Trivex Vs Polycarbonate Vs High Index

Generally speaking, high-index is most effective for higher prescriptions. Anything above a minus 5 and above an advantage 3 is known as high-index territory. High-index materials are denser than lower-index polycarbonate, this means they bring about thinner lenses as a way to refract light accurately. However, you need to understand your choice will affect durability, visual clarity, and much more. So we’ll examine the two most typical lens materials here and present advantages and disadvantages you should be aware of.

Unlike most polycarbonate lenses, Trivex lenses are internally stress-free. Which means that such lenses have a lesser chance of breaking when under great pressure, like from thick frames. For older people, lenses with this characteristic can be extremely important. When the skin on the bridge of the nose becomes finer and much more sensitive, lightweight eyewear can decrease the likelihood of irritation. Because of the density of the high index plastic-type material it isn’t usually the lightest material even though it is thinner. Trivex alongside polycarbonate is ideal for rimless frames and the ones frames requiring drill mount screws through the lenses. Abbe value is really a measure of the lens material’s dispersion of light.
In fact, high index lenses of just one 1.60 or higher typically result in a 25% – 50% reduction in overall lens weight compared to conventional lenses. As a result of the thinner lens, you will benefit from a significantly lighter lens as well. If you want safety glasses, consult an optician who is able to tell you which frames are safety rated. Polycarbonate and Trivex lenses both block completely of the sun’s Ultra violet rays without the need for special UV-blocking lens coatings. Lenses and mounting components flex over time when you wears a rimless mounting. This can result in loose lenses and the need for replacements.

Polycarbonate Vs Trivex

Polarized lenses, photochromic lenses and most sunglass lenses. Begin by fitting every pair of glasses by measuring pantoscopic angle, vertex distance and frame wrap—whether the lens you ultimately choose actually demands these measurements.

A lens with a minimal Abbe value causes an increased dispersion and leads to unwanted chromatic aberration. Chromatic aberration is a distortion of the image because of the inability of the lens to focus all colors onto exactly the same focal point. This leads to the perception of undesirable color fringes when viewing objects for most people. Impact-resistant lenses certainly are a good

When paired with an excellent AR your patient could have a great looking and clear couple of lenses. Today, there’s many different types of lens available. Each has their pros and cons and can be recommended depending on variables like your prescription, your activity level and lifestyle, or simply personal preference. For example, the most recent Transitions technology or polarized color option will undoubtedly be a choice for polycarbonate lens material first. Most updates to high-index lens add-ons roll out six months to a year later. Actually, I believe trivex has better optics than high index.

• Finally, Trivex can undergo many surface treatments, including anti-reflective, hard coatings, and tinting.
• a strong prescription, high index lenses will be your only chance at near distortion-free vision.
• Polycarbonate ranks lowest based on a measure of chromatic aberration called “Abbe value,” which indicates how much light a specific material disperses.
• More than a decade has passed since the introduction of Trivex into the optical market.

You can find no refractive errors that make you need Trivex lenses. However, they are an excellent option for people who need safety lenses or who live active lifestyles. This is because they provide 100 percent protection from UV rays, sharper central vision, and sharper peripheral vision. High index plastic’s key feature is its thinness, especially in higher prescriptions. If you are using your glasses for indoor reading or computer work, and your prescription level isn’t too much, then plastic works fine. If you don’t want to fuss an excessive amount of about its care, a protective scratch coating is a good idea. Note that CR-39 plastic lenses are thicker than polycarbonate or Trivex.

Trivex also scores high on the durability index, is lightweight, and contains excellent UV protection capabilities. This particular characteristic is effective with rimless frames or drill mount eyewear. While other styles of lens material like polycarbonate, high-index, and glass exist, Trivex has shown to be an excellent choice for optical lenses. Polycarbonate was originally developed for fighter jet cockpits.
They are a fantastic choice for strong prescriptions, including -4.25 to -6.75 and +4.25 to +6.75. Higher-index material offers lighter and thinner glasses lenses, making them an excellent option for glasses wearers with a strong prescription. From PPG, exactly the same company that brought you Trivex, Tribrid is really a new, high-index material combining among the best attributes of its older brother.
