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. Our certified opticians will work with you to find the frame that best suits your needs and lifestyle.
Titanium
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.”
Ticral
Ticral is an alloy of titanium. It is nickel-free and thus hypoallergenic. It’s also extremely lightweight and offers many of the features of titanium without the high cost. It can be cut a bit thicker than titanium, which enables it to have the popular look of a thin plastic frame while still offering lightweight durability.
Pros
Strong, durable, and available in a variety of colors.
Cons
Not yet well known.
Stainless Steel
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.
Magnesium
Magnesium is the eighth-most abundant metal element on earth. Lighter than both titanium and aluminum, magnesium is either extracted from the ocean or recovered from minerals such as dolomite or magnetite. Because of its unique properties and high cost, it has been used in the high-end frame market.
Pros
Super-lightweight material is strong, durable, and hypoallergenic.
Cons
Costs almost 50 percent more than aluminum or steel.
Beryllium
Beryllium is six times stronger than steel and more than 30 percent lighter than aluminum. Beryllium resists corrosion and tarnish, making it an excellent choice for wearers who have high skin acidity or spend time in or around salt water. It is also the only memory metal containing no nickel and can withstand very high temperatures.
Pros
Lightweight, durable, flexible, and is available in a wide range of colors.
Cons
A very small number of people are allergic to beryllium.
PURE Aluminum
Pure Aluminum is soft enough to carve. However, mixed with small amounts of alloys, it can provide the strength of steel with only half the weight. Because it can be “sculpted,” the softer properties of aluminum break down the creative barriers present with many other strong materials.
Pros
Aesthetically pleasing, strong, lightweight, and recyclable.
Cons
Aluminum can get rigid, especially in lower temperatures. Thus, integrating elements like flex hinges into an aluminum frame can be challenging.
Nickel Titanium
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
Plastic materials have many style and material options. Easily colored, laminated, patterned, and can be layered with fabrics. The two commonly used plastic frame materials are called zyl and propionate. Zyl 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®
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. 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
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.
