Abstract: A bicontinuous microemulsion of water, a monomer, and a surfactant copolymerizable with the monomer is polymerized to form a polymeric material, the polymeric material comprising a polymer matrix defining interconnected pores. The polymeric material may additional comprise at least one photochromic agent and/or UV-absorbing agent. The at least one photochromic agent and/or UV-absorbing agent may be dispersed in one or both of the polymer matrix or the interconnected pores. The polymeric material may be used to form photochromic articles including ophthalmic articles such as contact lenses.
