WebbA lens is said to be thin if its center is so thin that its optical properties are independent of its shape and form, that is, whether the shape of a convex lens is biconvex, planoconvex, or concave-convex; No matter the shape of concave lens is double concave, flat-concave or convex-concave, the influence of the central thickness on its optical properties can be … WebbConvex Lenses. When an object is placed at infinity, the real image is formed at the focus. The size of the image is highly diminished and point size. When an object is placed beyond the centre of curvature, the real image is formed between the centre of curvature and focus. The image size will not be the same as the object.

WebbEven if the lens' curvature is not circular, it can focus the light rays to a point. It's just an assumption, for the sake of simplicity. We are just learning the basics of ray optics, so we are simplifying things to our convenience. Lenses don't always need to be symmetrical. Eye lens, as you said, isn't symmetrical.
