Frame Materials

The options for spectacle frames are never-ending, reflecting the personal style of the wearer and holding the lenses in place. Frame materials also vary depending on the prescription of the lens and each individual’s needs and lifestyle with new innovative engineering creating different options every year.

Frame materials for eyeglasses are classified under -
• Plastic
• Metal
• Bio degradables

Plastics

Acetate/Zyl

The most used material when it comes to quality designer frames is definitely acetate. A high-quality plastic originating from the renewable resources of wood pulp and natural cotton fibers. Acetate retains its color brightness impeccably over time because its hue is embedded in the material.
 

Nylon

This frame material is mostly used in less expensive sunglasses. Nylon is strong, lightweight and flexible, however it can become brittle with usage. For this reason, it has for the most part been replaced by nylon blends – polyamides, co polyamides and gliamides – which are more durable.
 

TR90 Nylon

TR90 is thermoplastic material that is incredibly durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable because they have a flexible quality. Since they are flexible, they can bend under pressure and contour your face comfortably. This flexibility also makes TR90 glasses resilient to damage.
 

Ultem

ULTEM resin is a flame-retardant, high-performance thermoplastic. It features a high strength-to-weight ratio, excellent heat resistance, and high impact strength. This material is ultra-lightweight, durable, and heat resistant up to 400⁰. Ultem frames can weigh only 1/3 of the weight of traditional plastic or metal frames.

Metal

Titanium

One of the most important aspects of keeping an eyeglasses frame is its durability. No matter how carefully you use your eyewear frames, they are bound to break or fall. Titanium material can be bent and twisted and then come back to its original form. The quality of these frames is durable and reliable for rough use also. As compared with regular metal, Titanium is one of the lightest and most preferred materials used in the manufacturing of eyeglasses frames. These Titanium frames can be easily worn with a lot of comfort and relief while playing games, jogging or running. With no maintenance required for these frames, it is surely one of the best materials especially for eyeglass frames.
 

Flexon or Memory Metal

This is a titanium alloy composed of roughly 50% Titanium and 50% Nickel. Frames made of memory metal are extremely flexible and can be twisted or bent to an extreme and still return to their original shape. This feature makes memory metal frames great for kids or anyone who is rough with their glasses.
 

Beta Titanium

Alloy of predominantly Titanium, with small amounts of Aluminum and Vanadium. The other metals in the alloy make beta titanium more flexible than 100% titanium for easier fitting adjustments. Beta Titanium has memory features and is mostly used in high-quality designer frames. Due to its toughness and low weight, it can be used to create thick looking frame fronts as well as ultra-thin eyewear temples.
 

Stainless Steel

Stainless Steel frames are an alternative to Titanium. Qualities of stainless steel frames include lightweight, low toxicity and strength and many stainless steel frames also are Nickel-free and thus hypoallergenic. Stainless Steel is readily available and reasonably priced. It’s an alloy of Steel and Chromium, which provides excellent resistance to corrosion, abrasion, and heat.
 

Aluminum

The most abundant metal in the earth’s crust, Aluminum is a lightweight option for eyeglass frames. It is the most widely used non-ferrous metal in the world. In addition to its lightweight, Aluminum is also highly corrosion-resistant, soft, and durable. Aluminum is also 100 percent recyclable and can bend which can make it slightly less durable than other materials.
 

Gold

Dense and shiny, Gold is the most malleable metal on the planet. Because of its high cost, it is used sparingly in the manufacture of eyeglass frames. Worked into stunning silhouettes in some high-end eyewear collections, it is also used in more moderately-priced lines as an accent or plating.
