Abstract
An optical lens for vision correction includes a first image fusion area centered on a visual axis (L) of the eye (E) of a user and including a plurality of first dioptric portions randomly arranged around the first image fusion area and fused to have a first diopter (N), and a second image fusion area connected to and surrounds the first image fusion area and including a plurality of second dioptric portions randomly arranged around the second image fusion area and fused to have a second diopter (M). The first diopter |N| is smaller than the second diopter |M|. The longest width of each of the first and second dioptric portions relative to the visual axis (L) is smaller than 200 nanometers.
