Find your distributor today!. The CR-39 lens had several drawbacks, including a low refractive index, being thick and cosmetically unattractive. Lenses made from PPG CR-39 monomer are scratch- resistant, lightweight, have less chromatic aberration than polycarbonate lenses, and stand up to heat and household chemicals and cleaning products. Dec 31, 2020 · Acrylic lenses, whose technical name is polymethacrylate, has become customary in most ready-made reading glasses. Learn when standard plastic lenses are ideal, when to upgrade to high-index or polycarbonate, and how coatings affect performance. 49) and the Abbe value (58) are the same for both acrylic and CR-39 so in itself as a plastic material you might think that they should offer the same clarity. CR-39 is a type of plastic material used in various applications, including eyeglasses, lenses, and other optical components. It is a thermoset resin, meaning it is formed through a chemical reaction and cannot be melted or reformed once it has been created. The benefits are clear. CR-39 (HOMALITE H-911) CR-39 optical grade acrylic sheet is available through the Professional Plastics website. Here, we break down the properties of these Our proprietary PPG CR-39 allyl-diglycol-carbonate (ADC) monomer combines the optics of glass with the durability of a thermoset material. Aug 19, 2018 · Benefits of CR-39 Plastic Lenses Glass lenses were the sole lens material before CR-39 plastic lenses entered the fold in 1947. Dec 6, 2025 · Explore why CR-39 remains the benchmark for optical clarity in standard plastic lenses, detailing its history, properties, and modern context. It was discovered by chemists from Columbia Company in the United States in the 1940s. May 28, 2024 · In this guide, we’ll explore the most common eyeglass lens materials: CR-39®, polycarbonate, high-index plastic, Trivex®, and glass. The index of refraction (1. May 24, 2014 · This article talks about what is CR39 lens. optical lens material The term CR-39 technically refers to the ADC monomer, but is more commonly used to refer to the finished plastic.
