Progressive lenses are not a magic but too much of science in it While incorporating the progression from distance to near on a single lens, The same lens needs to have multiple minute curvatures to have multiple powers into it for the vision According to the design and technology while having minute multiple curvatures on the central portion, the peripheral portion of the lens gets abbereted and gets unwanted cylindrical powers . This is how the peripheral distortion in a progressive lens takes place Hope this answers your question 😊
