Excessive external pressure placed on the lens causes light to be double or multiply refracted. They are both manufactured from different compounds and are available in a wide variety of designs and models. Creators use a mold to construct the lenses in much the same way regular plastic lenses for glasses are made. #1 Priority Should Be Optical Quality. UV Protection—Trivex offers outstanding UV protection, blocking 100 percent of UV rays all the way to 395 nanometers, well beyond ANSI standards. Polycarbonate. 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. It can be used for any activity that request your eyesight better than like: working on computer, driving or any sport. 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. The comparison of prices of polycarbonate and Trivex requires direct analysis. The scratch-resistant coating also enhances the strength of both Trivex and polycarbonate. However, it is the lightest lens material in the market and doubles up as perfect protection against UV rays. $8-$900 later I decided to educate myself on lenses and found out trivex are … Our advise will be based on your child’s prescription, frame choice, and lifestyle. It can be drilled successfully without cracking the material around drill holes. Trivex eyeglasses are more expensive as anything is new and better. We’re excited to start working with you! Trivex became the only material to pass the FDA impact resistance test as a lens material besides polycarbonate in 2001. Both polycarbonate and Trivex offer 100% protection against UV rays. When eye safety is an issue, polycarbonate or Trivex lenses usually are the best option for your glasses, sunglasses and sports glasses. Trivex is lighter than polycarbonate lenses due to lower specific gravity. @@Trivex is thinner and lighter than CR39. Hello all, I recently got new eyeglasses and prescription sunglasses at a new (to me) optometrist. If you have finished prototyping and ready to move forward to the next step. This is 40 nanometers more than untreated CR-39. This shortcoming makes it a challenge to use polycarbonate in drill-mount frames. On the other hand, Trivex has a better optical superiority with an Abbe value of 45. The best of doing this is by adding scratch-resistant materials on the surface of the lens material as a coating. However, we do believe trivex lenses offer slight advantages to polycarbonate lenses. 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. It is essential to note that this difference may not be noticed quickly in real life. It combines the positives of polycarbonate with higher optical quality, which makes it a step in the right direction for lens prescriptions. 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. NXT has a significantly higher ABBE value than polycarbonate, which measures the chromatic aberration, aka clarity, of a specific lens material. Trivex and polycarbonate both have similar impact resistance and UV protection. 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. The one who wins is you. Trivex lenses are made from a urethane-based monomer. 1. This indicate the lenses of this material for rimless glasses, if what you want. With a lower index of refraction, Trivex may be slightly thicker than polycarbonate, but is lighter, and can be surfaced to the same 1mm center thickness. The difference will be less than on papers even though polycarbonate will still be more affordable than Trivex. Trivex also has the best optical quality and is more suitable for use in drill-mount frames. Trivex Lenses. It is lighter than standard plastic lens material and features the highest impact resistance of any lens material, bar none. Here is a useful comparison of polycarbonate and Trivex: Trivex: Polycarbonate; lighter: thinner; sharper central vision; better clarity higher Abbe = less chromatic aberration = sharper peripheral vision even more impact resistant; stronger: impact resistant; chemical resistant: not chemical resistant; 100% UV protection: 100% UV protection … When carrying out a test to compare Trivex and polycarbonate, you will discover that the performance differences of the two lens materials are negligible. In terms of thickness, polycarbonate boasts of a higher refractive index of 1.58 compared to 1.53 of Trivex. This material provides clear vision, being superior to polycarbonate. trivex lenses vs polycarbonate. The pressure causes certain areas of the lens to become denser than others, increasing the index of refraction and causing light to … 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. Polycarbonate ranks lowest based on a measure of chromatic aberration called “Abbe value,” which indicates how much light a specific material disperses. Trivex lenses are lighter compared to polycarbonate lenses. Trivex and polycarbonate have been in existence for ages. This information means that Trivex lenses offer the sharpest peripheral vision. 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 vs polycarbonate: What are the Differences? Trivex lenses are made from a lightweight, impact-resistant material. » Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex.
