Eyewear
Eyewear is a term used to refer to all devices worn over both of a person's eyes, or occasionally a single eye, for one or more of a variety of purposes. Though historically used for vision improvement and correction, eyewear has also evolved into eye protection, for fashion and aesthetic purposes, and starting in the late 20th century, computers and virtual reality. The primary intention of wearing eyewear can vary based on the need or desire of the wearer. Eyewear comes in different forms such as Glasses, Contact lenses, Sunglasses and many more. . Eyewear (such as glasses and contact lenses) helps most people see clearer or read. Eyewear also can be used for protection, such as sunglasses which protect wearers from the Sun's ultraviolet rays which are damaging to the eyes when unprotected, eyepatches to protect injured eyes from further damage, or goggles which protect the wearer's eyes from debris, water and other chemicals. Variants of eyewear can conversely inhibit or disable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luxottica
Luxottica Group S.p.A. is an Italian glasses, eyewear multinational corporation headquartered in Milan. As a vertically integrated company, Luxottica designs, manufactures, distributes, and retails its eyewear brands through its own subsidiaries. It is the largest eyewear company in the world.

Ray-Ban
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. History In 1929, US Army Air Corps Colonel John A. Macready worked with Bausch & Lomb, a Rochester, New York–based medical equipment manufacturer, to create aviation sunglasses that would reduce the distraction for pilots caused by the intense blue and white hues of the sky. Specifically, Macready was concerned that pilots' goggles would fog up, greatly reducing visibility at high altitude. The prototype, created in 1936 and known as "Anti-Glare", had plastic frames and green lenses that could cut out the glare without obscuring vision. The name "Ray-Ban" was hence derived from the ability of these glasses to limit the ingress of either ultra-violet or infra-red rays of light. Impact-resistant lens ...

Persol
Persol is an Italian luxury eyewear brand specializing in the manufacturing of sunglasses and optical frames. It is one of the oldest eyewear companies in the world and is owned by the Luxottica group. The name is derived from the Italian ''per il sole'', meaning "for the sun". Formed in 1917 by Giuseppe Ratti, Persol originally catered to pilots and sports drivers. Currently, the company markets durable sports sunglasses. The company trademark is a silver arrow. History In 1917 Giuseppe Ratti, owner of Berry optical, started producing his first glasses and lenses for athletes and aviators. The company developed a flexible stem, known as the patented Meflecto system, which was one of the first spring hinges for eyewear. Persol was introduced to the United States in 1962 and opened its first boutique on Rodeo Drive in Beverly Hills in 1991. Technology Currently all plastic Persol spectacles are made in Italy using cellulose acetate In biochemistry, cellulose acetate refer ...

Eyepatch
An eyepatch is a small patch that is worn in front of one eye. It may be a cloth patch attached around the head by an elastic band or by a string, an adhesive bandage, or a plastic device which is clipped to a pair of glasses. It is often worn by people to cover a lost, infected, or injured eye, but it also has a therapeutic use in children for the treatment of amblyopia. Eyepatches used to block light while sleeping are referred to as a sleep mask. An eyepad or eye pad is a soft medical dressing that can be applied over an eye to protect it. It is not necessarily the same as an eyepatch. History In the years before advanced medicine and surgery, eyepatches were common for people who had a lost or injured eye. They were particularly prevalent among members of dangerous occupations, such as soldiers and sailors who could lose an eye in battle. While stereotypically associated with pirates, there is no evidence to suggest the historical accuracy of eye patch wearing pirates bef ...

