Zusammenfassung:In a lens for safety glasses of the present invention, a first lens element which shields a laser beam is laid on a second lens element for antiglare. The first and the second lens element may be affixed together. In the lens for safety glasses, the first lens element includes a substrate which contains an absorbent for selectively absorbing a laser beam having a specific wavelength in an ultraviolet wavelength region, a visible light wavelength region or an infrared wavelength legion and is transparent in the visible light wavelength region. The safety glasses with the lens may provide comfortable fit and a good appearance, causes less misjudgment of colors and prevents loss of correct color sense, and has both a laser-beam shielding function and an antiglare function.
