[0002] Glasses refer to lenses embedded in frames, which are worn in front of the eyes to improve vision, protect the eyes or for decorative purposes. Currently, the types of lens materials can be roughly divided into glass lens materials, resin lens materials, crystal lens materials, PC lens materials, MR lens materials, etc. Lenses of different materials have their own advantages and disadvantages and are used for different purposes. Due to the different materials, the bearing capacity is also different. In the production process of glasses, the raw materials of the lenses need to be cut.

[0003] When the existing cutting device cuts the lens, the blade is in a fixed installation state and rotates, so the lens can only be moved manually to make the blade cut to the specified position.
