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. 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. This article will down the facts about both Trivex and polycarbonate, put them to the test. 1 doctor agrees. This means that polycarbonate lenses are thinner than Trivex lenses. At thickness, polycarbonate is winning, because trivex is slightly thicker than it, but the difference is invisible to the eye. Further distinguishing itself, Trivex is ideal for drill mounting, as it material properties in this respect are superior to polycarbonate. Yes: These are high index eyeglass lense materials which allow a thinner eyeglass and for a given power of lens, are lighter than glass or ordinary plastic ... Read More. Other specifications like protection from direct UV rays make polycarbonate ideal for use in lenses. On the other hand, Trivex has a better optical superiority with an Abbe value of 45. The Difference: The key difference that sets the two materials apart however, insofar as providing an optimum eyewear experience, is that Trivex lenses have a higher ABBE LEVEL. 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. However, these differences are only notable on papers. It is very strong, very light, and resistant to scratches and breaking. However, Trivex has a lower refractive index and is, therefore, slightly thicker and lighter than polycarbonate. 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 can be used for any activity that request your eyesight better than like: working on computer, driving or any sport. Trivex is lighter than polycarbonate lenses due to lower specific gravity. This is because they are made up of a urethane-based monomer, which refracts less light. In fact, breaking a thin polycarbonate lens would require bending it back and forth several times. This On the other hand, a Trivex lens is marginally thicker than a polycarbonate lens in any given prescription. If you want an AR coating on the Trivex lenses you have to pay for it. Home 0.

Trivex is 90 percent more resistant to this type of induced distortion than polycarbonate. Trivex vs high index. Trivex eyeglasses are more expensive as anything is new and better. Polycarbonate. For example, Trivex did not experience any change in weight, diameter, or clarity when submerged in containers of chemicals like acetone (a volatile, flammable liquid) for 10 days. However, polycarbonate is 10% thinner than Trivex. The best of doing this is by adding scratch-resistant materials on the surface of the lens material as a coating. Posted on September 6, 2013 by adveyecarecnter. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10% lighter as a result. Both lenses have comparable impact resistance and offer 100% UVA/B protection. Trivex also has the best optical quality and is more suitable for use in drill-mount frames. Meanwhile, shatter resistance is also in favor of trivex. All rights reserved. This is 40 nanometers more than untreated CR-39. NXT lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality. When compared to other lens materials, high-index nor polycarbonate are known to provide the ultimate in optical clarity. The lower numbers are classified as mid-index lenses. It combines the positives of polycarbonate with higher optical quality, which makes it a step in the right direction for lens prescriptions. This material provides clear vision, being superior to polycarbonate. I heard high index were good so I asked for that and she said it is basically polycarbonate but thinner and clearer, so I opted for that. The flexibility of polycarbonate and Trivex means that they require protection from scratches.
