Standing less than a foot tall, with a whiskered, feline muzzle, welding goggles, and giant hands, the alien creature looked like a kitten engineer.

The $3603 V2360 headset, which Dlodlo (pronounced "dwo-dwo") announced on Monday, looks like a cross between welding goggles and, as my colleague Thomas Ricker put it, something a Las Vegas Elvis impersonator might wear.

When Epic made the first-person shooter tech demo Bullet Train, its developers donned headsets like welding goggles, pulling them up to edit the world on a flat screen and putting them on again to test it.

This is a problem endemic to the industry, but it's worth reminding ourselves that the average consumer isn't interested in sweating up their heads with massive, weighty all-black welding goggles — especially not when the resolution is still not at the retinal level where we might find it indistinguishable from real life.

The band appeared on Top of the Pops with Ginger wearing green welding goggles. The debut album was reissued in late 1994 with "Caffeine Bomb" tacked on as an extra track.

Simple gas welding goggles Welding goggles provide a degree of eye protection while some forms of welding and cutting are being done. They are intended to protect the eyes not only from the heat and optical radiation produced by the welding, such as the intense ultraviolet light produced by an electric arc, but also from sparks or debris. A full facemask may be required for arc welding. Welding and cutting processes, including arc welding and cutting, as well as brazing produce intense ultraviolet (UV), infrared (IR) and visible light wavelengths.

Rabi arrived late and found the only entry left was for 18 kilotons, which he purchased. Wearing welding goggles, he waited for the result with Ramsey and Enrico Fermi. The blast was rated at 18.6 kilotons, and Rabi won the pool.

Welding glass protects against glare and flying sparks. It is a more extreme implementation of the same idea as sunglasses, suited to the more intense light generated during welding. Arc welding goggles must be much darker than blowtorch goggles. Shades 12, 13, and 14 welding glass must be used to stare directly at the sun or a solar eclipse.

Praseodymium(III) oxide can be used as a dielectric in combination with silicon. Praseodymium-doped glass, called didymium glass, turns yellow and is used in welding goggles because it blocks infrared radiation. Praseodymium(III) oxide is also used to color glass and ceramics yellow. For coloring ceramics, also the very dark brown mixed-valence compound praseodymium(III,IV) oxide, Pr6O11, is used.

To help make the decision, he flew helicopters and airplanes wearing special welding goggles to simulate different lighting conditions. See also landed helicopters with Jim Lovell on lava flows that simulated the terrain on the Moon. See was announced as the backup pilot for Gemini 5 on February 8, 1965, with Armstrong serving as the backup command pilot. They were the first civilians selected for a spaceflight.

The observers set up a betting pool on the results of the test. Edward Teller was the most optimistic, predicting . He wore gloves to protect his hands, and sunglasses underneath the welding goggles that the government had supplied everyone with. Teller was also one of the few scientists to actually watch the test (with eye protection), instead of following orders to lie on the ground with his back turned.

Any intense exposure to UV light can lead to photokeratitis. Common causes include welders who have failed to use adequate eye protection such as an appropriate welding helmet or welding goggles. This is termed arc eye, while photokeratitis caused by exposure to sunlight reflected from ice and snow, particularly at elevation, is commonly called snow blindness. It can also occur due to using tanning beds without proper eyewear.

Neodymium(III) oxide is used to dope glass, including sunglasses, to make solid-state lasers, and to color glasses and enamels. Neodymium-doped glass turns purple due to the absorbance of yellow and green light, and is used in welding goggles. Some neodymium-doped glass is dichroic; that is, it changes color depending on the lighting. One kind of glass named for the mineral alexandrite appears blue in sunlight and red in artificial light.

Proper protection such as welding goggles should be worn at all times, including to protect the eyes against glare and flying sparks. Special safety eyewear must be used—both to protect the welder and to provide a clear view through the yellow-orange flare given off by the incandescing flux. In the 1940s cobalt melters’ glasses were borrowed from steel foundries and were still available until the 1980s. However, the lack of protection from impact, ultra-violet, infrared and blue light caused severe eyestrain and eye damage.

According to Riddick, while in Butcher Bay he received eye surgery (a "surgical shine job", as he calls it) from a doctor who gave him permanent night vision in exchange for "20 menthol KOOLs". The surgery made his eyes more sensitive to normal light, requiring him to wear welding goggles to protect them (although he has also been shown without the goggles in a regularly illuminated room). In the flash movie on the Pitchblack.com website, Riddick gets the eye-shine to give him more of an advantage following an encounter with humanoids called "shiners".

The UV and IR wavelengths cannot be seen and can produce eye injury without the victim realizing it immediately. Extremely dark filters of the proper sort are needed for the welder to be able to look at the intensely glowing metal being welded. An approved face shield or welding helmet can also have filters for optical radiation protection, and offer additional protection against debris and sparks. UV blocking protective spectacles with side shields or welding goggles are considered primary protection, with the face shield or welding helmet considered secondary protection.

The injury may be prevented by wearing eye protection that blocks most of the ultraviolet radiation, such as welding goggles with the proper filters, a welder's helmet, sunglasses rated for sufficient UV protection, or appropriate snow goggles. The condition is usually managed by removal from the source of ultraviolet radiation, covering the corneas, and administration of pain relief. Photokeratitis is known by a number of different terms including: snow blindness, arc eye, welder's flash, bake eyes, corneal flash burns, sand man's eye, flash burns, niphablepsia, potato eye, or keratoconjunctivitis photoelectrica.

Riddick is Furyan, a member of a warrior race of adapted humans obliterated by a military campaign that left Furya desolate, and is one of the last of his kind. One of his most defining features are his eyes, a characteristic inherent in a certain caste of his species (the Alpha- Furyans), although he implies in Pitch Black that they were "shined" by a back-alley surgical operation. This allows him to see clearly in the dark, but also makes him vulnerable to strong light; he wears tinted welding goggles for protection. Riddick was once a mercenary, then part of a security force,The Chronicles of Riddick, Special Features and later a soldier.

The optical filter in welding goggles, face mask or helmet must be a type which is suitable for the sort of work being done. A filter suitable for gas welding, for instance, should not be used for arc welding. Face masks which are self dimming are available for arc welding, MIG, TIG, and plasma cutting, and allow better vision before the arc is struck and after it is extinguished. Failure to use such protection when arc welding or even being near where arc welding is going on can result in a painful condition called "arc eye", or photokeratitis, which is akin to a severe sunburn of the cornea and conjunctiva of the eye.
