A safety lens has a protection panel and a dioptric component. The protection panel is transparent, flat and non-dioptric. The dioptric component is formed on the protection panel to provide a dioptric effect for a myopic or presbyopic wearer to allow the wearer to see through the dioptric component clearly. Therefore, the myopic or presbyopic wearer can see a workpiece through the dioptric component to perform detailed operations or through the protection panel to relax eyes when performing normal operations.
