Unless you are an extraordinary minister of Holy Communion, I don’t see how you could tell where anyone receiving is looking.
I happen to be an EMHC, and I find some people look me in the eye when I say to them “Body of Christ”, or The Blood of Christ". and they respond to me with “Amen”, and then look at the Host or the Cup. Others do not make eye contact, but look at the Host or the Cup (both of which are being held up, but not to eye level).
I was also an altar boy, starting in the 1950’s, and some people looked at the Host, and some had their eyes closed. No one made any response to the priest.
I am not going to argue with your parents, but I can see nothing wrong with looking at the priest or the EMHC, as they are addressing you directly and you are responding to what they say. Nor is there anything wrong with not looking at the individual; but I certainly would not teach someone to not look directly.
In the instructions which the Church provides as to how Communion is distributed, nothing is said as to where the communicant is to look, or not look.
And we do not normally refer to the Host as “bread” once it has been consecrated; St Paul to the contrary.
I teach RCIA, and nothing has ever come up on the matter as to where one is to look; I certainly would not teach that they cannot look, or should not look at the individual they are receiving from; nor that they should look.
