What is Essilor Trivex?
Essilor Trivex SV Lenses Trivex takes tint better than polycarbonate lenses, and has a higher ABBE value, leading to better clarity and less distortion than polycarbonate lenses. Essilor is the leading lens maker in the world, and all of the Essilor lenses we sell are made in a U.S. laboratory.
What lens has the highest Abbe value?
However, Trivex lenses have a much higher abbe value (43-45) vs. polycarbonate (abbe value 30) making it much better in optical clarity with fewer chromatic aberrations. Trivex also has a slightly lower density so it is lighter than polycarbonate. In fact, Trivex is the lightest weight lens material available.
What is the index of Trivex lenses?
The index of Trivex is 1.530. Steeper curves would be needed to make an Rx in Trivex than in polycarbonate. The higher the lens power, the more difference there will be in curves and thickness. Abbe Value The Abbe number, or V-value, is a measurement of the dispersive properties of a material.
Is Trivex better than high index?
Trivex has a low index of 1.53, similar to standard plastic. Trivex is more impact resistant than high index plastic, making it a much better choice for safety glasses or other types of glasses that need to meet certain impact requirements.
Are Trivex lenses worth it?
Trivex lenses tend to cost more than polycarbonate or standard plastic lenses. But if you want what many eye care professionals consider to be the best combination of safety, comfort, appearance and optical performance for most eyeglass prescriptions, the Trivex price tag may be an investment worth making.
Are Trivex lenses the best?
When eye safety is a concern, lenses made of polycarbonate or Trivex are the best choice for your eyeglasses, sunglasses and sports eyewear. These lenses are significantly more impact-resistant than other lenses and: Are lighter and thinner than regular plastic lenses.
What are the thinnest lenses for high prescription glasses?
What are the Thinnest Lenses for High Prescription Glasses? 1.74 index lenses are the thinnest lenses for high prescriptions available. These ultra-light, ultra-sleek lenses are the thinnest kind developed yet, and accommodate the highest prescriptions possible.
Which is better polycarbonate or Trivex?
Thickness: Polycarbonate lenses have a higher index of refraction than Trivex lenses, but not by much (1.58 vs 1.53). Trivex lenses have a higher Abbe value so they can produce both sharper central and peripheral vision with less chromatic aberration than polycarbonate lenses.
Should I get Trivex or high index lenses?
Buy High Index Lenses High index plastic has similar scratch resistance to Trivex. Trivex is more impact resistant than high index plastic, making it a much better choice for safety glasses or other types of glasses that need to meet certain impact requirements. Trivex is generally a similar cost to high index plastic.
Is Trivex worth the extra cost?
Why are Essilor lenses made out of Airwear?
Safer – Airwear lenses are 12x stronger than standard plastic lenses, making them virtually unbreakable. Airwear lenses are so tough and durable that NASA uses the same material to construct visors for astronauts. u000bGreen – Airwear lenses are the first Essilor material to go green.
What is the Abbe value of Trivex lenses?
Trivex has an abbe value of 43–45, while standard polycarbonate has an abbe value of 30. Additionally, Trivex’s light transmittance is 91.4 percent, directly affecting the clarity, brightness, and crispness of your vision when wearing this lens material. This is the highest level of all lens materials for glasses.
What was the original use of Trivex material?
Trivex was originally developed for military use by PPG Industries in 2001. The company then took this ultra-strong, lightweight material and applied it to consumer optical needs. The material is a urethane-based pre-polymer, named after the three important properties of this material:
Which is the material with the lowest Abbe number?
Note that crown glass has the highest ABBE number (least aberration) and polycarbonate has the lowest ABBE number (most aberration). The higher index of refraction means a denser material and therefore a thinner lens.
