摘要： Described are photochromic articles that include a substrate and a photochromic amount of at least one organic photochromic material (b) represented by graphic formula XIII adapted to change from an unactivated state to an activated state by exposure to radiation substantially in a wavelength range from 380 to 410 nanometers (nm) when measured over a wavelength range of from 380 to 700 nm. The photochromic articles demonstrate a photochromic response when activated behind an ultraviolet blocking transparency such as an automotive windshield. For example, the photochromic articles retain at least 12 percent of the activation measured as change in optical density or delta OD under outdoor simulating conditions in the Outdoor Test when tested under conditions simulating an eyeglass wearer behind an automotive windshield in the Behind the Windshield Test. Methods for producing the aforedescribed photochromic articles are also described.

摘要： Described are photochromic articles that include a substrate, a temperature dependent reducing amount of at least one organic photochromic material (b) that changes from more absorbing to less absorbing of radiation in its activating spectral absorbance as the temperature increases from 10° C. to 35° C. and at least one other photochromic material (c) that is different from photochromic material (b). In the article, photochromic material (b) is interposed between photochromic material (c) and a source of activating radiation. The photochromic article demonstrates a more consistent photochromic response, for example, an optical density response loss of 50 percent or less over a temperature range of from 10° C. to 35° C. as measured in the Photochromic Temperature Dependence Test. Methods for producing the aforedescribed articles are also disclosed.

摘要： Described are contact lenses having photochromic materials within the central or pupillary area of the lens and methods for manufacturing such lenses. In one method, a photochromic amount of at least one photochromic material is added to the pupillary region of a casting mold containing a polymerizable monomer that can be at least partially cured before and/or after the addition. Another method involves providing an amount of polymerizable photochromic monomer for the pupillary region and an amount of polymerizable non-photochromic monomer for the remainder of the contact lens in a casting mold. The photochromic and non-photochromic monomers can differ by their degree of polymerization, viscosity and/or density.
