Metal is one of the most commonly used materials for eyeglass frames, and metal frame glasses were one of the first eyeglass frames that continue to provide us with a wide variety of styles today. Of course, metal glasses frames can last for a long time in most cases because of the material. Some precious metals are also slowly being used in the production of eyeglass frames, the more conventional titanium glasses frame.

Simply put, eyeglass frames made from various types of metal are metal frame glasses. For example, the common nickel-copper alloy, titanium alloy, aluminum alloy, etc. Metal glasses frames and other materials are stronger, can be used for a long time without deformation, and are most suitable for use with prescription lenses.
Metal frame glasses are generally fine for 1-2 years if used in a regular environment. If you happen to be more careful in your daily use and often maintain it, about 5 years is not a problem at all.
