Eyeglass Info: About Eyeglasses

What About Eyeglasses?

Eyeglasses are devices for aiding, improving or correcting defective sight. In addition correcting various eye conditions, eyeglasses are also utilized for protecting eyes from damage caused by sunlight, ultraviolet light or flying objects. Eyeglasses typically consist of a pair of glass or plastic lenses mounted in a frame that sits on the bridge of the nose and is held in place with arms that rest or are hooked behind the ears.

Eyeglasses are Made from High-Tech Materials:

Eyeglass lenses, originally made exclusively from glass, have evolved to include high-tech polymer materials such as CR39, Transitions® (photochromic plastic), Polycarbonate, and High Index plastic. Lastly, multifocal lenses have been developed which contain two or more vision-correcting prescriptions in one lens (ex. Bifocals = lenses split into two sections; the upper part is for distance vision and the lower part is for near vision, and Progressives = lenses that gradually change prescription from normal distance vision at the top to intermediate vision (arms length vision) in the middle to a reading prescription at the bottom. Further, eyeglass materials have options for individual needs consisting of lens filters that block the ultraviolet (UV) light, anti-scratch coatings that increase the surface hardness of lenses (an important feature when using plastic lenses) and anti-reflective (AR) coatings that eliminate significant glare and allow other people to see the eyes of the wearer. There is also a full spectum of eyeglass lens tints, from lighter tints to darker tints, for use in sunglasses.

Eyeglasses Correct Four Main Vision Problems:

There are four vision deficiencies for which eyeglasses can compensate. Nearsightedness (myopia) is a vision disorder that causes far objects to appear blurred but near objects are seen clearly. Corrective eyeglasses with concave (inwardly curved) lenses compensate for the refraction error by moving the image of a distant object backward onto the retina Farsightedness (hyperopia) is a condition that allows far objects to be seen clearly but presents difficulty with near vision. Corrective eyeglasses with convex (outwardly curved) lenses compensate for the refraction errors by moving the image of a distant object forward onto the retina. Astigmatism is a vision disorder caused by a non-uniform curvature in the refractive surfaces of the eye. Light rays do not all come to a single focal point on the retina, some focus on the retina while others focus in front or behind it. This condition can occur in conjunction with nearsightedness or farsightedness. A special cylindrical lens is placed in the eyeglasses to correct the condition. Presbyopia is a condition that exists when the natural crystalline lens of the eye loses some of its ability to change shape in order to focus on near objects. Typically, people moving beyond the age of 40 eventually develop presbyopia, which is indicated by a need for reading or bifocal eyeglasses. Corrective eyeglasses with convex lenses compensate for these refractive errors.

Eyeglasses as Fashion:

Nowadays, eyeglasses have developed into fashion accessories that can completely transform your image. No more are the days when eyeglasses were worn solely to correct one's vision. While focusing on the aspects of Fashion, Fit and Function, consumers can assertively shop for eyeglasses that will surely fulfill all of their needs. It's as easy as deciding the look you want, defining the shape of your face and your coloring and choosing the eyeglass materials and frame that best complements your hair, eyes and skin tones.
