Maybe most of us have the same experience that when choosing glasses, we would easily get confused since there are so many different types of frames and lenses. What’s more, we are not even sure about the relationship between glasses and their prices. For example, why some lenses are more expensive than others and why those frames made of the same kind of material have relatively different prices? In order to answer these confusing questions, we have to be clear about how these differences of the prices come from, even when the materials are the same.
We could take the popular plastic frames nowadays as an example. Though the material of the frames— plastic seems to be the same, actually there are a lot of things that contribute all the high and low prices. A pair of frames much more expensive than those others must have some special characters. Usually, the more expensive ones could easily be bent down and twisted while at the same time, they are able to recover to their previous condition as soon as the outer pressure disappears. See? That is one of the reasons of why those kinds of frames are much more expensive. The unique characters determine the value of the frames.
As for the lenses, I think most of us may have got some knowledge about the different prices of the lenses. Generally speaking, the materials of the lenses affect a lot of the prices. That is because some kind of lenses can prevent ultraviolet radiation from entering through the lenses so as to protect out eyes. Another kind of material could be made into much thinner lenses than others. In this way, some high myopia people could releases some pressure on their noses from the heavy thick lenses.
Simply because of some reasons like those mentioned above, those frames and lenses could be variable in their prices. After all, when choosing a pair of glasses, we should first bear some basic knowledge about the frames and lenses as well as out own needs. Then with the help of the assistants in the shops, we could enjoy our shopping and finally have a beloved pair of glasses.
