[0002] Optical lenses are the core component of glasses. Their main functions are to correct vision, protect the eyes and provide a comfortable visual experience. Resin lenses are currently the most widely used lens material. Resin lenses are light in weight, impact-resistant, not easy to break, and safe and comfortable to wear. At the same time, resin lenses have a higher refractive index. With the same degree, the lenses can be made thinner and more beautiful in appearance. However, resin lenses have relatively poor wear resistance, are easily scratched, and have slightly lower light transmittance than glass lenses.

[0003] When performing the grinding operation, the existing optical lenses need to be clamped and fixed, and their positions need to be constantly adjusted during the clamping operation, which increases the difficulty of the processing operation, and only one can be input for processing at a time, thereby reducing the grinding efficiency of the lenses. Therefore, the present invention proposes an efficient grinding device and method for optical lens processing. Summary of the invention
