Optical lens, glasses and display device

An optical lens comprising:

• a first surface;
• a second surface;
• a first lens portion;
• and
• a second lens portion;
• wherein the optical lens is a convex lens;
• the first surface and the second surface are at two side surfaces of the optical lens, the first surface is an aspheric surface that is convex in a direction away from the second surface, and the second surface is a Fresnel surface with a curved base that is recessed in a direction toward the first surface;
• the first lens portion and the second lens portion are adjacent each other and connected in a direction perpendicular to a main optical axis of the optical lens;
• a first focal point of the first lens portion and a second focal point of the second lens portion are on the main optical axis, and a focal length of the second lens portion is different from a focal length of the first lens portion.

A pair of glasses comprising:

• a body;
• a first lens in the body;
• and
• a second lens in the body;
• wherein each of the first lens and the second lens includes an optical lens;
• wherein the optical lens includes:
• a first surface;
• a first lens portion;
• and
• a second lens portion;
• wherein the optical lens is a convex lens;
• the first surface and the second surface are at two side surfaces of the optical lens,
• the first surface is an aspheric surface that is convex in a direction away from the second surface, and the second surface is a Fresnel surface with a curved base that is recessed in a direction toward the first surface;
• the first lens portion and the second lens portion are adjacent each other and connected in a direction perpendicular to a main optical axis of the optical lens;
• a first focal point of the first lens portion and a second focal point of the second lens portion are on the main optical axis, and a focal length of the second lens portion is different from a focal length of the first lens portion.
