How can staring at someone become a barrier to communication
A2, As Dinglebot points out, gibberish is a common communication barrier. Misheard or misunderstood terms would be another.
Your presumption is false. Eyesight is a boon to communication, not a barrier. Attention to eyesight might distract you from another sense, but the choice is there.

He was famous for coulomb's law
Charles Augustin de coulomb discovered the coulomb's law in the 1780s. and limestone 1820
Coulomb discovered Coulomb's law in 1785 after a series of experiments relating to electromagnetism. He published the findings of his three reports in 1785.
Saint-Coulomb's population is 2,454.
Approximately 6.25E18 electrons in a Coulomb.
The Coulomb. If 1 Coulomb is transmitted per second this is 1 Ampere
One Coulomb is the charge of about 6,241,510,000,000,000,000 electrons, so it looks likea Coulomb would probably be bigger than the charge on one electron.
charles de coulomb was known for the coulomb law.IN FRANCEIT IS A FUNDEMENTAL LAW OF ELETROSTATICS

The coulomb is the SI unit of electrical charge. A coulomb, a unit of electrical charge, is defined as the amount of electric charge transported by a current of 1 ampere in 1 second. There are 6.241506×1018 electrons (or elementary charges) in a coulomb. A link is provided to the Wikipedia post on the coulomb.
1 ampere = 1 coulomb/second 1 coulomb = 1 ampere x second
A coulomb is bigger. Please also note that a coulomb is defined as a POSITIVE charge, while an electron has a NEGATIVE charge. Anyway, the magnitude of a coulomb is much bigger than that of an electron.
