"WebOriginally, the concept was developed in geometrical optics for calculating the propagation of light rays with some transverse offset r and offset angle θ from a reference axis (Figure 1). As long as the angles involved are small enough (→ paraxial approximation), there is a linear relation between the r and θ coordinates before and after an optical element.

WebEven 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.

WebA thin lens is one whose thickness is small compared to the other characteristic distances (e.g., its focal length). The surfaces of the lens can be either convex or concave, or one surface could be planar. Because of the refractive properties of its surfaces, the lens will either converge or diverge rays that pass through it.
