PROBLEM TO BE SOLVED: To provide a spectacle lens with improved visibility.SOLUTION: A spectacle lens 10 includes a pair of lenses 10L and 10R for a left eye and a right eye. Refractive power of one of the pair of lenses 10L and 10R is at a positive side with respect to refractive power of the other lens, and average surface refractive power (base curve) at an object side of one lens is smaller than average surface refractive power (base curve) at the object side of the other lens. Typical refractive power (diopter) is principal meridian refractive power along one principal meridian of a lens, and a typical base curve is a base curve in a direction along one principal meridian. |
