Eyeglass Frame Materials
Never before has there been such a variety of frame materials to use for informed, technologically-driven patients. Ask us about the features and benefits of each frame material and what best meets your lifestyle requirements.This article outlines the facts on each frame material currently used to manufacture eyeglasses available in the marketplace, to help you select the best eyeglasses for your lifestyle.
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.
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.
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.
