Optical centre :

the optical centre of a lens is a special point on its principal axis A Ray of light passing through the optical centre of a lens goes straight through it without undergoing any bending or deviation from its path

Focus :

focus is also known as principal focus it turns out that if a beam of rays all parallel to the principal axis of a lens falls on the lens all such rays either all converge to a point on its principal axis or appear to diverge from a point on its principal axis

Hope helpful for you mate
