Titanium Glasses Frames
Titanium is a high-strength, lightweight material commonly used in everything from hubcaps to eyewear. Because titanium ranks seventh in abundance among industry elements in the earth’s crust, it is easily accessible. This material has picked up speed in the eyewear industry as a lightweight option that lends itself to unique designs and colorations.
Pros: Strong as steel, lightweight, hypoallergenic, and corrosion-resistant.
Cons: This material is more expensive than other materials. Beware of the difference between “pure titanium” and “titanium alloy.”
Stainless Steel Frames
Stainless Steel material is an alloy of iron and carbon steel with chromium and other elements. The addition of at least 10 percent chromium makes this alloy less prone to stain or rust, a factor that results in a long life compared to that of traditional steel. Because of its durability, lightweight, and sleek appearance, stainless steel has long been a choice of eyewear designers.
Pros: Non-corrosive, durable, strong, lightweight, and hypoallergenic. It can also be easily shaped into ultra-thin eyewear styles and has flexibility, which adds to the wearer’s comfort.
Cons: Not as lightweight, heat-resistant or flexible as titanium.
Nickel Titanium Frames
Nickel Titanium or NI-TI is used to manufacture Flexon™ eyewear. Ni-Ti, or titanium-based alloys, are more flexible than steel and 25 percent lighter than conventional metals.
Pros: Flexibility removes the need for spring hinge and increases comfort and durability for patients who are hard on their eyewear.
Cons: Since all Ni-Ti is nickel based, allergies and pitting may be an issue.
Monel™ Frames
Monel is a nickel alloy containing 68 percent nickel, 30 percent copper, and two percent iron. Monel,™ the most commonly used frame material today, is often used for components that require sturdiness and rigidity, such as temples and bridges.
Pros: Strong and can also be welded, brazed, and soldered.
Cons: Surface discoloration can occur from exposure to atmospheric conditions. Pitting can also occur if exposed to salt water.
Plastic Glasses Frames
Plastic materials have many style and material options. Easily colored, laminated, patterned, or even layered with fabrics, this material is one of the more creative and workable options. The two commonly used plastic frame materials are called zyl and propionate. Zyl, also known as cellulose acetate, is the most commonly used plastic frame material and is available in every color of the rainbow. Propionate is the second most common materials and is a nylon-based, hypoallergenic plastic. It’s lightweight and has a different look and feel than other plastic.
Pros: Easily molded into today’s popular wraparound styles.
Cons: Plastic frames have some drawbacks in fit. Be certain of proper fit initially since the adjustments are limited.
Gliamides and Grilamid® Eyeglass Frames
Gliamides and Grilamid is also a premier material for sports and performance frames. It is typically made of a high-quality thermoplastic material that is shock-resistant, lightweight, and non-allergenic. This material is used to manufacture Rudy Project sunglass frames. It provides structural integrity and stability that is very resistant to hot, cold, and chemical damage.
Pros: Easily molded into today’s popular wraparound styles.
Cons: Nylon frames do have some drawbacks in fit. Be certain of proper fit initially since the adjustments are limited.
Combination Eyeglass Frames
Combination frames help you get the best of both materials with frames that combine the sleek sophistication of metal with the colors and thickness of plastic. The cool contrast of these popular material duos adds visual interest.
