Antibacterial spectacle part and antibacterial treatment method

An antibacterial treatment method comprising:

• dissolving dopamine in an alkaline solution to form a first treatment solution and immersing a spectacle part in the first treatment solution, to cause the dopamine to undergo a self-polymerization reaction to form a film on at least one surface of the spectacle part;
• and
• immersing the spectacle part in a second treatment solution comprising silver nitrate and aqua ammonia, to cause the silver nitrate and catechol groups of the dopamine on a surface of the film away from the spectacle part to undergo a redox reaction, so that silver icons of the silver nitrate are reduced to silver nano particles which are deposited on the surface of the film;
• wherein the film further comprises inorganic oxide particles selected from a group consisting of silicon dioxide nano particles, zirconia nano particles, and aluminum oxide nano particles, the alkaline solution is formed by mixing ethyl alcohol, water, and aqua ammonia.
