What is Trivex SV?
Trivex is a new material that is a stronger, more resistant, clearer alternative to standard polycarbonate, which is one of the best materials for prescription glasses on the market Not only is Trivex strong and lightweight, it also offers 100 percent protection from UVA and UVB rays, sharper central vision, and …
Are Trivex lenses worth it?
Trivex lenses tend to cost more than polycarbonate or standard plastic lenses. But if you want what many eye care professionals consider to be the best combination of safety, comfort, appearance and optical performance for most eyeglass prescriptions, the Trivex price tag may be an investment worth making.
Which is better polycarbonate or Trivex?
Trivex lenses have a higher Abbe value so they can produce both sharper central and peripheral vision with less chromatic aberration than polycarbonate lenses. Basically, your vision will be clearer and contain fewer distortions with Trivex lenses.
What does SV mean for eyeglasses?
Single vision lenses are a type of glasses lens that correct vision for a single distance. That means, in general, that they work for people that are nearsightedness or farsightedness, but not for those who are both.
What are zenni lenses made of?
All Zenni high-index lenses are made with MR™, a premium lens material. MR™ is a trademark of Mitsui Chemicals in Japan, a global leading provider of ophthalmic lens materials and technologies.
Are high-index lenses better than polycarbonate?
Polycarbonate is by far the safest lens available. It’s up to 10X more impact-resistant than high-index lenses and is therefore the ideal lens material for sports protective eyewear and children’s glasses. Polycarbonate is the standard choice for almost all eyewear that requires shatter and/or chip resistance.
What is the clearest eyeglass lens?
Trivex lens materials have a Abbe Value of 45, which is higher than polycarbonate and all high index plastic lens material. It provides an almost ideal blend of qualities for optimal vision results and is lighter in weight than polycarbonate lenses of equal size.
Who makes Trivex lenses?
PPG Industries
PPG Industries adapted the technology for the optical industry. Trivex is a urethane-based pre-polymer. PPG named the material Trivex because of its three main properties which are good optics, light weight, and strength.
What are SV poly lenses?
Polycarbonate lenses are thinner and lighter than standard plastic, have increased impact resistance and 100% UV protection. The high impact resistance makes polycarbonate the perfect choice for kids and sports enthusiasts.
What is SV Poly in glasses?
Clear Polycarbonate: Also called as Poly, this is a high-index material that is tough, shatter-resistant, lightweight, thin and safe for active wearers, home and on-the-job safety, and everyday wear. Polycarbonate was the first plastic high index lens and still has one of the highest index ratings (1.59).
What is a Trivex lens?
Trivex is a urethane-based pre-polymer substance developed by PPG Industries for use in eyeglasses. It was designed to provide exceptional optical clarity, high-performance strength, and ultra-lightweight comfort. Do I need Trivex lenses? There are no refractive errors that make you NEED Trivex lenses.
What is Trivex’s light transmittance?
Additionally, Trivex’s light transmittance is 91.4 percent, directly affecting the clarity, brightness, and crispness of your vision when wearing this lens material. This is the highest level of all lens materials for glasses.
What are the benefits of Trivex?
With aspheric and atoric lens designs (flatter lens curves), Trivex enhances comfort because it has a slimmer profile. Scratch protection. Those who want to avoid scratches on their eyewear can ask for an anti-scratch coating on this type of plastic material. Optical clarity. Trivex has a high Abbe value that offers clean, sharp vision.
Does Trivex have a lower specific gravity than polycarbonate?
Lastly, Trivex has a lower specific gravity (1.11) to that of polycarbonate (1.66). Specific gravity describes the ratio of density of any given material to that of a reference substance.
