A face image processing method and apparatus, a readable medium, and an electronic device, relates to the field of image processing technologies. The method includes: obtaining (101) sight line information in a face image to be processed in accordance with a preset recognition algorithm, where the sight line information includes: a first coordinate and an edge coordinate for an eye, and the edge coordinate is used to indicate an intersection of a sight line of an eye and an edge of the face image; determining (102) a target area in the face image according to the sight line information, where the target area includes a sight line segment with the first coordinate and the edge coordinate as endpoints; and rendering (103) a preset effect material to target area to obtain a target image.
