Trivex hands down. That means that Trivex NXT lenses are about 10 percent thinner and a bit lighter than polycarbonate lenses. So here it is from the people who know.

Ps. 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. 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. Trivex vs. Polycarbonate. Trivex®, manufactured by PPG, is a clearer material than the industry standard polycarbonate. If you are looking for more variety in terms of design, the range is wider in polycarbonate lenses. Trivex is a material developed in the 1990s originally for military use. 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. Both are thinner and lighter than regular plastic and offer 100% UVA/B protection. Multifocals and progressive lens varieties are available in polycarbonates. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! 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). Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. A free-form lens with POW measurements will be even better for your type of Rx. Polycarbonate vs. Trivex History Polycarbonate: This material was developed during the “space race” of the late 1960’s. 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. How does Trivex compare to polycarbonate? Trivex lenses are made from a urethane-based monomer. High-Index. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. Interesting video I found comparing the two materials. Is also fun to see this as a bit of evidence that I'm not crazy for trying to think reasonably. Otherwise a real optician would have been able to easily explain this. Trivex® lenses are impact resistant and more lightweight than standard lenses. Weight. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. 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. We added special dyes to Trivex during the manufacturing process that increases the contrast between colors making them seem brighter. Trivex vs. Polycarbonate: A Quick Side-By-Side Comparison. The real winners are materials such as Trivex, CR-39 and Crown Glass. Polycarbonate molecules (such as the aromatic ring) absorb UV radiation. 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 and Polycarbonate lenses are the two best choices for your child’s eyeglasses frames, sunglasses, and protective sports eyewear. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. Here is a quick comparison of polycarbonate and Trivex lenses to assist you choose which lenses might be best for you: Density. Sphere: -1.25 Cyl: -2.75 Axis: 173.

And yes trivex is a higher refractive index meaning the lens is thinner than a traditional poly. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. 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. Polycarbonate or Trivex are the most protective eyeglass frmaes. Polycarbonat hingegen wird durch Beschichtung oder das Laminieren mit Glas UV-geschützt. 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. Trivex is an improvement over Polycarbonate. Ultraviolet treatment uses a dye to tint glasses to block harmful UV rays. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10% lighter as a result. High-Index. By 1978 the first single vision ophthalmic lenses were being produced. Thing is I already have the frames haha. Polycarbonate. The comparison is based on the features of Trivex and 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. While it’s slightly lighter than polycarbonate, it also has a slightly lower index of refraction. Let’s discuss the benefits of Phoenix versus polycarbonate. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. Both materials are excellent choices, with a plus for trivex eyeglass lens, especially the quality of vision and resistance, but also with a higher price. I would go with trivex just from a visual quality since poly doesn't do well for me. Creators use a mold to construct the lenses in much the same way regular plastic lenses for glasses are made. We’ll lay out the facts and attempt to put the question to rest. Trivex Lenses vs polycarbonate lenses.
