PROBLEM TO BE SOLVED: To provide the plastic lens which has no interference fringe, superior outward appearance, and excellent resistance to a rub, wear resistance, and shock resistance at low cost by using plastic lens base materials which have various refractive indexes. SOLUTION: An intermediate layers 12 which has a refractive index difference of <=0.03 while a plastic base material 11 and the had coat layer 13 has a refractive index difference of >=0.08 is provided between the plastic lens base material 11 and hard coat layer 13 and the whole of the hard coat layer 13 and intermediate layer 12 can be regarded as optically one layer, thereby providing the plastic lens which has no interference fringe, superior outward appearance, and excellent resistance to a rub, wear resistance, and shock resistance at low cost. |
