Abstract
An optical lens including, an object-side surface including an atoric surface element and an eyeball-side surface including an element that cancels a surface power shift produced by the atoric surface element, wherein the atoric surface element causes horizontal surface power at a fitting point to be greater than vertical surface power at the fitting point and causes a difference between the horizontal surface power and the vertical surface power to decrease along a horizontal reference line passing through the fitting point in a direction from the fitting point toward a periphery of the optical lens or causes a sign of the difference between the horizontal surface power and the vertical surface power to change along the horizontal reference line.
