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. Polycarbonate and Trivex lenses provide greater impact resistance than lenses made out of other materials. And yes trivex is a higher refractive index meaning the lens is thinner than a traditional poly. 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. 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). It’s very low specific gravity, however, can make it as lightweight as many high index materials for a lower cost. This video explains some of the differences between trivex and poly. Trivex also has a higher tensile strength. NXT has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a specific lens material. You suggest I go poly then? In 1970, polycarbonate was refined from a brownish tint into a clear material used today in many safety glasses. Trivex is just as impact resistant as polycarbonate and may also be prescribed for children’s lenses, sport lenses and safety lenses. NXT lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality. Further distinguishig itself, Trivex is ideal for drill mounting. Otherwise a real optician would have been able to easily explain this. The biggest pro compared to polycarbonate is Trivex’s Abbe value. 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. If you are looking for more variety in terms of design, the range is wider in polycarbonate lenses. Polycarbonate. Not to mention, Trivex resistance to stress and cracking makes for a durable lens material when it comes to combatting the normal wear and tear sunglasses experience in everyday life. read this article we found about eye glass lenses: Even though Trivex has been available for a while now, there is still much debate and confusion about how Trivex and polycarbonate stack up against one another. This makes it a good choice for rimless glasses, because drilling holes into the lenses won’t create hairline cracks like with polycarbonate. The real winners are materials such as Trivex, CR-39 and Crown Glass. 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 NXT® are up to 10 times more impact-resistant than glass, plastic, TAC or CR39 lenses. Trivex vs. Polycarbonate. Was ist schusssicheres Polycarbonat-Glas? Because of less internal stress, Trivex produces a clear central vision than polycarbonate. I would definitely recommend trivex over poly as well. Trivex vs. Polycarbonate. A free-form lens with POW measurements will be even better for your type of Rx. read this article we found about eye glass lenses: Even though Trivex has been available for a while now, there is still much debate and confusion about how Trivex and polycarbonate stack up against one another. Trivex also has a slightly lower density so it is lighter than polycarbonate. Or is risking a little bit of edge thickness worth the clarity? Polycarbonate vs. Trivex History Polycarbonate: This material was developed during the “space race” of the late 1960’s. 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. But, Trivex has a lower index of 1.53, Poly is 1.59. This is because they are made up of a urethane-based monomer, which refracts less light. The thickness of individual material. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. In fact, Trivex is the lightest weight lens material available. I assume you are getting lenses online or from a box/chain store who employ sales clerks and not opticians. Both lenses are lighter and thinner than others like glass and plastic. Trivex will be a more optically clear lens and with your astigmatism will be more important. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. Trivex is an improvement over Polycarbonate. The reaction can be propagated via side chain oxidation, ring oxidation or photo-Fries rearrangement. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. 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. Posted on September 6, 2013 by adveyecarecnter. Thanks, I'll likely get Trivex. The only negative to Trivex versus polycarbonate is the lower index of refraction (1.53 vs 1.58) which means Trivex lenses will be slightly thicker than polycarbonate. Be cause of its clarity, durability, ultra-lightweight properties, and resistance to chemicals, Trivex is used in production for helicopter and fighter jet canopies As a result of the success in military aircraft platforms, this high-quality material was brought to the eyewear industry in the early 2000s.

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. Durchschusshemmendes Glas, welches aus Glas und Polycarbonat besteht, wird auch als schusssichere Polycarbonat-Verglasung bezeichnet. Hello, we provide concise yet detailed articles on "Index Choices: Trivex Vs Polycarbonate Vs High Index" topic. High-Index. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10% lighter as a result. Polycarbonat hat einen höheren Brechungsindex als Trivex (1, 58 vs. 1, 53). Weight. Other opticians claiming poly is garbage and being dramatic about how terrible it is has always been a red flag to me that they're a terrible optician. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. 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. Once a patient gets to a very high Rx then maybe Trivex might (might!) Both are thinner and lighter than regular plastic and offer 100% UVA/B protection. When you find the article helpful, feel free to share it with your friends or colleagues. Gewicht. Aspheric Lenses: Design gives several advantages to eyeglass lenses.
