A spectacle glasses is something that is exhibited to view. Typically, when using the word it is used to describe something extraordinary. One would think that by adding the letter "S" to the end of it, it would become plural.

Spectacle Glasses is actually a British term that is also used for eyeglasses. It sounds more sophisticated and if you dare to style, it can be highly fashionable and trendy.

When I think of spectacle glasses, I think of round glasses, like the ones worn by Abe Sapiens in the 2004 film of Hell boy. Round spectacle glasses are synonymous with many famous movie characters, rock stars, and celebrities.

Mahatma Gandhi, the spiritual leader for independence in India in the early 1900's, sported small round glasses that became iconic. In 2012, Gandhi’s round metal eyeglasses with their original case sold at auction for £34,000— double what was originally expected. They now reside in the Gandhi Museum in Madurai, India.

J.K. Rowling's character of Harry Potter was made famous for his scar on his forehead and his black round spectacle glasses. Every kid today likes to wear Harry Potter glasses every day and many dress up on Halloween. The entire costume is defined by the glasses.

We mostly remember certain people for their 'specs'. When thinking of music, I think of the Beatles. John Lennon, its lead singer/songwriter sported small round spectacle glasses that had a similar look to Gandhi.

I always get a kick out of it and laugh when I think of Professor Hubert from Futurama. He sported these round coke-bottle glasses while always saying "Good news, everyone!" talking about his latest inventions.

Some spectacle glasses are a spectacle glasses. Lady Gaga in her music video of Alejandro. She whores actual round lenses on her face. Elton John was most famous for wearing over sized round glasses that were flamboyant. My favorite pair of all time is Morpheus (Laurence Fishburne) in the matrix. His glasses just sat on his nose without arms.

When you think computers today, you think Apple. When you think Apple, you think Steve Jobs. Steve Jobs, had an iconic look wearing his turtleneck with rimless round glasses. Ozzy Ozbourne and Woody Allen are others who always sported round glasses.

Here at timetoshade.com, you too can get these looks. We carry most of these styles as well as many others. You can choose just the frames or turn your favorite frames into sunglasses too. Will you be the next person who will be known among your peers wearing round frames?

What do you know about Spectacle glasses?

Spectacle glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard

Plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

Spectacle glasses are typically used for vision correction, such as with reading spectacle glasses and Spectacle glasses used for nearsightedness.

Safety spectacle glasses provide eye protection against flying debris for construction workers or lab technicians; these spectacle glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety Spectacle glasses are used to protect against visible and near visible light or radiation. Spectacle glasses are worn for eye protection in some sports, such as squash.

Spectacle glasses wearers may use a strap to prevent the spectacle glasses from falling off during movement or sports.

Wearers of spectacle glasses that are used only part of the time may have the spectacle glasses attached to a cord that goes around their neck, to prevent the loss of the spectacle glasses and breaking.

Sun spectacle glasses allow for better vision in bright daylight and may protect one's eyes against damage from excessive levels of ultraviolet light.

Typical sun Spectacle Glasses lenses are tinted for protection against bright light or polarized to remove glare; Photochromatic spectacle glasses are clear in dark or indoor conditions, but turn into sun spectacle glasses when in they come in contact with ultraviolet light. Most over the counter sun spectacle glasses do not have corrective power in the lenses; however, special prescription sun spectacle glasses can be made.

Specialized spectacle glasses may be used for viewing specific visual information, for example, 3D spectacle glasses for 3D films (stereoscopy). Sometimes spectacle glasses are worn purely for fashion or aesthetic

purposes. Even with spectacle glasses used for vision correction, a wide range of fashions are available, using plastic, metal, wire, and other materials.

People are more likely to need spectacle glasses the older they get with 93% of people between the ages of 65 and 75 wearing corrective lenses.

Spectacle glasses can be marked or found by their primary function, but also appear in combinations such as prescription sun spectacle glasses or safety spectacle glasses with enhanced magnification.

Corrective

 Main articles: Corrective lens and Refractive error corrective lenses are used to correct refractive errors by bending the light entering the eye to alleviate the effects of conditions such as nearsightedness (myopia), farsightedness (hypermetropia) or astigmatism. The ability of one's eyes to accommodate their focus to near and distant focus alters over time. A common condition in people over forty years old is presbyopia, which is caused by the eye's crystalline lens losing elasticity, progressively reducing the ability of the lens to accommodate (i.e. to focus on objects close to the eye). Few people have a pair of eyes that show exactly equal refractive characteristics; one eye may need a "stronger" (i.e. more refracting) lens than the other.

