Answer:
the main factor of focal length is the actual curvature of the lens itself,although in most cases the thicker the lens tends to have shorter focal lengths, first one must realise that the more curvature there is in a lens the shorter it’s focal length becomes,so if one let us say starts off with a parallel piece of glass 10 mm thick and we wish to have a steep curve the thickness of glass will naturally limit the shape that can be ground out of it, whereas if it was 15 mm thick one can get more curvature out of it, curvature is by far the main thing that affects focal
