Everything that I'm finding is that Trivex is at a 1.53 compared to 1.58 Poly. 51 years experience Ophthalmology. It was not until 1953 that research began to commercialize the material. Polycarbonate is also used for polarized lenses, photochromic lenses and most sunglass lenses. The higher the number, the thinner and lighter the lens. Polycarbonate lenses have an index of refraction of 1.59, and will generally be about 20% thinner than standard plastic lenses. Trivex Lens Material vs. Polycarbonate Lenses Polycarbonate and Trivex are common lens types used for children’s eyewear, safety glasses, and sports eyewear. Hopefully these facts arm you with a bit more information about the qualities – and distinctions – of Trivex and polycarbonate lenses. Polycarbonate or Trivex are the most protective eyeglass frmaes. Trivex Lenses. 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). TRIVEX Trivex, like polycarbonate, has superior impact resistant qualities. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. What are Trivex Lenses? 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 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. And note that polycarbonate lenses, which are natural UV blockers, offer 100 percent protection, as do many high-index lenses, Vitale says. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. Plastic Lenses (CR-39) Plastic lenses or also known as CR-39 is the most common optical lens material you will find. lenses, sport lenses and safety lenses. Dr. Richard Bensinger answered. And Then Came Poly Polycarbonate is still lighter, and can be made in higher index – meaning that a strong prescription lens can still be quite thin. These are thinner and lighter than the traditional eyeglass frames. Trivex lenses ($200 for single vision, $400 for progressives) are more scratch-resistant than either CR-39 or polycarbonate lenses. They can be useful if … Trivex Lenses: Is a relatively new material that is similar to polycarbonate lenses but with higher quality optics, and thus provides clearer vision. Polycarbonate vs. Trivex Lenses: A Quick Comparison. In fact, breaking a thin polycarbonate lens would require bending it back and forth several times. Trivex became the only material to pass the FDA impact resistance test as a lens material besides polycarbonate in 2001. Trivex has a slightly lower refractive index (1.53 compared to 1.59). Most lenses in glasses today are made of CR-39 plastic, or very close copies (since the material is owned by PPG). However, polycarbonate is 10% thinner than Trivex. Not a huge difference, but, to some, these things matter – with polycarbonate lenses coming in around 10% thinner. 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. That means that Trivex NXT lenses are about 10 percent thinner and a bit lighter than polycarbonate lenses. Like the 1.61 and 1.67 high-index lenses, it has an aspheric surface, improving the wearer’s visual quality while … Trivex® tri-performance lens material by PPG is a breakthrough optical polymer that offers the impact resistance of polycarbonate with excellent optics equal to CR-39 and glass. The material is so durable that Trivex lenses are made exceptionally thin. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex. Polycarbonate vs. Trivex Eyeglass Lenses Sunday, December 3, 2017 2:22:57 PM America/New_York. In addition, Trivex also has standard UV protection. Polycarbonate lenses also provide you with protection from 100% of the harmful UV rays from the sun. I generally recommended people with prescriptions anywhere between +/-0.50 to +/-4.00 to go with polycarbonate lenses. Like polycarbonate, lenses made of Trivex are thin, lightweight but are even more impact-resistant than polycarbonate. The cast molding process is included the same as in plastic lenses making. 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. 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. +91-9711115191 [email protected] om Trivex Lenses vs polycarbonate lenses. 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. Opticians recommend these types of plastics because of their UV protection and high-impact resistance. Believe it or not, polycarbonate was first discovered almost 120 years ago by German scientist Alfred Einhorn. 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. Yet its specific gravity made it the lightest of any lens material. Trivex. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. 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. In this area, Trivex wins hands-down. Trivex lenses are composed of a urethane-based monomer and are made from a cast moulding process similar to how regular plastic lenses are made. Weight. 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. Both lenses have comparable impact resistance and offer 100% UVA/B protection. Just like the 1.53 mid-index Trivex and 1.59 polycarbonate lenses, the 1.74 lens cannot be tinted. 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. Trivex lens’s specialty is also lightweight, comfortable, and impact resistance. 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. Trivex Lenses. Polycarbonate has a good amount of flexibility. How They Are Made. trivex lenses vs polycarbonate. Our A.B.O. Polycarbonate Lenses. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses. The real winners are materials such as Trivex, CR-39 and Crown Glass. Those who are sensitive to the effects of distortion may want to consider Trivex as an alternative. 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. Weight. 1. Polycarbonate looked like a champ amongst lens offerings. 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. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. The lower numbers are classified as mid-index lenses. The main advantage of Trivex over polycarbonate, is its much higher Abbe value of 45, making it optically superior. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. If thinness is important to you, then you should consider these other two alternatives. Usually, 3M Safety Glasses are made by Trivex and polycarbonate lenses.
