A laser protection variable transmission optical device ('LP-VTOD') includes first and second cells, each capable of changing from a state of higher light transmittance to a state of lower light transmittance. The first cell is characterized by a narrow band absorption having a first peak absorption wavelength and a first FWHM of 175 nm or less, and the second cell is characterized by a narrow band absorption having a second peak absorption wavelength and a second FWHM of 175 nm or less. The first peak absorption wavelength may be the same or different than the second peak absorption wavelength. The LP-VTOD is capable of switching from a clear state to a darkened state having a darkened state transmittance % Tthat is equal to or less than 10% for at least one of the first or second peak absorption wavelengths.