Google Glass
Google Glass, or simply Glass, is a discontinued brand of smart glasses developed by Google's X Development (formerly Google X), with a mission of producing a ubiquitous computer. Google Glass displays information to the wearer using a head-up display. Wearers communicate with the Internet via natural language voice commands. Google started selling a prototype of Google Glass to qualified "Glass Explorers" in the US on June 27, 2012, for a limited period for $1,500, (with distribution of those purchases beginning on April 16, 2013), before it became available to the public on April 15, 2014. It has an integrated 5 megapixel still/720p video camera. The headset received a great deal of criticism amid concerns that its use could violate existing privacy laws. On January 15, 2015, Google announced that it would stop producing the Google Glass prototype. The prototype was succeeded by two Enterprise Editions, whose sales were suspended on March 15, 2023. More than a decade later, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blindfold
A blindfold (from Middle English ') is a garment, usually of cloth, tied to one's head to cover the eyes to disable the wearer's sight. While a properly fitted blindfold prevents sight even if the eyes are open, a poorly tied or trick blindfold may let the wearer see around or even through the blindfold. Applications Blindfolds can be used in various applications: * As a sleep mask: They block out light when sleeping, especially during air travel, or for those who sleep during the day, given that shutting out light allows the user to achieve a deeper level of sleep. They can also provide relief from claustrophobia for magnetic resonance imaging (MRI) patients. * In children's games, such as Pin the Tail on the Donkey and when hitting a piñata. * During both martial arts and weight lifting, to encourage reliance on other senses, such as touch or hearing. * As an added challenge in activities such as chess and speedcubing, forcing participants to rely purely on their memo ...

Sunglasses
Sunglasses or sun glasses (informally called shades or sunnies; more names Sunglasses#Other names, below) are a form of Eye protection, 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, polarizer, polarized or darkened. In the early 20th century, they were also known as sun cheaters (cheaters then being an United States, American slang term for glasses). Since the 1930s, sunglasses have been a popular fashion accessory, especially on the beach. The American Optometric Association recommends wearing sunglasses that block ultraviolet radiation (UV) whenever a person is in the sunlight to protect the eyes from UV and blue light, which can cause several #Protection, serious eye problems. Their usage is mandatory immediately after some surgical procedures, such as L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blinders (poultry)
Blinders, also known as peepers, are devices fitted to, or through, the beaks of poultry to block their forward vision and assist in the control of feather pecking, cannibalism and sometimes egg-eating. A patent for the devices was filed as early as 1935. They are used primarily for game birds, pheasant and quail, but also for domestic turkey, turkeys and Chicken, laying hens. Blinders are opaque and prevent forward vision, unlike similar devices called chicken eyeglasses, spectacles which have transparent lenses. Blinders work by reducing the accuracy of pecking at the feathers or body of another bird, rather than spectacles which have coloured lenses and allow the bird to see forwards but alter the perceived colour, particularly of blood. Blinders are held in position with a circlip arrangement or lugs into the nares of the bird, or a pin which pierces through the nasal septum. They can be made of metal (aluminium), neoprene or plastic, and are often brightly coloured making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Shutter 3D System
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique for displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image. Modern active shutter 3D systems generally use liquid crystal shutter glasses (also called "LC shutter glasses" or "active shutter glasses"). Each eye's glass contains a liquid crystal layer which has the property of becoming opaque when voltage is applied, being otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately block one eye, and then the other, in synchronization with the refresh rate of the screen. The timing synchronization to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night-vision Device
A night-vision device (NVD), also known as a night optical/observation device (NOD) or night-vision goggle (NVG), is an Optoelectronics, optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances Available light, ambient visible light and converts Infrared#Regions within the infrared, near-infrared light into visible light which can then be seen by humans; this is known as I2 (Image intensifier, image intensification). By comparison, viewing of infrared thermal radiation is referred to as Thermography, 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 an optional mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front/Objective (optics), objective lens to prevent damage by environmental hazards, while some incorporat ...

Virtual Reality Headset
A virtual reality headset (or VR headset) is a Head-mounted display, head-mounted device that uses 3D near-eye displays and positional tracking to provide a virtual reality environment for the user. VR headsets are widely used with Virtual reality game, VR video games, but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), Stereophonic sound, stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose tracking, pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world. Augmented reality (AR) headsets are VR headsets that enable the user to see and interact with the outside world. Examples of AR headsets include the Apple Vision Pro and Meta Quest 3. VR headsets typically use at least one MEMS IMU for three degrees of freedom (3DOF) motion tracking, and optionally more tracking t ...

Glasses Black
Glasses, also known as eyeglasses (American English), spectacles ( Commonwealth English), or colloquially as specs, 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 for support. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness; however, without the specialized lenses, they are sometimes used for cosmetic purposes. Safety glasses are eye protection, a form of personal protective equipment ( PPE) that are worn by workers around their eyes for protection. Safety glasses act as a shield to protect the eyes from any type of foreign debris that may cause irritation or injury; these glasses may have protection on the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
