First, hold the lens by its edge and never touch the lens surface with your fingers. Moisture from your fingers can sometimes damage the lens cover, and if your fingers stay on the lens surface for a long time, it will become a stain. Even if you wear gloves, avoid touching the lens surface;

Second, do not handle the lens with metal tools or pliers. Using wooden, bamboo and plastic tools to handle the lens will reduce the chance of lens damage. For small lenses, you can use a handheld vacuum pen;

Third, keep the lens on a soft surface, especially if the optical surface is raised. Placing it still on a hard desktop will cause surface scratches;

Fourth, for lens systems or assemblies, covering the lens cap when not in use can protect the optical surface from damage;

Fifth, when storing lenses, they need to be wrapped separately in a clean, soft lens box and placed in a safe place. Never put unwrapped lenses together in a box or bag, because they will be damaged by contact with each other. Never put them under heavy objects.
