What Could Bendable Sunglasses Do For You?

Bendable sunglasses, indicating from the name itself

, can be bended but will not be broken off. The reason why they could bear such an out-of-the-box functionality results from their raw materials for the eyeglass frames--the memory metal. In mention of bendable sunglasses, it is necessary to list relative information concerning memory metal at first.

It is Orlandi, a Swedish, who firstly discovered the magic function in Au-Cd alloy in 1932. He found it can magically reinstate to its original shape once after heated to certain jumping temperature even when it had been distorted severely. Since then this special Au-Cd alloy was named as memory metal, because it seems to be able to remember the original shape.

Although having only been developed for about 20 year, memory metal has been applied in various fields, ranging from the aviation domain to healing domain. The huge antenna on the artificial satellite are made from memory metal, which could be unfolded before launch and folded when the satellite is sent to the preset orbit, so as to receipt and send signals. In addition, widely applied in the clinical healthcare domain, memory metal plays an important role in the production of orthodontic retainer and thrombus filter, etc.. Besides, memory metal is closely related to items in our daily lives, for example, the work of detection and alarm equipment depends on the springs made from memory metal. When heated to certain temperature, the spring would reinstate, or say deform, which could make itself in touch with the switch. Then the bell rings.

Then, how will memory metal perform when it comes to the eyeglass manufacture domain? As well all know, eyeglasses are so easy to get broken off and most eyeglass wearers may have an experience of stepping on their glasses. I am one of them, and whenever it happens, I would sign that if there are bendable sunglasses, how wonderful it will be. Luckily enough, memory metal glasses make an achievement on it. According to the instruction, I find that I could simply restore their shapes by putting them in warm water or heating by harirdryers if I accidentally get them deformed. It is really a convenient way to save time and money, as well as energy.

Therefore, I strongly recommend people who are sloppy in daily lives to purchase bendable sunglasses, so that the possibilities for them to break up eyeglass legs would minimize, but to save money would maximize.
