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. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. 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. Trivex vs. Polycarbonate: A Quick Side-By-Side Comparison. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. 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 lens’s specialty is also lightweight, comfortable, and impact resistance. The material is so durable that Trivex lenses are made exceptionally thin. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. Polycarbonate vs. Trivex Lenses: A Quick Comparison. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. In addition, Trivex also has standard UV protection. 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. When to Use 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. Trivex Lenses. 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. 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. On the other hand, a Trivex lens is marginally thicker than a polycarbonate lens in any given prescription. Polycarbonate has a good amount of flexibility. And note that polycarbonate lenses, which are natural UV blockers, offer 100 percent protection, as do many high-index lenses, Vitale says. Trivex Lenses vs polycarbonate lenses. The higher the number, the thinner and lighter the lens. Opticians recommend these types of plastics because of their UV protection and high-impact resistance. Plastic Lenses (CR-39) Plastic lenses or also known as CR-39 is the most common optical lens material you will find. The real winners are materials such as Trivex, CR-39 and Crown Glass. TRIVEX Trivex, like polycarbonate, has superior impact resistant qualities. Trivex. When compared to other lens materials, high-index nor polycarbonate are known to provide the ultimate in optical clarity. Trivex is the preferred alternative to polycarbonate when the lightness of your lens … It was not until 1953 that research began to commercialize the material. Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex. 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. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! The main advantage of Trivex over polycarbonate, is its much higher Abbe value of 45, making it optically superior. Just like the 1.53 mid-index Trivex and 1.59 polycarbonate lenses, the 1.74 lens cannot be tinted. 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. 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. Polycarbonate lenses have an index of refraction of 1.59, and will generally be about 20% thinner than standard plastic lenses. Both lenses have comparable impact resistance and offer 100% UVA/B protection. 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. 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. Our A.B.O. 2. Polycarbonate looked like a champ amongst lens offerings. Trivex Lens Material vs. Polycarbonate Lenses Polycarbonate and Trivex are common lens types used for children’s eyewear, safety glasses, and sports eyewear. Polycarbonate lenses also provide you with protection from 100% of the harmful UV rays from the sun. Trivex Lenses: Is a relatively new material that is similar to polycarbonate lenses but with higher quality optics, and thus provides clearer vision. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. If thinness is important to you, then you should consider these other two alternatives. 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. 51 years experience Ophthalmology. licensed opticians will always advise you individually on the best choice between Trivex or Polycarbonate for your kid’s eyewear lenses. Trivex has a slightly lower refractive index (1.53 compared to 1.59). The cast molding process is included the same as in plastic lenses making. Trivex lenses ($200 for single vision, $400 for progressives) are more scratch-resistant than either CR-39 or polycarbonate lenses. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses. Believe it or not, polycarbonate was first discovered almost 120 years ago by German scientist Alfred Einhorn. Yet its specific gravity made it the lightest of any lens material. However, some people complain that polycarbonate lenses fail to give them the crispest, clearest vision. Trivex lenses were created by PPG Industries to be a direct competitor to polycarbonate lenses. Thickness. Polycarbonate or Trivex are the most protective eyeglass frmaes. 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. Weight. It’s unavailable as a polarized or photochromic lens. Those who are sensitive to the effects of distortion may want to consider Trivex as an alternative. How They Are Made. Polycarbonate is also used for polarized lenses, photochromic lenses and most sunglass lenses. trivex lenses vs polycarbonate. Trivex is an improvement over Polycarbonate. Weight. The CR stands for “Columbia Resin” which is the polymer that the material is made out of and the 39 means that there were 38 other “Columbia Resin’s” that didn’t make the cut for optical lenses. Additionally, Trivex is commonly used as a lens material because of its high-velocity impact and has been increasing in application and market availability. 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. lenses, sport lenses and safety lenses. 1. 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. I have always heard that Costa glass lenses (580g) are clearer than their polycarbonate lenses (580p). 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. These are thinner and lighter than the traditional eyeglass frames. 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). 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.
