trivex vs polycarbonate reddit

Gewicht. Trivex® lenses are impact resistant and more lightweight than standard lenses. It has better optics than poly and doesn’t scratch as easily, while still being impact and shatter resistant. In 1970, polycarbonate was refined from a brownish tint into a clear material used today in many safety glasses. Like polycarbonate, lenses made of Trivex are thin, lightweight but are even more impact-resistant than polycarbonate. 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. Polycarbonate and Trivex lenses provide greater impact resistance than lenses made out of other materials. Once a patient gets to a very high Rx then maybe Trivex might (might!) Both polycarbonate and Trivex lenses are thinner and lighter than regular plastic lenses. Because of less internal stress, Trivex produces a clear central vision than polycarbonate. You suggest I go poly then? Polycarbonate is a specific kind of plastic invented in 1953 by Bayer’s Dr. Hermann Schnell and General Electric’s Dr. Daniel Fox. Thing is I already have the frames haha. 2. 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. Trivex lenses are made from a lightweight, impact-resistant material. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. The tops of your frames might have a little bit of thickness with Trivex. One thing that hadn't been mentioned is aberration value. The Difference: The key difference that sets the two materials apart however, insofar as providing an optimum eyewear experience, is that Trivex lenses have a higher ABBE LEVEL. High-Index. How does Trivex compare to polycarbonate? What follows is a side by side comparison of the two lens materials to determine how they weigh up against one another. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! The one who wins is you. Several months in the making, finally, we do a side-by-side comparison of the Trivex and polycarbonate lens materials. 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. If you're going to be racing, hiking, or running, you don't want to feel the sunglasses on your face. By 1978 the first single vision ophthalmic lenses were being produced. Poly is last choice in most circumstances in my office. And yes trivex is a higher refractive index meaning the lens is thinner than a traditional poly. The thinnest and lightest eyeglass lenses are the high-index lenses, such as 1.66 and 1.74. When you find the article helpful, feel free to share it with your friends or colleagues. Like the 1.61 and 1.67 high-index lenses, it has an aspheric surface, improving the wearer’s visual quality while reducing distortion of the wearer’s eyes as seen by others. Technology is evolving, and like any new material that appears, trivex lenses bring an addition to the older polycarbonate eyeglass lenses. While it’s slightly lighter than polycarbonate, it also has a slightly lower index of refraction. Trivex hands down. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses. Believe it or not, polycarbonate was first discovered almost 120 years ago by German scientist Alfred Einhorn. My opinion on Trivex vs poly has generally been that 99% of the time the difference is going to be negligible to the patient and the only real difference is going to be in the lab work. Dabei gibt es zwei unterschiedliche Konstruktionsprinzipien. Trivex and polycarbonate are indeed the “kissing cousins” of the safety eyewear industry, but they do have a few differences that can help you decide which one is better suited for your particular needs. 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.

Creators use a mold to construct the lenses in much the same way regular plastic lenses for glasses are made. Polycarbonate Lenses. Thanks, I'll likely get Trivex. This makes it a good choice for rimless glasses, because drilling holes into the lenses won’t create hairline cracks like with polycarbonate. The DR I spoke to sent me to the ER then we saw our normal vet the next day who did emergency surgery or a strangulated hernia and she's now fine. NXT lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality. Trivex is a more rigid material, making it a better selection for rimless or drill mount frames. Otherwise a real optician would have been able to easily explain this. 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.
