Trivex Index

rays. To learn more on eyeglass lenses, visit All About Vision®. But with regular plastic lenses, a lens treatment is required for these lenses to block all UV rays. This UV treatment will not change the looks of the lenses and is fairly inexpensive.

• This UV treatment will not change the appearance of the lenses and is quite inexpensive.
• Some glass can be acquired with a refractive index as high as 1.8 and 1.9.
• Even though Trivex is merely slightly thicker than polycarbonate lens materials, it’s lighter weight, superior optics, and structural qualities make it a fantastic choice for eyeglass lenses.
• In general, both materials are great for eyewear applications.
• Therefore, especially in high prescription powers, polycarbonate lenses will undoubtedly be noticeably thinner than Trivex lenses.

Various high index lenses are available today in various price points based on how much thinner they are compared to regular plastic lenses. The lenses are classified by their “index of refraction” (or “refractive index”). Originally produced by the military for helicopter windshields and fighter jet canopies, Trivex was eventually tailored for used in optical lenses. Trivex lenses are lightweight and exceptionally clear which lends itself to incredible comfort. The material can be stable, therefore the lens won’t change to look at as time passes as other materials might do. Impact Resistance—no ophthalmic-grade lens material is more impact resistant than Trivex.
Having eyewear that delivers continuous performance is vital to obtaining the most out of life—and everything begins with the lens material recommendation you make. Trivex lenses are lightweight and resist cracking, making them a great choice for rimless frames. Super Hi-Index provides a highest index of refraction out of all the Optician’s lenses to provide you with probably the most optimal vision possible. Virgin poly was not very scratch resistant, and appropriate coatings needed to be developed to ensure optical consumers would be content with their day-to-day handling of poly lenses.

Trivex Eyeglass Lenses

This is useful for all sorts of optical lenses including safety glasses and sports glasses. Hi-Index plastic is really a thinner lightweight eyeglass lens material. Glass lenses provide excellent optics, the most scratch resistant lens material and blocks UV light. However, glass lenses are heavy, thick and dangerous if broken and cannot be used in certain frame styles. Some glass is available with a refractive index as high as 1.8 and 1.9. Trivex material provides precise optical performance for every prescription. For patients with an increase of severe prescriptions or sensitivity to chromatic aberration, smaller frame styles minimize any appearance of lens thickness.
Polycarbonate lens material is the better choice for children, active adults, and activities. Polycarbonate lenses are virtually shatterproof, provide the best eye protection of any lens, and includes 100% UV protection inherently.

Lenses made out of Trivex material certainly are a great choice for anybody who leads an active life and expects clear, crisp vision correction, lightweight comfort and protection from their eyewear. POLYCARBONATElenses are thinner and lighter than regular CR-39 plastic lenses. In addition they offer 100% protection from the sun’s harmful UV light and are around 10 times more impact-resistant than plastic or glass lenses.

Driving Lenses

That means the lenses you fit on your patients have to provide just what their eyes need at any given moment. Trivex material is really a unique, scientifically-advanced category of lens material developed to provide the best balance of all performance properties – clear, light, thin and strong. If you are thinking about getting the thinnest, lightest lenses possible, there is absolutely no question that high index plastic is the best choice for you.

Low inherent material stress—Trivex lenses are not injection-molded. Today I’m likely to share the ultimate guide on Trivex vs polycarbonate.

Whats Special About Trivex?

The density varies, known as index of refraction, and the ABBE VALUES are different for the various materials. The ABBE VALUE is a number given to describe the volume of chromatic aberration of an ophthalmic lens material.
