There are no scratches, Q: 1. 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. Trivex is a great alternative to polycarbonate lenses. Polycarbonate also has a high likelihood of cracking when drilled because it has a low tensile strength. Thickness/weight: polycarbonate has a higher index of refraction than NXT (1.58 vs. 1.53) and a lower specific gravity than polycarbonate. It combines the positives of polycarbonate with higher optical quality, which makes it a step in the right direction for lens prescriptions. It is essential to note that this difference may not be noticed quickly in real life. That is because Trivex has a lower specific gravity compared to polycarbonate. A 36-year-old member asked: are polycarbonate lenses helpful? Trivex is extremely shatter resistant, chemical resistant. I have. This difference is, however, subjective. The comparison is based on the features of Trivex and polycarbonate. In terms of thickness, polycarbonate boasts of a higher refractive index of 1.58 compared to 1.53 of Trivex. Both polycarbonate and Trivex offer 100% protection against UV rays. As the eye has an Abbe value of around 45 – 50, Trivex’ properties are perfectly matched to the eye. If any coating is added to either polycarbonate or Trivex, the differences become more manifest, especially in terms of impact resistance. This feature is impacted by a higher refraction index and lower specific gravity. However, these materials are often soft (can absorb energy without cracking. NXT lenses can be most closely compared to glass or mineral lenses when it comes to offering superior optical quality. Most sports lenses are made of 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. 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.

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. 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. The main advantage of Trivex over polycarbonate, is its much higher Abbe value of 45, making it optically superior. However, polycarbonate is 10% thinner than Trivex. Trivex is also much more resistant to chemicals than polycarbonate. The higher the number, the thinner and lighter the lens. » You will find out that the two lens materials are used in different ways and for different purposes. Hello all, I recently got new eyeglasses and prescription sunglasses at a new (to me) optometrist. 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. High index plastic’s key feature is its thinness, especially in higher prescriptions. Other high-index materials are classified by numbers. If you want an AR coating on the Trivex lenses you have to pay for it. The difference will be less than on papers even though polycarbonate will still be more affordable than Trivex. As noted above, both polycarbonate and Trivex have similar impact resistance, which is also higher than other forms of plastic. acetone) while polycarbonate eyeglass lens is not. Polycarbonate has a good amount of flexibility. Also, polycarbonate can be used in this way but is less resistant and sometimes break around the drill holes at mounting.
