Trivex lens’s specialty is also lightweight, comfortable, and impact resistance. The higher the number, the thinner and lighter the lens. Trivex Lens Material vs. Polycarbonate Lenses Polycarbonate and Trivex are common lens types used for children’s eyewear, safety glasses, and sports eyewear. These are thinner and lighter than the traditional eyeglass frames. 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 Trivex, like polycarbonate, has superior impact resistant qualities. Trivex Lenses vs polycarbonate lenses. Trivex Lenses: Is a relatively new material that is similar to polycarbonate lenses but with higher quality optics, and thus provides clearer vision. I have always heard that Costa glass lenses (580g) are clearer than their polycarbonate lenses (580p). I generally recommended people with prescriptions anywhere between +/-0.50 to +/-4.00 to go with polycarbonate lenses. The real winners are materials such as Trivex, CR-39 and Crown Glass. +91-9711115191 [email protected] om If thinness is important to you, then you should consider these other two alternatives. It was not until 1953 that research began to commercialize the material. Trivex Lenses vs polycarbonate lenses. Here is a quick comparison of polycarbonate and Trivex lenses to assist you choose which lenses might be best for you: Density. Polycarbonate looked like a champ amongst lens offerings. Trivex is the preferred alternative to polycarbonate when the lightness of your lens … In fact, breaking a thin polycarbonate lens would require bending it back and forth several times. The lower numbers are classified as mid-index lenses. Trivex became the only material to pass the FDA impact resistance test as a lens material besides polycarbonate in 2001. Trivex Lenses. Both lenses have comparable impact resistance and offer 100% UVA/B protection. 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. Like polycarbonate, they are thinner (by 20%) and lighter than standard plastic lenses and offer excellent impact resistance. Trivex has a slightly lower refractive index (1.53 compared to 1.59). Additionally, if you have a stronger than average prescription you may wish to invest in Trivex to avoid annoying abnormalities in your daily vision, such as haloed lights or a distorted peripheral vision. It would seem the Trivex is only a tiny step up from basic plastic lenses (1.50) when it comes to wearing bottle caps or not. Polycarbonate also suffers from an Abbe value of only 30, meaning lens distortion can be a factor for some. Polycarbonate or Trivex are the most protective eyeglass frmaes. In addition to standard Trivex®, Zenni also offers Blokz ™ Trivex ® Blokz ™ Trivex ® is a superior impact-resistance lens that is designed for all-day wear and protection from blue light. Just like the 1.53 mid-index Trivex and 1.59 polycarbonate lenses, the 1.74 lens cannot be tinted. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. Yet its specific gravity made it the lightest of any lens material. Like polycarbonate, lenses made of Trivex are thin, lightweight but are even more impact-resistant than polycarbonate. Thickness. Everything that I'm finding is that Trivex is at a 1.53 compared to 1.58 Poly. A 36-year-old member asked: are polycarbonate lenses helpful? In 2001 a rival lens material called Trivex was developed. And note that polycarbonate lenses, which are natural UV blockers, offer 100 percent protection, as do many high-index lenses, Vitale says. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. Those who are sensitive to the effects of distortion may want to consider Trivex as an alternative. 51 years experience Ophthalmology. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. It’s unavailable as a polarized or photochromic lens. When compared to other lens materials, high-index nor polycarbonate are known to provide the ultimate in optical clarity. Trivex Lenses vs polycarbonate lenses In situations where clarity is key, you may wish to invest in Trivex lenses for their higher Abbe value, and so increased visual clarity. Trivex Lenses. Trivex lenses ($200 for single vision, $400 for progressives) are more scratch-resistant than either CR-39 or polycarbonate lenses. When to Use Polycarbonate. Trivex Lenses vs polycarbonate lenses. Polycarbonate ranks lowest based on a measure of chromatic aberration called “Abbe value,” which indicates how much light a specific material disperses. Most lenses in glasses today are made of CR-39 plastic, or very close copies (since the material is owned by PPG). 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. However, some people complain that polycarbonate lenses fail to give them the crispest, clearest vision. Originally used by the military for fighter jet windshields and other military applications, Trivex is famously one of the most durable materials on the market. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! 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. However, today I was at an optical store where they said if you order 580p prescription lenses (which I do need Rx) that the polycarbonate lenses are “Trivex” (something that is not available in the non-prescription polycarbonate lenses). licensed opticians will always advise you individually on the best choice between Trivex or Polycarbonate for your kid’s eyewear lenses. Dr. Richard Bensinger answered. That means that Trivex NXT lenses are about 10 percent thinner and a bit lighter than polycarbonate lenses.
