Abstract
An aspheric lens using an E-value to control an eyeball growth rate and a method of manufacturing the same are disclosed. A treatment zone of the aspheric lens includes a base curve having non-zero eccentricity, and the base curve can make the image shell formed on a retina have non-zero eccentricity, so as to increase a peripheral defocus area formed on the retina to effectively control myopia or hyperopia, thereby achieving the purpose of correcting myopia or hyperopia.
