What is Trivex impact resistant lens?
Trivex lenses Trivex is another lightweight, impact-resistant material for eyeglass lenses. Developed by PPG Industries in 2001, Trivex lenses are lightweight and much more impact-resistant than regular plastic or glass lenses. Trivex lenses are made of a urethane-based monomer.
What is Trivex material?
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. The index of Trivex is 1.530. Steeper curves would be needed to make an Rx in Trivex than in polycarbonate.
Which lens material is the most impact resistant?
Polycarbonate
Polycarbonate: Polycarbonate is the lens choice for maximum impact resistance. With the designation of High Impact, they are 10 times more impact resistant than conventional plastic or glass lenses.
Is Trivex impact resistant?
When it comes to eye safety, polycarbonate and Trivex lenses should be the first options you consider. Not only are they thinner and lighter than other lens materials, but they are 10 times more impact-resistant than ordinary plastic or glass lenses. They also provide 100\% protection from UV rays.
What is an aspheric lens in glasses?
Aspheric lenses improve the cosmetics of a pair of glasses by using surface curves that are flatter centrally and progressively flattened (in plus prescriptions) as one moves from lens center to edge.
What is Phoenix lens material?
Phoenix is a proprietary (Trivex-based) material developed exclusively for HOYA. It provides mechanical strength and robustness to the lens without compromise to optical quality.
What is the difference between Trivex and polycarbonate lenses?
Thickness: Polycarbonate lenses have a higher index of refraction than Trivex lenses, but not by much (1.58 vs 1.53). This translates to a lens that is around 10\% thinner. Trivex lenses are composed of a urethane-based monomer that has lower specific gravity than polycarbonate and is 10\% lighter as a result.
What material are glasses lenses made of?
There are four main types of plastics used to make eyeglass and sunglass lenses: plastic, Trivex, polycarbonate, and high-index plastics.
What is impact resistant?
Impact resistance is a material’s ability to withstand intense force or shock applied to it over a short period of time. Impact resistance is an important consideration for fall protection equipment.
Are polycarbonate and Trivex lenses impact resistant?
Polycarbonate and Trivex lenses are much more impact-resistant than regular glass and plastic lenses (including other high-index lenses) because these lightweight lens materials are relatively “soft” — which means they can absorb energy without lens fracturing.
What are Trivex lenses made from?
Trivex lenses are made from a lightweight, impact-resistant material. It was developed in 2001 by PPG Industries as an alternative to polycarbonate. Trivex lenses are made from a urethane-based monomer.
What is the difference between polycarbonate and Trivex?
In 2001, PPG Industries (Pittsburgh, Penn.) introduced a rival lens material called Trivex. Like polycarbonate lenses, lenses made of Trivex are thin, lightweight and much more impact-resistant than regular plastic or glass lenses.
What are the benefits of using targettrivex lenses over other lenses?
Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses. Impact resistance.
