Abstract:
The eyewear material is an eyewear material containing thermoplastic polyurethane. The eyewear material has a tan δ peak at both less than 0° C. and 0° C. or more and 70° C. or less observed in dynamic viscoelasticity measurement in tensile mode under the measurement conditions of a temperature increase speed of 5° C./min and a measurement frequency of 10 Hz.