Corrective lenses bring the image back into focus on the retina. They are made to conform to the prescription of an ophthalmologist or optometrist. A lens meter can be used to verify the

specifications of an existing pair of spectacle glasses. Corrective eye spectacle glasses can significantly improve the life quality of the wearer. Not only do they enhance the wearer's visual experience, but they can also reduce problems that result from eye strain, such as headaches or squinting.

The most common type of corrective lens is "single vision", which has a uniform refractive index. For

people with presbyopia and hyperopia, bifocal and trifocal spectacle glasses provide two or three different refractive indices, respectively, and progressive lenses have a continuous gradient.

Reading spectacle glasses provide a separate set of spectacle glasses for focusing on close-by objects. Reading spectacle glasses are available without prescription from drugstores, and offer a cheap, practical solution, though these have a pair of simple lenses of equal power, so they will not correct refraction problems

like astigmatism or refractive or prismatic variations between the left and right eye. For the total correction of the individual's sight, spectacle glasses complying with a recent ophthalmic prescription are required.

Adjustable-focus eye spectacle glasses might be used to replace bifocals or trifocals, or might be used to produce cheaper single-vision spectacle glasses (since they don't have to be custom-manufactured for every person).

Pinhole spectacle glasses are a type of corrective spectacle glasses that do not use a lens. Pinhole spectacle glasses do not refract the light or change focal length. Instead, they create a diffraction-limited system, which has an increased depth of field, similar to using a small aperture in photography.

This form of correction has many limitations that prevent it from gaining popularity in everyday use. Pinhole spectacle glasses can be made in a DIY fashion by making small holes in a piece of card which is then held in front of the eyes with a strap or cardboard arms.

Safety spectacle glasses with side shields

 Safety

Safety spectacle glasses are worn to protect the eyes in various situations. They are made with break-proof plastic lenses to protect the eye from flying debris or other matter.

Construction workers, factory workers, machinists, and lab technicians are often required to wear safety spectacle glasses to shield the eyes from flying debris or hazardous splatters such as blood or chemicals. As of 2017, dentists and surgeons in Canada and other countries are required to wear safety spectacle glasses to protect against infection from patients' blood or other body fluids.

There are also safety spectacle glasses for welding, which are styled like wraparound sun spectacle glasses, but with much darker lenses, for use in welding where a full-sized welding helmet is inconvenient or uncomfortable.

These are often called "flash goggles" because they protect welding flash. Nylon frames are usually used for protective eyewear for sports because of their lightweight and flexible properties. Unlike most regular spectacle glasses, safety spectacle glasses often include protection beside the eyes as well as in front of the eyes.

Sun spectacle glasses

 Main article: Sun spectacle glasses provide more comfort and protection against bright light and often against ultraviolet (UV) light. To properly protect the eyes from the dangers of UV light, sun spectacle glasses should have a UV-400 blocker to provide good coverage against the entire light spectrum that poses a danger.

Photo chromic lenses, which are photosensitive, darken when struck by UV light. The dark tint of the lenses in a pair of sun spectacle glasses blocks the transmission of light through the lens.

Light polarization is an added feature that can be applied to sunglass lenses. Polarization filters are positioned to remove horizontally polarized rays of light, which eliminates glare from horizontal surfaces (allowing wearers to see into water when reflected light would otherwise overwhelm the scene).

Polarized sun spectacle glasses may present some difficulties for pilots since reflections from water and other structures often used to gauge altitude may be removed. Liquid-crystal displays often emit polarized light making them sometimes difficult to view with polarized sun spectacle glasses. Sun spectacle glasses may be worn just for aesthetic purposes, or simply to hide the eyes.

Examples of sun spectacle glasses that were popular for these reasons include tea shades and mirror shades. Many blind people wear nearly opaque spectacle glasses to hide their eyes for cosmetic reasons.

Sun spectacle glasses may also have corrective lenses, which require a prescription. Clip-on sun spectacle glasses or sun glass clips can be attached to another pair of spectacle glasses. Some wrap-around sun spectacle glasses are large enough to be worn over top of another pair of spectacle glasses.

