When it comes to choosing a frame, most people worry about price and style. However, there are other important factors to consider such as the light weight, strength, flexibility, and corrosion resistance. Frames are made of various types of plastic and metal. Some frames combine materials — for example, a frame with plastic around the lenses and with the hundreds of pieces made of titanium. Here are some facts about metal and plastic frames so you can pick the right one for you.
Metal, titanium, or a mixture of metals can handle heavy use. Titanium frames are very strong, lightweight and anti-corrosive. They are hypoallergenic - an important consideration for those with allergies to some metals like nickel. These frames can be a good choice for older children because they are sturdy.
Monel is a mixture of metals. Although these frames may have nickel or other metals that can cause allergic reactions, most monel frames have a coating that protects the skin. Monel frames are very flexible and anti-corrosive.
Beryllium frames are less expensive than titanium frames and the material is very light and strong. It is also flexible. Berillium is extremely resistant to corrosion. They can be a good alternative for those who spend a lot of time in or near sea water.
Stainless steel frames are light and strong but not as light as titanium frames. They can be less expensive than other metal frames and are also anti-corrosive.
Flexon frames, as the name suggests, are made of a very flexible material. Flexon is a titanium alloy that recovers its shape even after it has been twisted or bent. These frames are lightweight, anti-corrosive and hypoallergenic.
Aluminum is sometimes used in high-end frames. It is anticorrosive, flexible and resistant.
Plastic frames are the most popular because they are generally less expensive, lightweight, and come in a variety of styles and colors. If you need a budget wise alternative for an occasional use this can be the right material for you. One disadvantage is that they break more easily than metal frames.
Types of plastic frames include:
Zyl (zylonite, or cellulose acetate) is an inexpensive, lightweight material that comes in multiple colors.
Cellulose Acetate Propionate is a lightweight, nylon-based, hypoallergenic plastic. May be slightly softer than other plastic frames.
Nylon Blend Frames. These frames are strong and lightweight and very popular for sports eyewear frames or safety frames. Nylon frames are often found in wrap-around styles because they can be easily molded.
Frameless or perforated frames are lightweight. Trivex or polycarbonate lenses work well with these types of frames.
