Ion-plated frames are metal spectacle frames that have been colored using an advanced vacuum process. Ion plating (IP) is a durable coating technique that uses electrical charges to bond the color ions to the surface of the metal frame.

The main benefit is superior adhesion. The bond created by ion plating is much stronger than traditional electroplating, making the color layer highly resistant to scratching, corrosion, and fading from sunlight or sweat.
Ion plating is beneficial for people with sensitive skin. By creating a tough, durable barrier, the plating seals the underlying metal (often nickel or steel) from direct contact with the skin, preventing allergic reactions from the underlying alloy.
Ion-plating results in a highly uniform coating that resists abrasion and chemical degradation from skin oils and sweat. This structural advantage means the frame maintains its aesthetic quality much longer than a traditionally plated frame that can fade or flake off quickly.
Yes, ion plating is significantly more durable and chip-resistant than standard electroplating.
Yes, the equipment needed for the vacuum process makes ion-plated frames more costly than standard electroplated frames.
Most metal colors are available, including black, silver, and gold tones, which are highly stable with this process.
If you have severe nickel allergies, look for Ion Plated (IP) or PVD-coated titanium frames. These processes create a dense, non-porous layer that prevents base metal ions from leaching onto your skin, significantly reducing the risk of contact dermatitis compared to standard plating.
