Choosing eyeglasses with the qualities that are most significant to you may be a matter of selecting a frame material, each distinguished by its own strengths.
You may also select frames depending on things like color, hypoallergenic materials, toughness, lightness, cost, and uniqueness.
Metallic is the most widely used materials for eyeglass frames. There are many kinds of metal to choose from, with each having its own distinctive attributes.
Titanium. This quality metal is extremely tough, durable and corrosion-resistant. It’s also 40% lighter than some other metals, along with hypoallergenic, making it a nearly ideal material for eyeglass casings. Titanium casings can be found in multiple colors.
Beta titanium. This really is an alloy mainly of titanium, with minimal amounts of aluminum and vanadium. These other metals in the alloy create beta titanium more versatile than 100% titanium, for less complicated fitting adjustments.
Memory metal. This really is a titanium alloy composed of about 50% titanium and also 50% nickel. Casings made of memory steel are really flexible and can be twisted or bent to an extreme and still come back to their original form. This feature can make memory metal frames ideal for children or anyone who is hard on their glasses.
Beryllium. This lower-cost alternative to titanium resists corrosion and tarnishing, which makes it a great choice for anybody with higher skin acidity or for anyone who spends a good amount of time in or around salt water. It is also light-weight, strong, flexible and available in a wide range of shades.
Stainless Steel. This is an iron-carbon alloy that also has chromium. Stainless frames are lightweight, strong, long lasting, flexible and corrosion-resistant. They also can be created in matte or polished finishes.
Monel. This is widely used, its affordable material is an alloy of nickel and copper. It is less costly compared to other metals, however – based on the quality of the plating used – monel casings might not discolor and cause skin side effects over time.
Aluminum offers a distinctive look and is therefore mostly seen in the top of the range eyewear. Frames created from lightweight aluminum are light-weight and highly corrosion-resistant.
Plastic material Frames
This material (also known as zylonite or cellulose acetate) is a light-weight and also relatively affordable kind of plastic material. It’s also the most popular plastic material used for eyeglass frames. Zylonite frames are available in numerous colors, such as multi-colored models and casings with different levels of color.
Propionate. It is a nylon-based plastic material that is strong, flexible, light-weight and hypoallergenic. Propionate is often used in sports casings because of the durability.
Nylon. This frame material is still occasionally used. Nylon is strong, light-weight and also flexible, however, it can be brittle with age. Because of this, it has for the most part been changed by nylon mixes – polyamides and also gliamides – that is stable.
As you might guess, these are casings that have both metals as well as plastic components. Popular in the 1950s and 1960s, combo casings make a comeback, in a larger number of colors compared to the vintage models.
