Opticians recommend these types of plastics because of their UV protection and high-impact resistance. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. They can be useful if … 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. Polycarbonate also suffers from an Abbe value of only 30, meaning lens distortion can be a factor for some. Just like the 1.53 mid-index Trivex and 1.59 polycarbonate lenses, the 1.74 lens cannot be tinted. Usually, 3M Safety Glasses are made by Trivex and polycarbonate lenses. 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. lenses, sport lenses and safety lenses. Weight. Trivex is an improvement over Polycarbonate. 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 were created by PPG Industries to be a direct competitor to polycarbonate lenses. +91-9711115191 [email protected] om These are thinner and lighter than the traditional eyeglass frames. Trivex. 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. Most lenses in glasses today are made of CR-39 plastic, or very close copies (since the material is owned by PPG). Trivex lenses ($200 for single vision, $400 for progressives) are more scratch-resistant than either CR-39 or polycarbonate lenses. Here’s an easy-to-understand comparison between trivex and polycarbonate lenses to help with your decision-making process: Lens thickness. On the other hand, a Trivex lens is marginally thicker than a polycarbonate lens in any given prescription. Dr. Richard Bensinger answered. trivex lenses vs polycarbonate. In 2001 a rival lens material called Trivex was developed. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. Trivex is the preferred alternative to polycarbonate when the lightness of your lens … 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. Weight. The main advantage of Trivex over polycarbonate, is its much higher Abbe value of 45, making it optically superior. 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. Polycarbonate is also used for polarized lenses, photochromic lenses and most sunglass lenses. However, to most wearers, the most important choice tends to be the lens clarity. In fact, breaking a thin polycarbonate lens would require bending it back and forth several times. Trivex Lenses vs polycarbonate 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 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.
