Home Additionally, polycarbonate has a higher chromatic aberration with an Abbe value of 29. © Roche Industry 2021. On weight, the advantage is all in favor of trivex eyeglass lens, which is lighter than polycarbonate eyeglass lens, being even the lightest and most comfortable material used in the manufacture of lenses, that due to its lower density. The main question should always be, what the biggest priority of your lenses is. Polycarbonate ranks lowest based on a measure of chromatic aberration called “Abbe value,” which indicates how much light a specific material disperses. Hi, I'm Endre with my brother Arpi. Lot of our clients ask us which option would be better. Both materials are lighter, thinner and more resistant, than plastic and glass of course, so suitable for activities requiring eye protection against impact: Trivex is better in terms of optical quality. Despite the difference, you may not be able to notice that Trivex is ten times thicker than polycarbonate. Trivex has the impact resistance and inherent UV protection of polycarbonate. Here is what you need to know: If until now, you knew that polycarbonate is the most impact resistant, now we have newer stuff, trivex glasses with features resembling those of polycarbonate but better. In fact, breaking a thin polycarbonate lens would require bending it back and forth several times. Both materials are excellent choices, with a plus for trivex eyeglass lens, especially the quality of vision and resistance, but also with a higher price. Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex. Polycarbonate versus Trivex Lenses: A Quick Comparison. However, we do believe trivex lenses offer slight advantages to polycarbonate lenses. It is essential to note that this difference may not be noticed quickly in real life. When carrying out a test to compare Trivex and polycarbonate, you will discover that the performance differences of the two lens materials are negligible. Polycarbonate also has a high likelihood of cracking when drilled because it has a low tensile strength. In terms of thickness, polycarbonate boasts of a higher refractive index of 1.58 compared to 1.53 of Trivex. Trivex Lenses. Trivex and polycarbonate have been in existence for ages. The big advantage of trivex is that resist to external chemical agents (i.e. 0 comment. This means that polycarbonate lenses are thinner than Trivex lenses. Value—The modest up-charge ECPs see on their wholesale price lists for finished, conventionally … Tyler uses it in all his glasses because it’s the lightest lens material and is as impact-resistant, if not more so, than PC. In other words, they are not rigid and stiff. Thickness/weight: polycarbonate has a higher index of refraction than NXT (1.58 vs. 1.53) and a lower specific gravity than polycarbonate. Trivex eyeglasses are more expensive as anything is new and better. Polycarbonate was originally developed for fighter jet cockpits. It was developed in 2001 by PPG Industries as an alternative to polycarbonate. On the other hand, a Trivex lens is marginally thicker than a polycarbonate lens in any given prescription. Copyright © 2020 Perfect-Eyeglasses-Guide.Com. At SimplySafetyGlasses.com all prescription gla… The higher the number, the thinner and lighter the lens. This means that annoying chromatic aberrations are a thing of the past. This shortcoming makes it a challenge to use polycarbonate in drill-mount frames. Trivex is a great alternative to polycarbonate lenses. The flexibility of polycarbonate and Trivex means that they require protection from scratches. These are thinner and lighter than the traditional eyeglass frames. However, these differences are only notable on papers. $8-$900 later I decided to educate myself on lenses and found out trivex are … Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. Polycarbonate was first introduced to the optical world in the late ’70s as an ophthalmic lens. Our advise will be based on your child’s prescription, frame choice, and lifestyle. However, polycarbonate is 10% thinner than Trivex. Trivex traditionally costs more than double the price of polycarbonate. This feature is impacted by a higher refraction index and lower specific gravity. Trivex is 90 percent more resistant to this type of induced distortion than polycarbonate. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10% lighter as a result. You are now well-versed with some essential information about Trivex and Polycarbonate. That is because Trivex has a lower specific gravity compared to polycarbonate. Trivex and Polycarbonate lenses *naturally block* 100 percent of the sun’s UV rays without the need for special UV-blocking lens coatings. The real winners are materials such as Trivex, CR-39 and Crown Glass. Trivex® lenses are impact resistant and more lightweight than standard lenses. @@Trivex is thinner and lighter than CR39. Meanwhile, shatter resistance is also in favor of trivex. trivex lenses vs polycarbonate. In general Trivex performs similarly to polycarbonate in terms of their weight, durability index and UV protection. Polycarbonate is not only more affordable but also highly shatter resistant, which makes it ideal for use in safety and sports eyewear. A higher Abbe value due to less chromatic aberration, Trivex offers sharper peripheral … Other specifications like protection from direct UV rays make polycarbonate ideal for use in lenses. 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. We’ll lay out the facts and attempt to put the question to rest. This Trivex is a more rigid material, making it a better selection for rimless or drill mount frames. This is 40 nanometers more than untreated CR-39. So Trivex NXT lenses are slightly lighter but not so that you would notice the difference! Their strength and impact resistance makes them a great option for kids’, rimless frames, sports goggles and safety glasses, or anyone who is rough on their glasses. If thinness is important to you, then you should consider these other two alternatives. Materials with a … Both polycarbonate and Trivex have high resistance to impact. Trivex lenses are made from a lightweight, impact-resistant material. If you have the knowledge or experience that others would want, you can do the same and create a website from scratch about your hobby, using the right tools. Trivex vs. Polycarbonate. Both polycarbonate and Trivex offer 100% protection against UV rays. In most cases, polycarbonate lenses lack optical quality because they possess less clarity and transparency, like other forms of plastic such as acrylic and Trivex. If you're going to be racing, hiking, or running, you don't want to feel the sunglasses on your face. This article will down the facts about both Trivex and polycarbonate, put them to the test. It can be drilled successfully without cracking the material around drill holes. The one who wins is you. The glasses I'm using currently are hi-index plastic and while it's ok, it doesn't feel, Q: Please help. monomer (1.32), Trivex material is 16% lighter; compared to polycarbonate, it is 8% lighter, and nearly 25% lighter than ultra high index (1.66 and 1.74) materials. On the other hand, Trivex has a higher Abbe value and lower chromatic aberration. As the eye has an Abbe value of around 45 – 50, Trivex’ properties are perfectly matched to the eye. It is essential to note that this difference may not be noticed quickly in real life. When aspheric curvatures are used on lenses, even more thickness and weight reduction can be achieved. The difference will be less than on papers even though polycarbonate will still be more affordable than Trivex. Our A.B.O. Compared to the polycarbonate (refractive index of 1.58), Trivex has a slightly lower refractive index of 1.53. Conversely, it is more suitable for use in drill-mount frames because of its high tensile strength, which makes it resistant to cracks when drilled. Refractive Index Trivex lens material has a 1.53 index of refraction. Polycarbonate is even more popular because it is available in high quantity as a result of large scale production. If any coating is added to either polycarbonate or Trivex, the differences become more manifest, especially in terms of impact resistance. The pressure causes certain areas of the lens to become denser than others, increasing the index of refraction and causing light to … Trivex is a material that is very similar to polycarbonate and was designed to mimic poly’s impact resistance and strength while adding scratch resistance and optical clarity.
