized to substantially cover the scalp of a wearer's head, the cap having an opening formed in a posterior region thereof such that the wearer's hair can pass through the opening to form a ponytail.

A swim cap for persons having long hair includes a shell preferably having at least two interconnected compartments for receiving and encapsulating the hair of a user. The swim cap is secured around the head of a user by at least one draw string or adjustable band positioned within a channel near the open end of the swim cap as well as a chin strap extending downwardly from the cap. The interconnected compartments can be inflated to provide buoyancy. The shell further includes an outer layer and an inner layer defining a space therebetween that can also be inflated, or comprised of buoyant material, to provide buoyancy. A pump, compressed air canister or manual filler tube in communication with the interconnected compartments or space within the shell can be used to provide inflation. A pair of ear flaps extends downwardly from the swim cap around a user's head.

An adjustable eyewear restraint comprises a first strap having a first adjustment end and a first eyewear coupling end, and a second strap having a second adjustment end and a second eyewear coupling end. The straps are slidably and frictionally engageable to one another to allow adjustment of a length of the restraint by moving adjustment ends of the straps relative to each other. The straps can be slidably interwoven to each other about opening(s) of respective adjustment ends. The opening(s) slidably receive an opposing strap. A strap has a loop, coupleable to eyewear, that comprises first and second edges attached together to form an attachment portion substantially in-line with the first edge. A frictional element is frictionally and slidably coupleable to an earpiece to retain the loop and allow adjustment of a length of an eyewear retainer. Associated systems and methods are provided.

A swimming goggle and a strap structure are disclosed. The swimming goggle includes a goggle main body and the aforesaid strap structure. The goggle main body includes a lens assembly and two lateral connectors which are disposed on two sides of the lens assembly, respectively. The strap structure includes a strap body, an adjusting component and a positioning component. The strap body connects to the lateral connectors of the goggle main body. The adjusting component and positioning component are slidably disposed on the strap body and clamp the strap body. The adjusting component is in front of the positioning component. Therefore, the strap structure can be automatically adjusted to a suitable tightness.

The present pair of eye pieces may have a rotatable adjuster on the super structure of the eye pieces or on the headband between the eye pieces. When the rotatable adjuster is rotated one way, the headband decreases in effective length and tightens about the head of a user. When the rotatable adjuster is rotated the other way, the headband increases in effective length and loosens about the head of the user. With a rotatable adjuster, increases and decreases in length may be made in minute increments.

Disclosed are foldable swimming goggles. The swimming goggles include a left frame body and a right frame body, wherein the left frame body is provided with a supporting block and a limiting block, the supporting block is internally provided with an accommodating groove, a pressing shaft is clamped in the accommodating groove, the lower portion of the pressing shaft is fixedly provided with a positioning rotary wheel, and the right frame body is provided with a steering block. Firm connection of the product is completed through the pressing shaft and the positioning rotary wheel. When the swimming goggles need to be folded, the pressing shaft is pressed to separate the positioning rotary wheel from the steering block, so that the right frame body rotates to make the product folded.

Swimming goggles have a left-eye covering and a right-eye covering, each having a corresponding transparent window that defines a field of view and each further having a seal extending between the transparent window and the swimmer's face and formed to exclude water. A near-eye display is in signal communication with an image processor and forms a virtual image in the left- or right-eye field of view.
