Materials of Frames and Lenses Used in Blue Eyewear

Blue eyewear are very popular among people of different age all over the world, especially blue sunglasses. They are eyewear tinted blue, some in frames, some in lenses. However, the frames and lenses are somewhat the same as other eyewear.

Titanium is one of the latest materials used to make blue eyewear 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 eyewear 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. Plastic frames are also lightweight and but will break easily. Later, the development technology has promoted the coming of memory plastic for frames. Those latest materials can rebound their previous forms after bending.

Metal is the most traditional materials used to make blue eyewear 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.

Glass- the earliest material used to make eyewear 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 eyewear. 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.

If you like blue or you match blue well, you can have a try of blue eyewear. Maybe they will create a unpredictable good effect on you. Blue eyewear is only one of some popular tinted eyewear. If you don’t like blue, you can also try other colors.
