PROGRESSIVE REFRACTIVE POWER LENS AND METHOD FOR DESIGNING THE SAME

PROBLEM TO BE SOLVED: To provide a progressive refractive power lens which is suitable for a user with high use frequency of intermediate distance.SOLUTION: In a progressive refractive power lens 10 for spectacles having a far focal part 11, a near focal part 12, and an intermediate part 13 with different visual power, the intermediate part 13 is provided with: a first area 131 which is connected to the far focal part 11, and includes a first visual power gradient D1; a second area 132 which is connected the near focal part 12, and includes a second visual power gradient D2; and a third area 133 which is located between the first area 131 and the second area 132, and includes a third visual power gradient D3. The first visual power gradient D1, the second visual power gradient D2, and the third visual power gradient D3 satisfy the following condition: (1) |D3|
