Let’s discuss the benefits of Phoenix versus polycarbonate. The one who wins is you. So, if this is the case, just get the cheapest option as results will be less than ideal in either material. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses. Multifocals and progressive lens varieties are available in polycarbonates. 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. The majority of your Rx is your astigmatism which at axis ~180 means all the thickness will be vertical. Trivex and Polycarbonate lenses are the two best choices for your child’s eyeglasses frames, sunglasses, and protective sports eyewear. Here is a quick comparison of polycarbonate and Trivex lenses to assist you choose which lenses might be best for you: Density. When compared to other lens materials, high-index nor polycarbonate are known to provide the ultimate in optical clarity. Poly had a worse abbe value meaning the color aberration is higher and trivex is clearer. Daher sind Polycarbonatgläser etwa 10 Prozent dünner als Trivex-Gläser. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! Aspheric Lenses: Design gives several advantages to eyeglass lenses. Trivex vs Polycarb. 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). Trivex has many benefits lending to its recent popularity. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. Products formed include phenyl salicylate, dihydroxybenzophenone groups, and hydroxydiphenyl ether groups. Like polycarbonate, Trivex is considered a mid-index material and has inherent UV protection. 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.
