Ocular optical system
An ocular optical system has four lens elements, wherein the ocular optical system includes a first lens element having a display-side surface with a convex portion in a vicinity of its periphery, and a third lens element having an eye-side surface with a convex portion in a vicinity of its periphery. In addition, υ1 is an Abbe number of the first lens element, υ4 is an Abbe number of the fourth lens element, and the ocular optical system satisfies the relationship 20.00≤|υ1−υ4|.
