Shade numbers on optical filter lenses in safety glasses indicate the level of protection they provide against intense light sources, such as those encountered in welding and brazing operations. Higher shade numbers correspond to greater protection, blocking more light and providing safety against specific types of radiation and brightness levels. For example, lower shade numbers might be suitable for tasks like torch soldering, while higher numbers are necessary for arc welding.
