Sunglasses are an important accessory during an outdoor activity, sport or just a regular entertainment. Regardless of the detailed usage circumstances, one point is undeniable that sunwear products usually function in outdoor environments. Another associated point is that active individuals like professional athletes and sports amateurs are more likely to use a pair of sunshades. Of course, people wandering around the streets may also take sunglasses as an accessory. But for people who spend much time in doing outdoor activities or sports, sunglasses mean a lot in terms of eye protection provisioning. Yet it is also important to make sure the sunwear can last long even under regular usage. This reasonable requirement makes bendable sunglasses a natural choice. Today, bendable sunwear is very popularly because of its unusual flexibility.
Sometimes called memory metal sunglasses, these products can be twisted, bended like a pretzel but they will go back to the original shape. Contributed by this advanced feature, these glasses are less likely to break or bend up, leading hardly to any adjustments. Of course, bendable sunglasses take a little longer time to make the original adjustment during production. After forming the original shape, bendable sunglasses can maintain the shape for a much longer time than frames made of other materials. This flexibility makes memory metal sunglasses quite durable and more resistant to accidental bending or twisting. However, it is unadvisable to just twist bendable frames only for fun, because they can be definitely broken. Moreover, some models use plastic temples or semi-rimless styles.
The above precious capability makes these bendable sunglasses particularly suitable for active children and sports enthusiasts. Where does this capability come from? In fact, the frames are made of a shape memory alloy, which can remember its original, cold-forged shape. This material is now widely used by several eyewear manufacturers like Marchon and Nike in their products. Furthermore, this alloy contains a famous ingredient called titanium, bringing additional features like lightweight, hypoallergenic and corrosion-resistant.
