.The reason why durable glasses are so durable mainly lies in the materials. Generally speaking, eye glasses are composed of two major parts, namely, the lenses and the frames. Therefore, durable glasses are also made from unique lenses and frames. From the perspective of history, the lenses of traditional eyeglasses are mainly made from glasses, which may break into pieces and will harmfully injure wearers' eyes. Later, some plastic lenses are invented; they also break easily, though they will not shatter. And the most widely used shatter-resistant lenses are made from a kind of polymer, called polycarbonate. Polycarbonate eyeglasses can withstand very strong impact and can well protect wearers' eyes. As for the frames, they are originally made from metal and other natural materials, which will deform easily after impact. And such situation is not changed though some new materials are invented until the employment of titanium and other memory metals. These special materials can rebound to their original shapes after being bended and twisted.

On the whole, durable eyeglasses are loved by almost all glasses wearers, particularly sportsmen and kids. The magic power of these eye wear can not be easily detected in daily lives, but in particular situations. For example, people who often play sports games and other related activities can benefit greatly from these durable eyeglass wears.

Kids may pay little to what will happen when they are playing. Therefore, what bothers parents most are eyeglasses in the past. And now, durable glasses with great power in resisting any impact and shatter have this problem easily resolved.
