first of all understand what is lateral displacement ??
Lateral displacement :- Perpendicular separation between incident rays and emergent rays .
→ The rays of light passing through optical centre so, straight after refraction without changing their path .
hence, Lateral displacement equals zero
→ when light rays strike with optical centre and inclined specific angle with principal axis , , due to medium change, refraction occur two times and light deviate from path in the lens .
hence , here Lateral displacement does greater then zero .
hence, slanting rays will suffer more deviation.
