Summary:An ocular optical system configured to allow imaging rays from a display image to enter an observer's eye through the ocular optical system so as to form an image is provided. A direction toward the eye is an eye side, and a direction toward the display image is a display side. The ocular optical system sequentially includes a first and a second lens elements from the eye side to the display side along an optical axis. Each lens element includes an eye-side surface and a display-side surface. One of an optical axis region of the eye-side surface of the first lens element and an optical axis region of the display-side of the first lens element is plane. An optical axis region of the eye-side surface of the second lens element is plane. Lens elements of the ocular optical system are only the two lens elements. The ocular optical system satisfies following conditional expression: 0.400 ≤ T1/T2 ≤ 2.000.
