1. An asymmetrical lens of an image sensor module comprising:an optical axis;

a front surface comprising a first set of normal axes (x, y) in a plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x, y); and

a back surface comprising a second set of normal axes (x?,y?) in the plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x?,y?),

wherein the asymmetrical lens has positive refractive power in the x-axis and negative refractive power in the y-axis of the image plane of the asymmetrical lens,

wherein refractive power in the x-axis and the y-axis of the image plane differ, and

wherein the front surface comprises a negative radius of curvature normal to a positive radius of curvature along the first set of normal axes (x, y) and the back surface comprise a negative radius of curvature normal to a positive radius of curvature along the second set of normal axes (x?, y?).

a front surface comprising a first set of normal axes (x, y) in a plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x, y); and

a back surface comprising a second set of normal axes (x?,y?) in the plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x?,y?),

wherein the asymmetrical lens has positive refractive power in the x-axis and negative refractive power in the y-axis of the image plane of the asymmetrical lens,

wherein refractive power in the x-axis and the y-axis of the image plane differ, and

wherein the front surface comprises a negative radius of curvature normal to a positive radius of curvature along the first set of normal axes (x, y) and the back surface comprise a negative radius of curvature normal to a positive radius of curvature along the second set of normal axes (x?, y?).
