摘要： The invention provides an optical article including a substrate; and a colorant composition connected to at least a portion of the substrate. The colorant composition is a fixed-tint colorant; and a photochromic material. The article exhibits a passive state and an activated state, such that the article can switch from the passive state to the activated state in response to at least actinic radiation and to revert back to the passive state in response to thermal energy. The passive state is characterized by a transmittance ranging from greater than 30% to 70% across a wavelength range of from 460 nanometers to 500 nanometers.
