"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.

Webb28 dec. 2024 · A convex lens is also known as a converging lens and essentially works in the opposite way to a concave lens. It’s curved so that the outer bend of the “bowl” shape is closest to the object, and the focal length is assigned a positive value. The process of ray tracing for a converging lens is very similar as for a diverging lens, with a ... Webb15 aug. 2024 · The three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end of "Image Formation by Lenses."

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.
