What is traditional eyewear? And what is modern eyewear? How to define them? And what are their advantages respectively?
The division of traditional eyewear and modern eyewear is the 20th century. Why? Since the first eye wear are invented, almost no substantial innovations and changes are made in the field- such situation does not change till almost the 20th century when revolutionary changes are taken places in glasses industry. By and large, eyeglasses before that time of period are designed in traditional styles with old materials- they can be called traditional eyeglasses; eye wear after that time are manufactured with more modern elements and can be called modern eyeglasses.
Apart from the different time, what else differences there are between traditional eyewear and modern eyewear? Generally speaking, modern eye wear are much advanced than those traditional ones, except in styles
Price should be a factor to be considered while comparing the two groups. Before the industrialization in glass field, eye wear are handmade only for those noble and rich people- eye wear in then time are luxury accessories. Later, as technology and techniques in the field matures on and on, the cost to make eye wear reduce all the more. For instance, some of nowadays modern eyewear can be purchased at several dollars.
Modern eyewear are much lighter and durable than those traditional eye wear. Eye wear in the past are inconvenient to use, for they are mainly made with glass and metal, which are heavy in weight. What’s worse, glass is such a fragile material that may break into pieces easily under impact; metal will also deform easily in the mean time. On the contrary, such defects can never be found on modern eye wear. They are made from light weight and durable materials. For example, the lenses can be made from plastic, like CR39, a kind of very lightweight material; if the prescription becomes stronger on and on, high index lenses are also available- thick and heavy glass lenses are no longer needed. The frames can also be made from memory materials, like titanium, memory plastic, which can rebound to their original shapes after being twisted and bended.
More fashionable elements can be found on modern eyewear than on traditional eye wear. When it comes to the 20th century, people begin to pay more attention to more than functionality that is what traditional glasses are mainly used for. And fashionable and personal elements are attached great importance since that period by both wearers and manufacturers. And now, many people tend to use eyeglasses as something of decoration, though many people are still in need of vision correction. One of such good example is the popularity of non prescription eyeglasses. These eye wear are specially designed for people who have no vision errors, but want to be as attractive and cool as those glasses wearers. To be simple, functionality is the main feature of traditional eye wear; fashionable and personal elements are now the main features on modern eye wear.
These are some advantages of modern eyewear over traditional eyewear. However, with the trend of returing to the old days, the styles of traditional eyewear are more popular than modern eyewear. So nowadays modern eyewear add more traditional elements, and this kind of eyewear is the latest modern eyewear.
