Trivex Lenses Or High Index Lenses

Polycarbonate was the first “thinner, lighter” lens material. Polycarbonate is 10 times more impact resistant than glass and CR-39. Polycarbonate lenses are the preferred choice for safety eyeglasses and children’s eyeglasses. Each no-glare eyeglass lens is crafted utilizing the finest lens materials. The Optician offers multiple lens material options to boost visual clarity and to offer a thinner-lightweight material for higher prescriptions. Eye safety is a sensitive topic, both literally and metaphorically.
Thinner lenses are specially a considerable benefit for all those that are nearsighted , meaning they have lenses which are thinner in the center and obtain thicker at the edges. With high index lenses, these folks can now more easily fit their stronger lenses in the same stylish frames as people that have much weaker prescriptions. Also, Trivex lenses have a higher Abbe value than polycarbonate lenses.

  • Most lenses are plastic , but the least expensive plastic useful for eyeglass lenses is
  • Its impact resistance is around five times greater than other high-index choices.
  • The business then took this ultra-strong, lightweight material and applied it to consumer optical needs.
  • It incorporates tinted lenses with color correction for better contrast and glare protection.
  • Hi-Index plastic may be the thinnest, lightest weight within an eyeglass lens material The Optician offers.

At PlasticRanger, we enlighten our readers with the happenings in the world of plastics. Polycarbonate was invented in 1953 by Bayer’s Dr. Hermann Schnell and General Electric’s Dr. Daniel Fox. It had been introduced in the 1970s publicly with aerospace programs and activities. The material was used for high-end applications like helmet visitors along with space shuttle windshields; proving the material’s durability. Reviewing the totality of most of Trivex’s properties, it’s reasonable to state that Trivex lenses actually represent a bargain. Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.

Your Guide To Prescription Eyeglasses

Thinner, lighter lenses made of high index materials reflect up to 50% more light than regular glass or plastic lenses (up to 12% of available light). Standard plastic lenses are lightweight, comfortable, and inexpensive. Polycarbonate lenses certainly are a version of plastic lenses that provide impact and scratch resistance. These are the two most popular forms of glasses currently that you can buy. Trivex lenses also have an increased tensile strength than polycarbonate lenses. This is significant when it comes to mounting lenses in minimalist-design rimless frames, where small holes are drilled in the lenses to attach them to the frame.

  • You will see more clearly and be able to use many more frames with high index lenses, nevertheless, you can also hit a spot of diminishing returns.
  • Verywell Health articles are reviewed by board-certified physicians and healthcare professionals.
  • half mirror, so people can still see your eyes.
  • Polycarbonate has a certain amount of internal stress, as do many materials.
  • Mirror coatings usually do not replace tint colors, so a tint color would have to be added so as to utilize as sunglasses.

For example, this kind of lens is often utilized by fishermen who work in bright light that’s being reflected off the water. They are available mostly in grey or brown tint but many other colors are available. The anti-reflective coating decreases unwanted glare and halos at nighttime.
Rimless, three-piece frames require careful drilling and mounting of lenses. Lenses with AR coating must never by cleaned dry, as this can scratch the coating. There is absolutely no perfect way for cleaning lenses because any time you touch a lens, you could be pushing dirt against it and scratching it. We have discovered that the best method is by using a clean, micro-fiber cloth, and rub gently. You can even use soapy fingers under the sink, but be sure not to dry the lens except with a clean micro fiber cloth. Which means both materials could make the best lenses for several our needs. That said, you may still find some subtle differences between them that I will try to highlight.

Lens Materials

This is a way of measuring how likely white light is dispersed into its component colors since it passes through a lens material — an optical imperfection referred to as chromatic aberration. In fact, only polycarbonate lenses rival the protection and lightweight comfort of Trivex lenses. For the best eye protection at the job and during sports, be sure you also invest in high-quality safety frames or frames designed designed for sport eyeglasses. Polycarbonate is a thermoplastic that starts as a good material by means of small pellets. Within an eyeglass lens manufacturing process called injection molding, the polycarbonate pellets are heated until they melt.

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 so are up to 10 times more impact-resistant than plastic or glass lenses. Regular glass and plastic eyeglass lens materials can shatter upon violent contact in the same way that car safety glass does.

Our lenses are made out of advanced plastics and so are obtainable in seven indexes, which will determine how thick or thin your glasses lenses will be. People that have a stronger prescription often prefer high-index for thinner lenses, while those who are active might need impact-resistant options. Lighter than polycarbonates, built with 100% UV protection without needing a particular coating, sufficient reason for incredible durability,Trivexis what we enjoy recommending to patients.
They will have great optics, are heat resistant, and keep maintaining their dimensional stability (meaning they won’t become cloudy or warp over time). Trivex is the preferred material for some eye doctors in their own lenses. They are produced using a slower, cast molding process much like how regular plastic lenses are created.
