Durable Glasses Frames – 2019

The glasses frames are made of plastic, metal and other materials. Metal is the toughest eyeglass frame material with six metallic options to choose from. But two metals are considered the most durable: Flexon and Titanium, where steel equals titanium but offers fewer color choices. One of the three plastic frame materials also lands on the most stable sunglasses list: nylon.

The durable eyeglass frames can be made of metal or plastic.


Flexon is a hypoallergenic lightweight metallic glass frame that is robust and flexible. It is also resistant to corrosion, making it attractive to those who work, live or participate in different weather conditions. This metal frame is a titanium-permitted metal. One unique aspect of the Flexon chassis is that it can return to its original shape despite rotating, bending, or pinching the chassis, according to All All Vision. For this reason, bending is known as "memory metal".


The second most durable sunglasses frame is a nylon plastic frame. This is not the nylon frame that was introduced in the 1940s. This is a mixed nylon. Just like the Flexon, this frame is lightweight and powerful. It is also hypoallergenic and flexible. As a nylon frame, it can be coated with many different colors, which offers a choice that is not durable. According to All About Vision, sports enthusiasts usually prefer nylon frames because they are better able to withstand heat and cold and provide greater flexibility than metal. However, they break down more easily than metal frames and their overall strength is inevitably reduced by solar radiation and the aging process.


Titanium and titanium alloy metals are used to make some of the toughest eyeglass frames. Their durability is actually comparable to stainless steel, but with titanium frames they offer more choices than stainless steel in terms of textures, designs and colors. Lightweight, durable and corrosion resistant titanium and titanium alloy frames (titanium combined with nickel or copper) were even used for Apollo and Gemini space shuttle capsules. The medical community uses titanium for medical implants, such as heart valves, further demonstrating their durability even under conditions of humidity and other extreme conditions. When cost is a factor, titanium alloy frames cost less than 100 percent titanium frames.
