As we all know, titanium is a strong light silver-white metal that is used to make aircraft and spacecraft. Recently, it has been used in making eyeglass frames and this kind of frames have become immensely popular among people.
The reason for its popularity is that the pure titanium eyeglass frames have many merits that traditional frames have not. The most obvious one is that they are much lighter. Normally, a titanium frame weights only 9gram, about 50% lighter than other metal frames. You can imagine how comfortable our nose would be if we wear this kind of eyeglass frames. Another merit is that they can never be corroded. |
