Sunglass frame materials – an overview
Various materials are used in the manufacturing of glasses today, with designs for every taste. Likewise, sunglasses come in all shapes, colours and sizes, and their frames can be made from metal, plastic or natural materials.
Your choice of frame material depends largely on what you want your sunglasses to be able to do. The materials offers different advantages when it comes to weight, flexibility and stability. Here we’ll introduce the most common materials.
Sunglasses made out of metal
Stainless steel is far less likely than some materials to irritate the skin. It’s robust, corrosion-resistant and has high elasticity.
Titanium Sunglasses score highly when it comes to weight, being up to 50% lighter than other frames. Titanium is a high-quality material that requires skilled workmanship, and this tends to be reflected in the price. As titanium contains no nickel it can be a good choice for people with allergies.
Weight is also a benefit of aluminium frames, which are very comfortable to wear. Another advantage is their resistance to corrosion.
At a glance: Advantages and disadvantages of metal
Metal offers one clear benefit: it’s robust, making much thinner frames possible. It’s also scratch-resistant and more difficult to break than other materials.
Sunglasses with metal frames tend to look discreet and subtle, making them ideal for a more elegant, serious look. Various colours can be achieved by alloying with other metals.
Metal frames aren’t suitable for sports. Over time they don’t react well to sweating and they are more likely to cause injury.
Allergy alert: To be on the safe side, go for frames that don’t contain nickel or copper.