Otherwise, many people opt to wear contact lenses to correct their vision so that standard sun spectacle glasses can be used. Double frame eyewear with one set of lenses on the moving frame and another pair of lenses on a fixed frame (optional).

  Mixed double frame

The double frame uplifting spectacle glasses have one moving frame with one pair of lenses and the basic fixed frame with another pair of lenses (optional), that are connected by four-bar linkage.

For example, sun lenses could be easily lifted up and down while mixed with myopia lenses that always stay on. Presbyopia lenses could be also combined and easily removed from the field of view if needed without taking off spectacle glasses.

3D spectacle glasses

Main article: 3D Viewers

The illusion of three dimensions on a two-dimensional surface can be created by providing each eye with different visual information. 3D spectacle glasses create the illusion of three dimensions by filtering a signal containing information for both eyes.

The signal, often light reflected off a movie screen or emitted from an electronic display, is filtered so that each eye receives a slightly different image. The filters only work for the type of signal they were designed for.

Anaglyph 3D spectacle glasses have a different colored filter for each eye, typically red and blue or red and green. A polarized 3D system, on the other hand, uses polarized filters. Polarized 3D spectacle glasses allow for color 3D, while the red-blue lenses produce an image with distorted coloration.

An active shutter 3D system uses electronic shutters. Head-mounted displays can filter the signal electronically and then transmit light directly into the viewer's eyes.

Anaglyph and polarized spectacle glasses are distributed to audiences at 3D movies. Polarized and active shutter spectacle glasses are used with many home theaters. Head-mounted displays are used by a single person, but the input signal can be shared between multiple units.

Magnification (bi-optics)

Spectacle glasses can also provide magnification that is useful for people with vision impairments or specific occupational demands. An example would be bi-optics or bi-optic telescopes that have

Small telescopes mounted on, in, or behind their regular lenses. Newer designs use smaller lightweight telescopes, which can be embedded into the corrective glass and improve aesthetic appearance (mini telescopic spectacles). They may take the form of self-contained spectacle glasses that resemble goggles or binoculars or may be attached to existing spectacle glasses.

Yellow-tinted computer/gaming spectacle glasses

Yellow tinted spectacle glasses are a type of spectacle glasses with a minor yellow tint. They perform minor color correction, on top of reducing eyestrain due to lack of blinking. They may also be considered minor corrective unprescribed spectacle glasses.

Depending on the company, these computer or gaming spectacle glasses can also filter out high energy blue and ultra-violet light from LCD screens, fluorescent lighting, and other sources of light. This allows for reduced eye-strain.

These spectacle glasses can be ordered as standard or prescription lenses that fit into standard optical frames. Due to the ultra-violet light blocking the nature of these lenses, they also help users sleep at night along with reducing age-related macular degeneration.

Anti-glare protection spectacle glasses

Anti-glare protection spectacle glasses, or blue-light spectacle glasses, can reduce the reflection of light that enters our eyes. The lenses are given an anti-glare coating to prevent reflections of light under different lighting conditions.

By reducing the amount of glare on your eyes, vision can be improved. The anti-glare also applies to the outer glass, thus allowing for better eye contact. Frames The ophthalmic frame is the part of a pair of spectacle glasses which is designed to hold the lenses in proper position. Ophthalmic frames come in a variety of styles, sizes, materials, shapes, and colors.

·       Pair of end pieces connect the eye wires via the hinges to the temples

·       Pair of frame-front end pieces

· A pair of hinges connect the end pieces to the temples, allowing a swivel movement. Spring-loaded flex hinges are a variant that is equipped with a small spring that affords the temples a greater range of movement and does not limit them to the traditional, 90-degree angle.

Temple types

 ·       Skull temples: bend down behind the ears, follow the contour of the skull and rest evenly against the skull.

·       Library temples: generally straight and do not bend down behind the ears. Hold the spectacle glasses primarily through light pressure against the side of the skull.

·       Convertible temples: used either as library or skull temples depending on the bent.

·       Riding bow temples: curve around the ear and extend down to the level of the ear lobe. Used mostly on athletic, children's, and industrial safety frames;

·       Comfort cable temples: similar to the riding bow, but made from a springy cable of coiled metal, sometimes inside a plastic or silicone sleeve. The tightness of the curl can be adjusted along its whole length, allowing the frame to fit the wearer's ear curve perfectly. Used for physically.
