Abstract

The present invention provides a functional sheet including a functional layer provided between protective layers. The functional layer is a polarizing film layer, a photochromic layer, or a combination of the polarizing film layer and the photochromic layer. At least one of the protective layers includes a layer formed of a resin (C) containing a polyester resin (A) obtained as a result of polycondensation of 1,4-cyclohexanedimethanol and 1,4-cyclohexanedicarboxylic acid and an aromatic polycarbonate resin (B), the polyester resin (A) being contained at a content of 10 to 100 parts by mass and the aromatic polycarbonate resin (B) being contained at a content of 0 to 90 parts by mass with respect to 100 parts by mass as a total of the polyester resin (A) and the aromatic polycarbonate resin (B). A lens is provided with such a functional sheet.
