we know magnifying power of convex lens of small focal length is large then what prevents us to form a convex lens for very small focal length to have a very large magnifying power explain

a lens of very small focal length suffers from both spiracle and chromatic aberrations this celebrations are very large and hence the quality of the images very not good moreover it is very difficult to manufacture a lens of not small focal length .

A lens is a clear object, usually made of glass or plastic, which is used to refract, or bend light. Lenses can concentrate light rays (bring them together) or spread them out. Common examples of lenses include camera lenses, telescope lenses, eyeglasses, and magnifying glasses. Lenses are often double lenses, meaning they have two curved sides. A convex lens is rounded outward, while a concave lens curves inward. (A great way to remember this is that a concave lens creates an indent like a cave!)
The center axis through a lens is called the principal axis. On lenses that concentrate light rays, the point at which the rays meet, the focal point, is located on the principal axis. The distance the focal point is from the surface of a lens is called the focal length of a lens, and is important when determining the magnifying power of devices like magnifying glasses.
