Since, the center of curvature and focus lies behind the convex mirror, signs of the radius of curvature and focal length are taken as + (positive) in the case of the convex mirror. In the case of a convex mirror, images are always formed behind the mirror, thus the distance of the image is taken as positive. Focal length of a convex lens is positive. Whereas focal length of a concave lens is negative, according to the sign convention. Because the object is always on the lens's left side, the incident light always moves from left to right.
