Progressive multi-focus ophthalmic lens with personalized meridian and design method of progressive multi-focus ophthalmic lens

The invention discloses a progressive multi-focus ophthalmic lens and a design method thereof. A focal power value on a meridian line is determined by a vision scene coordinate of work or life of a person who puts on the lens. An object point position curve of an object viewing scene right in front of a user is formed by fitting several key points in the object viewing scene through a segmented Bezier curve. And after setting a target function, searching a Zernike polynomial coefficient by using a genetic algorithm to obtain the rise of the progressive multi-focus ophthalmic lens. The meridian focal power of the obtained progressive multi-focus ophthalmic lens is consistent with the target focal power, and the progressive multi-focus ophthalmic lens has a wide effective visual area. The progressive multi-focus ophthalmic lens obtained by taking the visual scene of the person who puts the lens as the reference not only conforms to the personalized characteristics of the person who puts the lens, but also confo
