Carrera Goggles

Sunglasses were first used in Europe, Italy, and some portraits dating from the Middle Ages depict persons wearing eyeglasses. With the invention of printing in the 15th century, the demand for prescription and over in 1629 was enough to grant a charter to a guild of spectacle makers in England. The first bifocals were made for Benjamin Franklin at his suggestion about 1760. At first the glasses having spherical lenses were manufactured to correct nearsightedness and farsightedness. Only in the late 19th century did the cylindrical lens for correcting astigmatism come into common use.

Glasses lenses or prisms are brought before the eyes compensate for various defects of vision. The more common form of eyeglasses comprises a pair of plastic glasses in a metal or plastic frame mounted on the bridge of the nose. The frame is held in place by spring pressure on the nose or temples, or arms that encircle the head or hook around the ears. Eyeglasses with lenses made of hard plastic is commonly used for reasons of increased safety and light weight.

Other types of glasses include those who are held in place by pressure on the nose, usually called pince-nez (French, nose "pinch"). Single lenses used to correct vision in one eye, held in place by wedging into the orbit of the eye, are known as monocular. Glasses with a handle rather than temples, occasionally used for reading, are called opera glasses.

The lenses are ground in the form of spherical concave lenses for nearsightedness (myopia), convex spherical lenses for hyperopia (farsightedness), cylindrical lenses for astigmatism, and prisms for defects of convergence. Often, it is necessary to grind lenses in a combination of these forms to correct several deficiencies at once. Bifocal lenses are used to give a different amount of correction of distance vision and near work. The top of these lenses is a ground for far vision and the lower part for near vision, so that the user need only look down to read and bring them up to see distant objects. bifocals are trifocal which are on the ground with a lens center distance between.

The lenses are worn to protect eyes, and to correct visual defects. The colored glasses, or sunglasses, worn to protect eyes against the sun's rays are a familiar example. To protect their eyes from actinic rays of flame welding, workers wear glasses with a darker shade. Machinists and other plant workers wear goggles or glasses with a large force to protect their eyes from flying particles of metal, and aviators and racing drivers wear goggles to protect their eyes from the wind. Waterproof eye can see the divers underwater. Ski goggles to help skiers and sight.

Today, the glasses are not only correct your vision. They have also become fashion statements. For example, celebrities like Elton John and Lisa Loeb glasses are known for their ever-present. Ms. Jacky O. is also known for his signature big sunglasses the stars are still many imitating, like Nicole Ritchie and Paris Hilton.
