As the name implies, unbreakable glasses are break-resistant, durable and can be twisted. Besides, those eyeglasses can also be made according to your vision requirement. From the vision perspective, the most important part of a pair of eyeglasses is definitely the lenses, but the frames are important, too. So, when it comes to a pair of unbreakable glasses, we need to know the unbreakable glasses frame and unbreakable lenses. While they are often sold together, it sometimes makes sense to take them into separately consideration.

When it comes to unbreakable glasses frames, frame material is important because various materials perform differently. Some are light, and some are heavy; some flex while others break and some corrode or weaken over time. Some metals used in eyeglasses frames can also cause allergic reactions in some people. So choosing the right material can be a matter of personal health. Regarding to unbreakable glasses, the frame materials should be titanium/memory metal. They are lightweight, durable, bendable and flexible and corrosion resistant. So many people would choose titanium or memory metal frames.

When referring to unbreakable lenses, polycarbonate lenses are best choice. Polycarbonate is a moldable, durable, and inexpensive from of plastic. Polycarbonate lenses have significant benefits over the forms of lenses on the market. In addition to their excellent impact resistance, polycarbonate glasses are up to 40% thinner and one-third lighter than standard plastic lenses. These properties make polycarbonate glasses ideal for people with high prescriptions. Polycarbonate glasses, however, are not perfect. As a result of their ability to absorb impact, the lenses are soft and therefore more susceptible to scratches. To compensate for this, scratch-resistant coatings have been developed and can be added to polycarbonate glasses to provide added durability. All safety eye wear is made from polycarbonate material as it provides the best impact resistance of any eyeglass materials available. Polycarbonate glasses are 10 times more resistant to breakage than plastic lenses. Lenses made of polycarbonate are unbreakable glasses for kids witch is highly recommended due to this safety benefit. Additionally, polycarbonate blocks 99% of UV light. This ability is an important feature, especially for children and individuals who work outdoors, as UV light is known to contribute to the development of cataracts.

Eyeglasses for vision correction are needed by a large number of people in the world. They come in a wide variety of styles and countless models. Before reaching a certain age, people who have a visual refractive error or presbyopia will continue to suffer deteriorating eyesight. In this case, it is an inevitable action to buy new lenses if they use prescription eyeglasses. The practice is similar if vision-defected individuals use prescription contact lenses. This need for a higher degree of vision correction will occur especially in the first years after getting a vision problem. This has been widely complained by lots of people. And a small group of eye care doctors even believe that the use of Rx eyewear or contacts is the root cause of the deteriorating eyesight. Regardless of the correctness of this saying, unbreakable glasses are a natural and popular choice among most eyewear users.

The reason for unbreakable eyewear’s extreme popularity is that a durable frame can continue to function even if the lenses should be replaced by heavier ones. In most cases, Rx eyewear users in their 10s and 20s need to have their lenses replaced every year. This is because the old lenses can no longer provide adequate vision correction due to the poorer eyesight. Buying new lenses frequently means much expense. However, this is largely indispensible for clear vision is a necessary condition in lots of tasks. For people who have not an adequate budget for eyeglasses, choosing a durable frame is a good choice. A pair of unbreakable glasses can last several years until it is too old to use. Even if the lenses have been replaced for several times, the durable frame can hold the lenses stably and function well.

The selection of unbreakable glasses depends mainly on the frame material. Eyeglass and sunglass frames can be made of metals, plastics as well as unusual materials like horn and leather. Some of them can hardly be considered durable. Most plastics are flexible enough, but are not durable. One category of materials includes memory metal and memory plastic. These are really advanced materials featuring extreme durability. Moreover, titanium and related alloys are also good options.
