The present invention aims to provide a photochromic compound capable of exhibiting photochromic properties regardless of matrix, and the compound is stably dispersed without aggregation in a process of molding (curing) an optical base material. According to the present invention, a polymer photochromic compound, which has a block polymeric group of an oligomeric chain group having relatively favorable compatibility with a solid matrix and an oligomeric chain group having poor compatibility with a solid matrix, forms a nano- to micro-phase separation structure in a solid matrix. The compound does not rely on the solid matrix, its dispersibility is improved and aggregation is prevented or reduced, whereby excellent photochromic properties can be exhibited.

A wearable device including a body having one or more embedded electronic components, the body further including a thermoset material having a polymeric backbone with at least one urethane linkage and a glass transition temperature. At a first temperature that is lower than the glass transition temperature, the body has an original shape. When the body is heated to a second temperature that is higher than the glass transition temperature, the body is deformable from the original shape to a first shape and when the body is cooled to a third temperature that is lower than the glass transition temperature, the first shape is maintained. The body is further configured to transition from the first shape to the original shape when the body is heated from the third temperature to a fourth temperature that is higher than the glass transition temperature.
