摘要： An ocular optical system adapted for an imaging ray of a display image being entered an observer's eye through the ocular optical system to form an image is provided. The ocular optical system includes a first lens and a second lens arranged in order from an eye-side to a display-side along an optical axis. Each of the first lens and the second lens has an eye-side surface and a display-side surface. A maximum distance between the display-side surface of the first lens and the eye-side surface of the second lens parallel to a direction of the optical axis is less than 5 millimeters, and the ocular optical system satisfies: 6≦DLD/EPD≦20. DLD is a diagonal length of the displayed image corresponding to a single pupil of the observer, and EPD represents an exit pupil diameter of the ocular optical system.

摘要： An ocular optical system includes a first lens element, a second lens element and a third lens element from an eye-side to a display-side in order along an optical axis. The first lens element, the second lens element and the third lens element each include an eye-side surface and a display-side surface. The eye-side surface of the first lens element has a concave portion in a vicinity of the optical axis. The display-side surface of the third lens element has a concave portion in a vicinity of a periphery of the third lens element. The ocular optical system satisfies 1≤TTL/ER≤10, wherein TTL is a distance from the eye-side surface of the first lens element to the display screen along the optical axis, and ER is a distance from a pupil of the observer to the eye-side surface of the first lens element along the optical axis.
