You have probably noticed the huge amount of trendy glasses in the crowd. This can be attributed to the very recent trend of so-called hipster or nerd glasses. Today we are going to discover the world of numerous materials to design and produce spectacle frames. Generally speaking, there are three major groups of frames materials when it comes to eyewear production: plastic frames, metal frames and special frames. We will try to go through every group one by one discovering advantages, possible issues and latest fashion trends. But for the time being, let me concentrate on plastic materials.
Plastic Frames: Be Creative By Choosing Any Color You Want
Thanks to the many different eyeglass frame materials available in the market nowadays, you currently have a lot of options to revamp your look. So, when shopping for new sunglasses or eyeglasses, you might want to ask your optician what your options are in terms of colors, lightness, durability, brands, uniqueness, price and hypoallergenic materials before making your final decision.
Overall, though, finding eyeglasses with all of the traits that you find most important could simply lie in finding the perfect material for you – one that has the unique strengths that you need for your glasses. Generally speaking, spectacle frame materials have two main categories: plastics and metals. Here, we will focus on plastic frames.
SPX refers to the lightest plastic material that can be used to make spectacle frames out there. Despite its light weight, though, it is known to be very strong overall. Plus, it is hypo-non-allergenic and very resistant to perspiration absorption at the same time. As such, it can also retain its luster and color quite well. The best part is that SPX comes in various finishes, too.
SPX can be quite hard to adjust as time goes by, though, since it tends to get very brittle in colder weather and tends to shrink with age, as well. Sometimes, this could make removing the lenses very hard without actually breaking the frames. This is why SPX frames shouldn’t be reglazed at all. If it absolutely has to be done, though, then you must do so at your own risk.
Optyl is very light yet very durable, too. It is also known to be a top quality plastic and is available in both translucent and solid colors to suit your preferences. Aside from that, it can also resist perspiration and retain its shape quite well.
Optyl is basically a cast-molded thermosetting plastic, which means that it can stay in a certain shape until it experiences very high temperatures. In extreme heat, it may soften and be re-shaped into new adjustment shapes as needed, as well. The reshaping will need to be done during its cool-down, though. So, while optyl can be tricky to adjust overall, it can be very useful as a material since it can retain any adjusted shape forever.
Nylon eyeglasses were first introduced in the 1940s. However, because of certain problems related to them, such as their brittleness, a lot of eyeglass manufacturers started using blended nylon to make eyeglasses instead. Nowadays, these blended nylon frames are considered to be both lightweight yet strong.
Nylon also works well for performance and sports frames, which usually consist of trogamid, gliamides or grilamid materials that are resistant to different temperatures, and are stiff yet flexible at the same time. Nylon is also easy to mold into wraparound styles and other shapes that are popular nowadays.
Carbon fibre frames are generally made of plastic that is reinforced with carbon fibres and metal on the sides to make it stronger despite its light weight.
You have to be careful of carbon fibre frame coatings, though, because they tend to come off when their wearers perspire a lot. While expensive versions don’t really suffer from this problem, it may be best to steer clear of carbon fibre altogether if you know that you sweat a lot.
Glass fibre can be quite hard to adjust if it isn’t perfectly made as needed.
If you want to have all of the colors of the rainbow available to you, then cellulose acetate would be the perfect material for this. Cellulose acetate isn’t just very cost-effective overall, either; it is also a creative and lightweight option for eyewear, in general. Laminated cellulose acetate frames with layered colors are quite popular nowadays, for one, and look best when the light colors are inside. All-black frames are good options, too, though.
There are several drawbacks that come with plastic frames, though. For starters, they are much easier to break compared to metal frames, and they can burn if ignited, too. Aside from that, sunlight exposure and time can make them weaker, as well. Their colors may also fade as time goes by, though not as much as the way colors fade in more modern materials.
