Evolution of eye glasses
We generally take for granted one of the world’s most important inventions – spectacles. Imagine what life would be like not being able to see images clearly or sharply. 1According to a January 11, 1999 feature article in Newsweek Magazine, reading glasses are one of the most important inventions of the past 2000 years. They developed because of the work of artisans, like glassmakers, jewelers and clockmakers, along with some of the most brilliant scientific minds over the centuries. No one really knows about the early history of image magnification. In ancient times, someone noticed that convex-shaped glass magnified things. 2Sometime between the year 1000 and 1250 crude mechanical grinding technology began to develop regarding rock crystal reading stones.
Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash.
3Sign of Social Acceptability – Intelligence and Wealth
Eyeglasses went through stages in social acceptability, as well. At some points, they were regarded as status symbols or as symbols of intelligence and wealth, while at other times they were considered embarrassments because they exposed physical weakness.

4Eyeglass Frame Materials
Eyeglass frame materials, too, have been revolutionize with the advent of new plastics and various types of metals. Frames generally are fabricated from plastic or metal, but a wide variety of materials can be used, depending on the desired characteristics of the frame.

For example, for safety glasses, you may require a durable, lightweight frame material, such as polycarbonate. If you suffer from skin allergies, you probably should look for eyeglass frames made of hypoallergenic materials, such as titanium or stainless steel, to avoid a skin condition known as contact dermatitis.

Some eyeglass frames have components that can be snapped into place, rather than attached by screws or other means. This type of feature can be handy if you choose to "mix and match" different colored temples with the same set of lenses.

Certain types of eyeglass frames now also are highly flexible, which reduces the possibility of breakage. Spring hinges are also flexible. These types of frames are ideal for kids eyeglasses, because of the durability factor. Improved designs of nose pads also contribute to comfort and the look of how eyeglasses are positioned in front of the face. New silicone nose pads, for example, can prevent "slippage" but are so lightweight and soft that they are hardly noticeable.

The invention of eye glasses interlaces with other pieces of history. Tradition and fashion also played a role in the evolution of this instrument. Here is an eyeglasses timeline to see how eyeglasses have evolved.
20th Century
5At the beginning of the 20th century, eyeglass manufacturers began to emphasize style as well as function. Eyeglasses are a fashion statement as much as a practical necessity and countless designers have turned their talents to creating the styles of the moment. Frame styles branded with high profile designer names like Calvin Klein, Jones New York, and Marc Jacobs continue to be in demand. Eyeglasses came to be considered a component of fashion; as such, various different styles have come in and out of popularity. Most are still in regular use, albeit with varying degrees of frequency. You can find thousands of styles of eyeglasses in all shapes, sizes, and colors. You can even order eyeglasses online by visiting a retailer.

The 1900s
6During the 1900s, the manufacture of eyeglasses became a booming industry in itself. The range of styles available became extensive as Hollywood expanded and celebrities began to influence the fashions of the time Improved plastics used to make frames in the early 1900s presented new frame styling.
This style was popular during 1900-1920. It was a French style featuring a small frame that fit snugly over the face and pinched the nose.
Round Lenses

The Hollywood actor named Harold Lloyd influenced the round lences, the Pince-Nez was mercilessly thrown out of style in the late 1920s. The style was replaced by a large round lens inside a tortoiseshell frame.

The Upsweep
In the 1940s, the frame of the moment featured an upsweep on the top rim, simulating the sweep of a woman’s eyelashes. The frames themselves became available in a variety of colours . By the 1950s, eyeglasses had become a popular fashion accessory in Europe and the United States. Wearers demanded comfortable and stylish designs which displayed elegance while remaining functional. Today, eyeglasses are an accessory that not only improve vision, but also display personality.
The 1800s
7During the 1800s, the manufacturing of eyeglasses took on a much larger scale and people were able to purchase them for reasonable prices from many shops and merchants.
Common Styles
In the 1800s, there was societal view that wearing glasses was a sign of ill health and old age. For this reason people wanted to avoid wearing glasses. The Lorgnette was a clever compromise. The design featured a pair of glasses but with a long handle instead of temples.
The 1700s
8The next point of extensive development for eyeglasses occurs in the 1700s. In this century, eyeglasses were developed to include the temples that secure the frames over the ears. They were also made by hand.
Common Styles
Wig Spectacles
These particular style of glasses were characterized by the long temple pieces that extended over the ears. They were called wig spectacles because of their popularity among men who wore wigs.
Still a common type today. The bifocal was invented in 1784 by Benjamin Franklin. They include a lens that can accommodate both short and long vision.
The 13th century
9Mankind struggled without any visual aids until the end of the 13th century. It was during this period when the earliest form of the eyeglasses was invented in northern Italy. These glasses were more akin to magnifying glasses as opposed to the spectacles that we're familiar with today. It wasn’t uncommon for merchants to carry spectacles as they journeyed along the Silk Road to Asia. These spectacles were symbols of status. Some Chinese judiciary committees dictated that spectacles were now a part of the court uniform. Though they were quite popular in Asia, spectacles were far more popular in Europe
