Trivex Glasses

This makes it a good choice for rimless glasses, because drilling holes in to the lenses won’t create hairline cracks like with polycarbonate.

They are produced utilizing a slower, cast molding process similar to how regular plastic lenses are created. This gives Trivex lenses the advantage of sharper optics than injection-molded polycarbonate lenses, according to PPG. Polycarbonate originated in the 1970s for aerospace applications. It is useful for the helmet visors of astronauts and for space shuttle windshields. Polycarbonate was adapted for used in eyeglass lenses in reaction to demand for lightweight, impact-resistant lenses. Specific gravity is the weight in grams of one cubic centimeter of the material.
Trivex was originally developed for the military, as visual armor. PPG Industries took the technology and adapted it for the optical industry. PPG named the material Trivex due to its three main performance properties. The three main properties are superior optics, ultra-lightweight, and extreme strength.
Many of these fine brands of discount eyeglasses includeJ.F. Stay on the surface of the latest news about prescription safety glasses, eyewear, sunglasses, and all the trends in the market. Essilor is the largest and finest quality eyeglass lens maker on the globe, with over 200 lens labs in the usa alone. When you ask Eyeglasses.com to create your lenses, you aren’t obtaining a local guy cutting lenses in the trunk room on aged equipment. You are getting the most effective plastic lens, installed in an excellent controlled, ISO 9000 lens-making laboratory. Your lenses pass through quality control stations before they’re finally released. If the lenses fail at any among those stations, they’re returned for further processing, or they are scrapped and begun again.

Bright Opticals

However, clear vision with several safety features is important to numerous glasses wearers. So some people opt to spend of pocket for Trivex lenses.

• It’s that point of year whenever we start thinking about back again to school and children’s eyewear.
• This material differs from traditional polycarbonate in what makes it strong.
• At Eyeglasses.com, we only use labs that hire a large staff of highly trained technicians, performing a large level of lenses every day.
• Trivex lenses are a fantastic choice if safety can be an issue or you lead a dynamic lifestyle.
• Lenses made out of Trivex material certainly are a great choice for anybody who leads an active life and expects clear, crisp vision, lightweight comfort and the best in protection from their eyewear.

Between coatings and type of eyewear, Trivex lenses can become expensive. Finally, Trivex can undergo many surface treatments, including anti-reflective, hard coatings, and tinting. This aspect makes Trivex a fantastic option for sunglasses, too. While other styles of lens material like polycarbonate, high-index, and glass exist, Trivex has shown to be an excellent choice for optical lenses.

What Are Trivex Spectacle Lenses?

All REKS frames are finished with this Satin Touch® rubberized coating that provides extraordinary comfort. THE ACTIVITY lens groove has been designed to accept prescription lenses. The next time you’re in the market for a set of safety glasses, contemplate using Trivex as a lighter, higher-clarity option to polycarbonate. For reading, computer work, driving, and any moment vision acuity is important, Trivex material provides the optical quality that optimizes corrective prescriptions and helps to reduce eye strain. Or, you can submit frames for replacement prescription lenses (we call that “replacement lenses”). [newline]Replacement glasses lenses are perfect for online mail order. Trivex lenses are slightly lighter, have an increased tensile strength, and may produce sharper central vision and peripheral vision due to their higher Abbe value and lower internal stress.
When lenses are made from materials with a lesser Abbe value, a particular deviation depending is expected. Trivex lenses will certainly offer better clarity and visual experience than polycarbonate lenses, thanks to their high ABBE value. Just like polycarbonate, Trivex had not been originally developed to be utilized in eyewear. It was developed keeping in mind the necessity for durable military jet windshields along with other similar military applications. In the year 2002, PPG industries developed a chemical process with material to be specifically used for eye lenses. Trivex also scores very high on the durability index, is lightweight, and has excellent UV protection capabilities. Shop and purchase Trivex Lenses online at Go-Optic.com and enjoy enough time and money you save.

The refractive index of the lens is 1.53 which is concidered a Normal Index lens. They might be for Distance, intermediate , or items up close . Extra Durable lenses have a higher tensil strength and come with a scratch resistant hard coating. Trivex offers similar scratch and impact resistance to Polycarbonate but is closer in optical quality to CR-39.

Comfort

The higher the number, the more dense, or heavy, a lens material is. Trivex gets the lowest specific gravity of any commonly used lens material. Trivex is 16% lighter than CR-39, 25% lighter than 1.66, and 8% lighter than polycarbonate! It can also be surfaced right down to a center thickness of 1 1.0mm.
The laboratories that we use each have many years of experience and do thousands of lenses each week. Each lab that we use inspects each lens many times during the manufacturing process. When we have the finished product from the lab, we do our very own final inspection. Anti-scratch or anti-reflective coatings can raise costs as well. Fortunately, because Trivex has inherent UV protection, there is no need to pay for a UV coating.
