PROBLEM TO BE SOLVED: To provide a polarizing lens sheet having a substrate that can easily and reliably be produced, has a sufficient depth, and can be used favourably without inhibiting optical functions.SOLUTION: A polarizing lens sheet 10 includes a base film 20 and a polarizing film 30 to be stacked on the base film 20, can be formed into a three-dimensional curved surface shape by thermal formation, and is used for lenses of polarizing sunglasses. The base film 20 has a thickness of 100 μm or more and 500 μm or less, a visible light transmissivity of 87% or more, a haze value of 2% or less, a surface direction retardation value (Ro value) of 200 nm or less, a depth direction retardation value (Rth value) of 400 nm or less, and includes cycloolefin copolymer as main polymer.SELECTED DRAWING: Figure 2 |
