polycarbonate lenses vs trivex

Trivex Lens Material vs. Polycarbonate Lenses Polycarbonate and Trivex are common lens types used for children’s eyewear, safety glasses, and sports eyewear. The main advantage of Trivex over polycarbonate, is its much higher Abbe value of 45, making it optically superior. And note that polycarbonate lenses, which are natural UV blockers, offer 100 percent protection, as do many high-index lenses, Vitale says. 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. Trivex lenses were created by PPG Industries to be a direct competitor to polycarbonate lenses. 51 years experience Ophthalmology. Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex. In addition, Trivex also has standard UV protection. Polycarbonate also suffers from an Abbe value of only 30, meaning lens distortion can be a factor for some. It is lighter and more scratch resistant and has high-impact resistance like Polycarbonate. Trivex is the preferred alternative to polycarbonate when the lightness of your lens … Trivex lenses ($200 for single vision, $400 for progressives) are more scratch-resistant than either CR-39 or polycarbonate lenses. 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. I generally recommended people with prescriptions anywhere between +/-0.50 to +/-4.00 to go with polycarbonate lenses. 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. Hopefully these facts arm you with a bit more information about the qualities – and distinctions – of Trivex and polycarbonate lenses.

Polycarbonate lenses also provide you with protection from 100% of the harmful UV rays from the sun. Trivex is stronger, lighter and more impact resistant than polycarbonate, making it the perfect lens for outdoor adventures. A 36-year-old member asked: are polycarbonate lenses helpful? Polycarbonate lenses have an index of refraction of 1.59, and will generally be about 20% thinner than standard plastic lenses. Opticians recommend these types of plastics because of their UV protection and high-impact resistance. The material is so durable that Trivex lenses are made exceptionally thin. Trivex Lenses vs polycarbonate 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). Most lenses in glasses today are made of CR-39 plastic, or very close copies (since the material is owned by PPG). Trivex vs. Polycarbonate: A Quick Side-By-Side Comparison. Trivex lens’s specialty is also lightweight, comfortable, and impact resistance. Polycarbonate or Trivex are the most protective eyeglass frmaes. Trivex Lenses. I have always heard that Costa glass lenses (580g) are clearer than their polycarbonate lenses (580p). 1. Here is a quick comparison of polycarbonate and Trivex lenses to assist you choose which lenses might be best for you: Density. However, polycarbonate is 10% thinner than Trivex. Both lenses have comparable impact resistance and offer 100% UVA/B protection. TRIVEX Trivex, like polycarbonate, has superior impact resistant qualities. 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. Trivex Lenses. Like polycarbonate, they are thinner (by 20%) and lighter than standard plastic lenses and offer excellent impact resistance. 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. 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. However, some people complain that polycarbonate lenses fail to give them the crispest, clearest vision. Trivex Lenses vs polycarbonate lenses. 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. The lower numbers are classified as mid-index 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. However, to most wearers, the most important choice tends to be the lens clarity. Not a huge difference, but, to some, these things matter – with polycarbonate lenses coming in around 10% thinner. Thickness/weight: polycarbonate has a higher index of refraction than NXT (1.58 vs. 1.53) and a lower specific gravity than polycarbonate. Like the 1.61 and 1.67 high-index lenses, it has an aspheric surface, improving the wearer’s visual quality while … Our A.B.O. Trivex is an improvement over Polycarbonate. Polycarbonate vs. Trivex Lenses: A Quick Comparison. 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. Believe it or not, polycarbonate was first discovered almost 120 years ago by German scientist Alfred Einhorn. Weight. 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. When compared to other lens materials, high-index nor polycarbonate are known to provide the ultimate in optical clarity.
