MATERIAL WORLD

To achieve optimal eyewear performance, your frame material choice can be just as important as the lens material you select.

With so many generic and proprietary frame materials available, it can be difficult to keep up with what’s out there and the features and benefits of each. A little background can go a long way in understanding and working with frame materials, so consider the following wide selection of both generic frame materials as well as special frame materials offered by specific frame companies, some of which are proprietary and some of which are available from a number of companies but branded differently by each manufacturer.

As you can see from this special section on frame materials, eyewear frames are made primarily of metals and/or plastics, but there are a wide variety of materials within each category.

METALS
Titanium and beta titanium are handled similarly. Strong, light and corrosion resistant, titanium is recommended for patients who may have allergic reactions to other metals. Because it is more difficult to bend than other metals, it is always best to edge the lenses to fit the frame precisely. Memory metals combine titanium and nickel into a metal that returns to its original shape. While they cannot be adjusted, these frames feature adjustable endpieces, eyewires, temple tips and nosepad arms. A little easier to work with, beryllium offers the corrosion resistance of titanium. Stainless steel is also durable but tends to be a bit heavier.

PLASTICS
Most plastic frames are cellulose acetate, often called zyl. Lightweight, adjustable and inexpensive, zyl comes in many grades, and better quality zyl frames are made with durable, flexible Mazzucchelli acetate, which holds its color longer. Proprianate is a nylon-based plastic that is lightweight, hypoallergenic and often used in sports frames. Nylon is lightweight and flexible but difficult to adjust or insert lenses into, so it is often used as a blended material in frames.

NEW MATERIALS IN CCOLE HAAN GRAND.ØS COLLECTION FROM ALTAIR

OPTYL FROM SAFILO FITS THE FACE AND ETURNS TO ITS ORIGINAL SHAPE
An epoxy resin that has been available for decades, Safilo’s proprietary Optyl is strong, lightweight, flexible and comfortable with shape memory. Optyl can be heated to fit the anatomy of a face, and the new form is maintained when it cools. When heated to the “memory” temperature again, it returns to its original shape. It features hypoallergenic properties and is resistant to perspiration and cosmetics, making it appropriate for even the most sensitive skin.

TIMBERLAND FROM MARCOLIN EARNS THE EARTHKEEPERS MARK WITH BIO-BASED FRAMES
Instead of using petroleum-based materials, Timberland products earning the Earthkeepers mark are constructed of bio-based injected frames. The bio-based material comes from the seed of a castor plant, a durable, fast-growing perennial that can withstand droughts and harsh conditions. The castor plant’s seed pods are harvested, and castor oil is extracted to produce a natural substance known as bio-based plastic. Durable and lightweight, these frames can endure harsh conditions to maintain their comfortable shape

HYPOALLERGENIC SPX FROM SILHOUETTE OFFERS UNLIMITED SHAPE AND DESIGN POSSIBILITIES
SPX, a high-tech polymer only produced by Silhouette, is known for its flexibility and stability. Considered hypoallergenic, it doesn’t react with body chemicals or cosmetics. It is also UV resistant. Manufactured by Silhouette Optical and used in an injection-molding process, SPX offers many surface finish and color options that are not only extremely durable but also comfortable. Most recently, Silhouette’s new Essence Collection combines SPX with titanium to create light yet resilient frames.

SDN-6 HYPOALLERGENIC MEMORYPLASTIC IN CLEARVISION’S ASPIRE
Thin and light, Aspire Eyewear has evolved since its introduction in 2015 by ClearVision. The latest iteration, Aspire 4.0 is crafted in innovative SDN-6 hypoallergenic memory plastic that offers a ‘barely-there’ feel and fit. The proprietary SDN-6 material offers shape memory and heat resistance, and it will not fade from UV exposure. Using a proprietary manufacturing process allows for a comfortable built-up saddle bridge that removes the need for adjustable metal pad arms with nosepads, creating frames that fit like typical acetate frames.TR-90 and stainless steel temple materials enhance the frames’ look and ultra lightweight feel. An Aspire frame is almost 50% lighter and almost 50% thinner than a typical acetate frame and uses screwless hinge technology for a streamlined, easy-to-use endpiece attachment system.

COSTA’S UNTANGLED COLLECTION RECYCLES DISCARDED PLASTIC FISHING NETS
In keeping with Costa’s commitment to protecting the world’s oceans and waterways, the Untangled Collection is made by recycling discarded plastic fishing nets. By joining forces with Bureo, which works with fishing communities to turn discarded fishing nets into all kinds of products, the company transforms nylon pellets recycled from fishing nets into Costa sunglasses. Not only is Costa’s Untangled Collection made of recycled materials, but it is also recyclable. Customers will be able to return their sunglasses via PLUSFoam (which provided recyclable rubber for the nosepads and temple tips of the collection) to be recycled at the end of the product’s life.

PLANT-BASED Z-RESIN FROM ZEAL OPTICS REDUCES THE MANUFACTURING CARBON FOOTPRINT
Zeal Optics frames (and Ellume polarized lenses) are made from Z-Resin, a plant-based material derived from the castor plant, a fast-growing perennial that is easy to plant, withstands drought and thrives on marginal lands. Using this material rather than petroleum-based products reduces the amount of carbon dioxide produced during manufacturing while also contributing to a lighter finished weight.
