The New Cartesian Sign Convention for spherical lenses is explained as follows:
We generally take it to be negative i.e. (-ve) when we consider it from the pole i.e. P of a mirror that is spherical in shape. It has to be directed towards the object and has to be along the principle axis.
This convention also states a very important point. It states that we always consider sign to be negative, when we consider from the front of a mirror that is spherical in terms of shape.
The overall feature is an important property of "Reflection and Refraction property of Light".
