一种护理用面罩
By designing a nursing mask that includes an arc-shaped support plate, a fixing device, and a light-shielding plate, and using threaded connections and magnetic adsorption, it ensures that blue light is blocked without affecting the field of vision when using a light curing lamp. This solves the problem that existing protective masks cannot effectively filter blue light, and achieves flexible light blocking and comfortable switching of vision.
