Expert Answer:

Refraction of light doesn't mean bending of light ray away or towards the normal. Bending if light happen because light velocity get changed when it travel from one medium to another medium. And this can only happens at the surface of contact between two different  optical medium. That's we call Refraction as surface phenomenon.
