Glasses, also known as eyeglasses or spectacles, are vision eyewear with clear or tinted lenses mounted in a frame that holds them in front of a person's eyes, typically utilizing a bridge over the nose and hinged arms, known as temples or temple pieces, that rest over the ears.
Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century, they were also known as sun cheaters.
Speedo International Limited is an Australian-British distributor of swimwear and swim-related accessories based in Nottingham, England.
A night-vision device (NVD), also known as a night optical/observation device (NOD) or night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 (image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards, and some can incorporate telescopic lenses. The image produced by an NVD is typically monochrome green, as green was considered to be the easiest color to look at for prolonged periods in the dark. Night vision devices may be passive, relying solely on ambient light, or may be active, using an IR (infrared) illuminator to visualize the environment better.
A diving mask is an item of diving equipment that allows underwater divers, including scuba divers, free-divers, and snorkelers, to see clearly underwater. Surface supplied divers usually use a full face mask or diving helmet, but in some systems the half mask may be used. When the human eye is in direct contact with water as opposed to air, its normal environment, light entering the eye is refracted by a different angle and the eye is unable to focus the light on the retina. By providing an air space in front of the eyes, the eye is able to focus nearly normally. The shape of the air space in the mask slightly affects the ability to focus. Corrective lenses can be fitted to the inside surface of the viewport or contact lenses may be worn inside the mask to allow normal vision for people with focusing defects.
Ray-Ban is a brand of luxury sunglasses and eyeglasses created in 1936 by Bausch & Lomb. The brand is best known for its Wayfarer and Aviator lines of sunglasses. In 1999, Bausch & Lomb sold the brand to Italian eyewear conglomerate Luxottica Group for a reported $640 million.
Goggles, or safety glasses, are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems.
Due to the nature of triathlons as a race consisting of multiple sports many pieces of technical equipment have been borrowed from other sports, or developed specifically in an effort to race faster and improve a competitors safety.
Competitive swimwear refers to the swimsuit, clothing, equipment, and accessories used in the aquatic sports of swimming, diving, synchronized swimming, triathlon, and water polo.
Mirrored sunglasses are sunglasses with a reflective optical coating on the outside of the lenses to make them appear like small mirrors. The lenses typically give the wearer's vision a brown or grey tint. The mirror coating decreases the amount of light passing through the tinted lens by a further 10–60%, making it especially useful for conditions of sand, water, snow, and higher altitudes. Mirrored sunglasses are one-way mirrors.

Aviator sunglasses are a style of sunglasses that was developed by a group of American firms. The original Bausch & Lomb design is now commercially marketed as Ray-Ban Aviators, although other manufacturers also produce aviator-style sunglasses.
Swedish goggles are a classic and popular type of swimming goggles worn by many competitive swimmers. The original Swedish goggles were produced by the Swedish company Malmsten AB and were first designed in the 1970s. Swedish goggles influenced many other goggle designs and generic Swedish goggles are widely available. Malmsten claims that Swedish goggles are "probably the worlds most copied swim goggles."
AN-6530 Goggles were produced during World War II as eye protection for United States Army and Navy flight crews. In 1943, the AN-6530 design replaced as standard the nearly identical USAAF B-7 goggle produced by Chas Fischer Spring Company of Brooklyn, New York. Contracts for AN-6530 goggles were awarded to Chas Fischer Spring Co. and American Optical.
A snorkel is a device used for breathing atmospheric air when the wearer's head is face downwards in the water with the mouth and the nose submerged. It may be either a separate unit, or integrated into a swimming or diving mask. The integrated version is only suitable for surface snorkeling, while the separate device may also be used for underwater activities such as spearfishing, freediving, finswimming, underwater hockey, underwater rugby and for surface breathing while wearing scuba equipment. A standard snorkel is a curved tube with a shape usually resembling the letter "L" or "J", fitted with a mouthpiece at the lower end and made from plastic, synthetic elastomers, rubber, or light metal. The snorkel may have a loop or a clip to attach it to the head strap of the diving mask or swimming goggles, or may be tucked between the mask-strap and the head. Some snorkels are fitted with a float valve at the top to prevent flooding if the top opening is immersed, and some are fitted with a water trap and purge valve, intended for draining water from the tube.
A swim brief or racing brief is any briefs-style male swimsuit such as those worn in competitive swimming, diving and water polo. The popularity of the Australian Speedo brand racing brief has led to the use of its name in many countries around the world to refer to any racing brief, regardless of the maker. Occasionally, the speedo genericized trademark is applied to square cut swimsuits, but in general the generic term is used in reference to swimming briefs. Swim briefs are also referred to as competition briefs, swimming trunks, bathers, togs, racer bathers, posing briefs, racing briefs, and colloquially in Australia, New Zealand, and the United Kingdom as budgie smugglers.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
Recon Instruments was a Canadian technology company that produced smartglasses and wearable displays marketed by the company as "heads-up displays" for sports. Recon's products delivered live activity metrics, GPS maps, and notifications directly to the user's eye. Recon's first heads-up display offering was released commercially in October 2010, roughly a year and a half before Google introduced Google Glass.
The history of competitive swimwear has been dominated by concerns over public nudity in the first half of the 20th century and by efforts to reduce water drag in the second half. Those efforts initially led swimmers to reduce the early sagging one-piece swimsuits down to briefs only. With the development of new materials that tightly fit the body and offered lower resistance to water than human skin, this trend was reversed to a complete body coverage from heels to neck and wrists. FINA banned full-body suits from competition effective from 1 January 2010, stating that it "wishes to recall the main and core principle is that swimming is a sport essentially based on the physical performance of the athlete".
Shred Optics is a manufacturer of sunglasses, helmets, and goggles designed for skiing, mountain biking, snowboarding, and other forms of outdoor recreation. The company is based in Park City, Utah, and Venice, Italy.
