Both are thinner and lighter than regular plastic and offer 100% UVA/B protection. Trivex is a material developed in the 1990s originally for military use. Let’s discuss the benefits of Phoenix versus polycarbonate. In most cases, there is no wrong choice here. Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses. Trivex vs Polycarb. So I've been given a choice. It was developed in 2001 by PPG Industries as an alternative to polycarbonate. Optical clarity (central). 2. So if you’ve got your eye on that style, we strongly recommend Trivex. Thickness: Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses, but as you see in the video, the difference may not even be noticeable. For starters, here are the statistics for each format: TRIVEX. It was used for helmets and visors for astronauts. The reaction can be propagated via side chain oxidation, ring oxidation or photo-Fries rearrangement. Was ist schusssicheres Polycarbonat-Glas? Thickness: Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses, but as you see in the video, the difference may not even be noticeable. A quick comparison between Trivex and polycarbonate: Polycarbonate lenses are thinner than Trivex because of higher index of refraction. Trivex has the same advantages as polycarbonate such as 100% protection against UV and superior impact strength. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. Trivex is an improvement over Polycarbonate. Poly and Trivex: Facts and Fiction Even though Trivex has been available for years and polycarbonate for decades, there is still much debate, confusion and even long-held myths about how Trivex and polycarbonate stack up against one another. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. Because of less internal stress, Trivex produces a clear central vision than polycarbonate. Polycarbonat hingegen wird durch Beschichtung oder das Laminieren mit Glas UV-geschützt.

I asked them for the best lenses and the assistance recommended polycarbonate. The refractive index of a material is a number that measures how well the material refracts and bends light, which depends on how fast light travels through the material. Like polycarbonate, lenses made of Trivex are thin, lightweight but are even more impact-resistant than polycarbonate. Gewicht. It was not until 1953 that research began to commercialize the material. The information here is sourced well and enriched with great visual photo and video illustrations. But, Trivex has a lower index of 1.53, Poly is 1.59. The big advantage of Trivex over polycarbonate is its better optical quality, which means your vision is sharper. High index plastic generally has a lower Abbe number than Trivex, meaning that Trivex is more optically clear and causes less distortion than high index plastic. Interesting video I found comparing the two materials. They are made out of softer plastic compounds which makes them less brittle than other lenses and, consequently, able to absorb impacts without cracking, fracturing or shattering. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. Trivex vs. Polycarbonate. Or is risking a little bit of edge thickness worth the clarity? Trivex Polycarbonate 1.60 index 1.67 index Human eye 59/59 56 45 30 42 32 45 Eyecare professionals have long sought to understand the exact nature of the vision-degrading effects of low Abbe value, and how they can calculate at what point Abbe will have a negative impact on a person’s acuity or contrast sensitivity. One thing that hadn't been mentioned is aberration value. With Phoenix (Trivex) lenses, you don’t have to sacrifice visual quality. NXT lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality. Lenses made from Trivex are ultra-light in weight, much more resistant to cracking and breaking and have better optics than polycarbonate thanks to much better control of chromatic aberrations. Trivex also has a slightly lower density so it is lighter than polycarbonate. Thanks. In 1970, polycarbonate was refined from a brownish tint into a clear material used today in many safety glasses. NXT has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a specific lens material. Creators use a mold to construct the lenses in much the same way regular plastic lenses for glasses are made. Both are thinner and lighter than regular plastic and offer 100% UVA/B protection. Trivex lenses vs. Polycarbonate Eyeglass Lenses. Poly is also much easier long term on your grinding wheel or blade from what I've been informed when I worked in a lab and from when I bought my edger. Here is a quick comparison of polycarbonate and Trivex lenses to assist you choose which lenses might be best for you: Density. Trivex is a more rigid material, making it a better selection for rimless or drill mount frames. Trivex will be $50 more, and I've heard some people actually have problems with Polycarb. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. Between poly and trivex, trivex is definitely the better material. By using our Services or clicking I agree, you agree to our use of cookies. It’s unavailable as a polarized or photochromic lens. Polycarbonat vs. Trivex-Linsen: Ein schneller Vergleich . It has better optics than poly and doesn’t scratch as easily, while still being impact and shatter resistant. However, unlike polycarbonate, Trivex has an Abbe value of 45, making it optically superior. Trivex is more impact resistant than high index plastic, making it a much better choice for safety glasses or other types of glasses that need to meet certain impact requirements. Trivex is lighter in weight than standard plastic but not quite as thin as polycarbonate. Polycarbonate Lenses vs Trivex Lenses What are polycarbonate lenses? Also, it’s the second most impact-resistant lens available, just down a notch on impact resistance from the 1.53 Trivex lens, making it a good, less-expensive alternative for rimless, children’s, and sports eyeglasses. Trivex also has a higher tensile strength. With your script, I would probably recommend poly or trivex (though honestly depending on your frame choice you could probably get away just as well with CR39 plastic). While it’s slightly lighter than polycarbonate, it also has a slightly lower index of refraction. We’ll lay out the facts and attempt to put the question to rest. What follows is a side by side comparison of the two lens materials to determine how they weigh up against one another. In … Once a patient gets to a very high Rx then maybe Trivex might (might!) The thinnest and lightest eyeglass lenses are the high-index lenses, such as 1.66 and 1.74. Posted on September 6, 2013 by adveyecarecnter. However, Trivex lenses have a much higher abbe value (43-45) vs. polycarbonate (abbe value 30) making it much better in optical clarity with fewer chromatic aberrations.
