The early main frame material using metal and hawksbill, in recent years has stainless steel, titanium, copper, plastic and monel, nickel alloy material, etc.

In recent years, frame also has many breakthroughs in technology and application of materials, USES the memory alloy frame glasses, can maintain its shape, even if the buckling will not break, the glasses have a longer life, also avoid frames break any inconvenience caused. The frame arm of ground join spring at the glasses more durable.

While titanium metal frames, lighter, more corrosion resistance, to avoid long-term wear because of the sweat on metal corrosion and lose luster.
