Abstract:
Present embodiments provide for ocular optical systems. An ocular optical system for imaging of imaging rays entering an eye of an observer via the ocular optical system and a pupil of the eye of the observer from a display screen, may comprise four lens elements positioned sequentially from an eye side to a display side. By controlling the refracting power and the surface shape of the lens elements and designing parameters satisfying at least one inequality, the ocular optical system may exhibit better optical characteristics and the half apparent field of view of the ocular optical system may be broadened.

Claim (Index 14):
The ocular optical system of  claim 11 , wherein\n T3 is a central thickness of the third lens element, T4 is a central thickness of the fourth lens element; and AAG, G4D, T3 and T4 satisfy the inequality:\n ( AAG+G 4 D )/( T 3+ T 4)\u22645.
