Is Trivex stronger than polycarbonate?

Those who want to avoid scratches on the eyewear can ask for an anti-scratch coating with this type of plastic material. For older people, lenses with this characteristic can be extremely important. Once the skin on the bridge of the nose becomes finer and more sensitive, lightweight eyewear can decrease the likelihood of irritation. Both lens materials are indeed relatively close in a number of categories, but do have distinctive properties than set them apart. Since 2001, other chemical companies have already been working on formulas for materials that mimic the wonderful characteristics of Trivex. The company that has been most successful in this is KOC from South Korea.

Regular eyeglass frames aren’t rated for use as safety glasses and typically don’t supply the kind of eye protection necessary for sports. Developed by PPG Industries in 2001, Trivex lenses are lightweight and many more impact-resistant than regular plastic or glass lenses. Polycarbonate originated in the 1970s for aerospace applications. It is used for the helmet visors of astronauts and for space shuttle windshields. Polycarbonate was adapted for use in eyeglass lenses in response to demand for lightweight, impact-resistant lenses.

Can help extend the life of one’s sunglasses—because they’re an essential piece of equipment that needs to be treated as such. Performs much like polycarbonate with regard to their weight, durability index and UV protection. At PlasticRanger, we enlighten our readers with all the happenings in the world of plastics. An easy method to remove scratches from polycarbonate is to squeeze a pea-sized amount of toothpaste on a soft, clean, cotton cloth. Rub the toothpaste on the scratched surface in a circular motion continuously for seconds.
Cleaners such as Windex and alcohol are safe to use on Trivex. GlassesUSA has a huge selection of contacts, glasses, & sunglasses. Liingo Eyewear is another great option to buy glasses online. Aspheric and atoric lens designs reduce unwanted magnification and minification within more traditional eyewear. These kind of design can also increase the peripheral view by eliminating distortion. Lastly, Trivex has a lower specific gravity (1.11) to that of polycarbonate (1.66).
Trivex lenses have an increased Abbe value than polycarbonate since it is made up of a urethane-based monomer, which refracts less light. When lenses are manufactured from materials with a lesser Abbe value, a certain deviation depending is expected. Trivex lenses will undoubtedly offer better clarity and visual experience than polycarbonate lenses, because of their high ABBE value. Just like polycarbonate, Trivex had not been originally developed to be used in eyewear. It was developed remember the necessity for durable military jet windshields along with other similar military applications. In the year 2002, PPG industries developed a chemical process with material to be specifically used for eye lenses.

By 1978 the first single vision ophthalmic lenses were being produced. The following years brought improvements to resin purity, manufacturing, and lab processing. The pros of PC lenses is that they’re thin, light, and impact-resistant, making them an excellent option for sports or safety glasses. Another upside is since they’re so common, you’ll probably be able to get whichever lens features you want. Polarized, progressives, whatever you may need, there should be no trouble with a polycarbonate lens.
In 2001, PPG introduced a completely new material called Trivex. It meets all the FDA standards for safety glasses and was the only real lens material other than polycarbonate to pass FDA Impact Resistance Tests. Both popularity and option of Trivex have already been increasing slowly. Trivex has a slightly lower refractive index (1.53 compared to 1.59). Yet its specific gravity made it the lightest of any lens material.
The business then took this ultra-strong, lightweight material and applied it to consumer optical needs. However, clear vision with several safety features is important to numerous glasses wearers. So some people opt to pay out of pocket for Trivex lenses.
