Abstract:

Disclosed are an optical lens (100), glasses and a display device. The optical lens (100) comprises a first surface (110), a second surface (120), a main focusing part (140) and a secondary focusing part (150). The optical lens (100) is a convex lens; the first surface (110) and the second surface (120) are two side faces of the optical lens (100); the first surface (110) is a raised aspheric face; and the second surface (120) is a recessed curved-base Fresnel face. The main focusing part (140) and the secondary focusing part (150) are arranged adjacently and connected in a direction perpendicular to a main optical axis (130) of the optical lens (100). A first focal point (P1) of the main focusing part (140) and a second focal point (P2) of the secondary focusing part (150) are both located on the main optical axis (130), and the focal distance of the secondary focusing part (150) is greater than the focal distance of the main focusing part (140).
