Eyeglass frame finish refers to the final exterior treatment applied to the frame material (metal or plastic). The finish determines the frame's aesthetic appearance, such as whether it is shiny, matte, brushed, or has a specific color coating.

Frame durability is highly dependent on the finish type. Advanced finishes like PVD (Physical Vapor Deposition) and ion plating bond the color at a molecular level, offering maximum resistance to chipping and fading compared to standard painting or electroplating.
For plastic frames, the finish is often achieved through polishing or tumbling the material (acetate). Injected plastic frames may use dyes or surface lacquers. The finish determines the depth, clarity, and texture of the plastic.
The finish is the most visible aspect of the frame, giving it character (e.g., glossy, matte, textured). Beyond looks, a quality finish prevents metal allergy reactions by sealing the base metal away from the skin, which is a major factor in frame longevity and wearer comfort.
PVD (Physical Vapor Deposition) is considered one of the most durable metal finishes because the coating is chemically bonded to the metal.
Yes, minor scratches on plastic frames can sometimes be buffed out by an optician. Damaged metal finishes require specialized replating.
A high-quality finish makes the frame surface smoother, reducing friction and improving skin comfort.
If your frame finish is peeling or "pitting," the base metal (often containing nickel) may be exposed. This can cause severe contact dermatitis (rashes). Consult your doctor for skin treatment and ask your optician about switching to a hypoallergenic titanium frame with PVD finish.
