This is my opinion for what it is worth. It is a well known fact that much of society communicates through the eyes and for those without sufficient eye sight to do this, it is a definite drawback. For blind persons who are unable to make eye contact, it is a definite barrier to the sighted world. Remember the famous saying that says "The soul is through the eyes?" Well, for blind persons, they are unable to see one's soul and in turn it is often extremely difficult for the sighted world to see their soul. Not very difficult to comprehend if you think about it.
Blind persons do not and are unable to communicate through the eyes because they are unable to make eye contact but for those who were born with vision and then lose it later on; they have already had the ability to make eye contact and after losing vision they are still able to use their eyes to somehow communicate with sighted persons. That's because they have learned to do this and can still visualize enough to keep on using it. So, let me just summarize below.
If a person is born blind, they are almost always unable to make eye contact. If they have been born fully sighted and lose their vision later on, then they have already developed the technique of eye contact and so are able to visualize enough to simulate eye contact. As for me, I was born blind so I have had to work very hard to develop a way to make eye contact using creativity on my part and tutoring from my mom. Clear as mud?
