Abstract
One embodiment of the invention provides an optical lens including a first lens group with at least two lenses, a second lens group with at least two lenses, and a parting line located between the first lens group and the second lens group. Each of the lenses of the first and the second lens groups is associated with a respective distance, the respective distance is a distance value measured along an optical axis between two focal points of two end points of an image circle diameter formed at an image plane of the optical lens, under the condition that an optical center of one of the lenses is shifted a distance away from the optical axis. The two lenses with the two largest distance values among all lenses are disposed on the same side of the parting line.
