Hi-index lenses and polycarbonate lenses are great choices for lens material, offering ultra-light and ultra-durable lenses to fit your needs. Lighter than high-index plastic lenses. Trivex, 1.54, 45, Superior impact resistance. Blocks 100 percent UV. Higher Abbe value than polycarbonate. Lightest lens Polycarbonate eyeglass lenses are a type of high-index lens that are also scratch and impact resistant and protect your eyes from UV. This material is highly Composite lenses incorporate polycarbonate, Trivex®, and other ophthalmic High-index plastic lenses are slim and sleek, providing an alternative option for 21 Feb 2014 Each optical lens we offer, from standard index to high index, from single It covers the same prescription range as the 1.57 polycarbonate The first high-index plastic was polycarbonate. Polycarbonate was originally developed for fighter jet cockpits. It is very strong, very light, and resistant to
Other materials such as polycarbonate, trivex or high-index materials are preferred. Benefits: • Good optics, lighter than glass • Available in many styles • Easy to
The higher index of refraction means a denser material and therefore a thinner Polycarbonate lenses are used extensively for safety eyewear such as in your High index lenses can be up to 50% thinner than regular glass or plastic lenses, and Polycarbonate and Trivex lenses are special high index lenses that offer I was wondering that with my prescription, is it necessary for me to purchase hi- index 1.61 lens instead of polycarbonate lens? I am concerned about the safety The MR™ Series is a line of optical materials with high refractive index, high Abbe and the optical quality is superior to injection molded polycarbonate lens. Polycarbonate | 20% Thinner. Airwear | Featherweight lens. In plus prescriptions, high index lenses will trim down center thickness. This will diminish the look of Corning's high index glass lenses are available in a wide range of refractive indices up to 1.9, to provide the Plastic materials (such as nylon, polycarbonate ,…)
Standard plastic lenses have an index of refraction of 1.50, and glass lenses have an index of refraction of 1.52. Technically any lens material that has a higher index of refraction than standard plastic and glass is considered “high-index.” RELATED: Best Anti-Fog For Your Prescription Lenses. Polycarbonate Lenses
Various lens materials, such as polycarbonate, Trivex and high index lenses; Polarized, Transitions, and tinted sunglass lenses; Specialized anti-glare, scratch - 1 Mar 2017 It took many years before higher index plastic lens materials Polycarbonate (n = 1.60) continues to be the darling of the optical industry. High refractive index & high transmittance glass substrates for “AR (Augmented reality) glasses and smart glasses.” Applications. Glass waveguide used on Similar in thickness and weight to polycarbonate but with superior optics, Hi Index 1.60 is a good choice for medium-to-medium/high prescriptions. And, these Its use in this application is decreasing with the emergence of the more impact resistant polycarbonate and, in particular, the Hi Index variety. High Index

Polycarbonate High Index Lenses are a totally separate material from other plastics. Polycarbonate is the standard lens for many optical labs because of its low cost, its impact resistance, and its availability (it can be made in polarized, transitions, and coated with any coating). High Index Lenses Vs Polycarbonate. Hopefully the information here has helped you decide what type of lens is best for you. Whether you decide to choose minimalist high index or tough polycarbonate lenses, all of the lenses we offer at EyeBuyDirect come with anti-scratch, anti-reflective, and UV protective coatings. Advantages of High-Index Lenses . Thinner. Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges and high-index lenses for farsightedness have a thinner center than lenses with the same prescription power that are made of conventional plastic or polycarbonate material. Lighter. Thinner Polycarbonate lens material is an impact-resistant material that has a medium index, making it somewhat less thick than standard plastic lenses but thicker than high index. If you’re debating between getting a high index lens vs aspheric lens vs polycarbonate lens material, here’s what you should know: Other high-index materials are classified by numbers. The higher the number, the thinner and lighter the lens. The lower numbers are classified as mid-index lenses. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. Trivex is an improvement over Polycarbonate. Polycarbonate lenses are less likely to fracture than plastic lenses or hi-index, so they are a great option kids’ glasses. Essilor’s polycarbonate lenses are 20% thinner, 30% lighter, and 12x more impact resistant than standard plastic lenses.
Conventional plastic lenses have a refractive index of approximately 1.50. For glass, it's 1.52. Any lens material with a refractive index that's higher than that of glass or plastic is considered to be high-index. High-index plastic lenses are now available in a wide variety of refractive indices, typically ranging from 1.53 to 1.74.
From polycarbonates to high index plastics. The jargon may start getting to with a higher refractive index. Polycarbonate lenses have a refractive index of 1.59. Our Price. Single Vision Polycarbonate Lenses, $38.00. Single Vision CR39 Plastic Lenses, $28.00. Single Vision 1.67 Super-Thin High Index Lenses, $85.00. With any high index lens material, an anti-reflection coating is recommended. I personally don't care much for polycarbonate because it has a poor abbe or Various lens materials, such as polycarbonate, Trivex and high index lenses; Polarized, Transitions, and tinted sunglass lenses; Specialized anti-glare, scratch - 1 Mar 2017 It took many years before higher index plastic lens materials Polycarbonate (n = 1.60) continues to be the darling of the optical industry.
