Abstract
The present disclosure provides a lens. The lens includes: an optical portion at a central position; and a bearing portion surrounding the optical portion. The bearing portion includes a first surface, a second surface opposite to the first surface, and a connection surface connecting the first surface with the second surface. The first surface is provided with a first arc surface and a first planar surface. An intersection line between the first arc surface and the first planar surface is a first feature circle for measuring an interfacial decenter. The second surface is provided with a second arc surface and a second planar surface. An intersection line between the second arc surface and the second planar surface is a second feature circle for measuring the interfacial decenter. A radius of the first feature circle is not equal to a radius of the second feature circle.
