Generally, blue sunglasses are mainly composed of two parts- lenses and frames, or in some other cases, nose pads are also included. Lenses and frames are usually made from different materials.
Glass- the earliest material used to make sunglasses lenses. Glass is very traditional materials, but is still very popular among some wearers. It has many merits, like great optical acuity, relatively cheap, etc. On the contrary, it is fragile and broken easily, heavy to wear, etc. But some new glass in the industry has maintained its merits and overcome the aforesaid defects.
Polycarbonate is now one of the most popular materials employed to make blue sunglass lenses. Traditional lenses are very fragile or can not stand very strong explosive. And polycarbonate lenses are totally different- they can combat very fierce shatters and are first choices for many sportsmen.
Metal is the most traditional materials used to make blue sunglass frames. According to some data, the earliest real sunglasses are made from metal frames. Metal frames are very hard and can help firmly fix the sunglasses onto the wearers’ heads. But metal will be out of shape if not handled properly. Or even some people are sensitive to metal frames- but some special coating on them can help solve this problem. Now, some memory metal is very popular and can help avoid its original demerits.
Titanium is one of the latest materials used to make blue sun glasses frames. It has the merits of both plastic and metal- lightweight and strong. And now there are still memory titanium- a much advanced material than common titanium.
Plastic is one of the most popular materials both for blue sunglass lenses and frames. Plastic sunglasses did not come into being until the early years of last century. It is a new time when plastic was widely used in glasses field. Some lenses and frames are mainly made from plastic. The plastic lenses are lightweight, shatter-resistant and can bring wearers great comfort. But they are scratched easily and require highly on temporary, humidity and other factors.
