How strong is Trivex?

Lens Material or Lens Index – The lens index refers to the “index of refraction,” or just how much the lens

Trivex lenses are a relatively new development in the lens world. Trivex lenses have a 1.53 index which makes them a little thinner than regular plastic lenses, and a little thicker than polycarbonate lenses. The Trivex lens material is lighter than polycarbonate, and also has better visual acuity than polycarbonate, and is also recommended as a safety material much like polycarbonate. Polycarbonate lenses are made from a kind of plastic that’s more impact-resistant than standard plastic lenses. Polycarbonate lenses may also be much thinner tvand lighter in weight.
As the eye comes with an Abbe value of around 45 – 50, Trivex’ properties are perfectly matched to the eye. Therefore annoying chromatic aberrations certainly are a thing of the past. Further distinguishing itself, Trivex is fantastic for drill mounting, since it material properties in this respect are more advanced than polycarbonate.

Choose A Lens Type Based On Your Lifestyle

Tiny pellets of this thermoplastic material are melted down and injected into a high-pressure mold to create polycarbonate lenses. An unfortunate byproduct of the production method is the insufficient uniformity of the material throughout the lens as a result of injection points. This makes eyeglasses with Trivex lenses exceptionally comfortable to wear and reduces the risk of one’s glasses sliding down the bridge of one’s nose. This flexibility also means polycarbonate and Trivex lenses need a scratch-resistant coating to prevent surface scratches. Today’s modern scratch-resistant coatings could make the surface of polycarbonate and Trivex lenses nearly as hard as glass. The cost of polycarbonate and Trivex lenses may differ considerably, but many optical stores charge more for Trivex lenses than polycarbonate lenses. Unlike most polycarbonate lenses, Trivex lenses are internally stress-free.
In 2001, PPG Industries created a new purpose for a breakthrough plastic technology called Trivex. This urethane-based pre-polymer substance has three primary benefits for eyeglass lenses. A competitor to Polycarbonate is making strong inroads in to the market. Like polycarbonate, Trivex is known as a mid-index material and has inherent UV protection. It’s suprisingly low specific gravity, however, makes it as lightweight as many high index materials for less cost. They’re recommended for strong prescriptions greater than +5 or -5, and for those who

• Specific gravity is the weight in grams of 1 cubic centimeter of the material.
• They may scratch and also shatter easier than their other counterparts but there are usually anti-scratch coatings which may be added if necessary.
• Between coatings and type of eyewear, Trivex lenses can become expensive.

Trivex is one of the latest materials for prescription eyeglasses, also it provides an innovative option for children or even more active adults. Despite its benefits, you certainly do not need to join this material because it is new.

Prescription Lenses

High index lenses provide a thinner lens but usually have lower abbe values. The Abbe value determines to a large part the optical integrity of the lens. Start protecting your eyes with some of the best eyeglass lenses today. Flexible spending accounts , health savings accounts , and out-of-network vision insurance plan can all be utilized towards awesome new prescription sunglasses, eyeglasses, and goggles.
It is not dependant on your doctor, although a health care provider can help you make your decision. For example, if you need your glasses only for distance vision, or only for reading, then single vision lenses will be the best choice. For the fashion-conscious, lenses that provide optical quality, lightweight comfort, strength and protection are always however you like! Trivexmaterial is really a perfect fit for several frame designs, in fact it is especially well-suited for rimless (drill-mount) and semi-rimless styles. Though these lenses are especially beneficial for those who have a strong eyeglasses prescription, they can create a noticeable difference in the appearance of virtually any pair of glasses. High index lenses bend light more efficiently than regular glass or plastic lenses, so less lens material is required to correct your vision.

For children’s eyewear, choose a sturdy frame and lightweight polycarbonate or Trivex lenses. High-index lenses are eyeglass lenses that are designed to be thinner and lighter than regular lenses. They are generally recommended for those who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness, or astigmatism. The sort of prescription eyeglass lenses you choose is determined by your life style and your needs.

More often than not, your prescription will determine the very best lens material to utilize. In general, a higher index lens will undoubtedly be thinner, but Only when you’ve got a high enough prescription. If your prescription is under +/-3.00, then spending more money on an increased index lens will not help you. Conversely, the thinnest lenses for a higher prescription would be the higher index lenses. For us to create progressive lenses in new frames, we might ask you for a segment height measurement. For replacement lenses, we are able to read the segment height from the lenses so you don’t need to send it to us.
