My dad had a small stroke that left him unable to see in one eye. But being neurological, this wasn't exactly like losing sight.
If someone sitting next to him spoke, and he wasn't facing them with his remaining working eye, he would be taken by surprise, and would not always understand who was talking to him. Instead of turning his head, he would frequently ask, "Who's that? Where are you?" It wasn't just that he couldn't see the person, it was almost as if the person wasn't there. He frequently described how the blind side of his vision wasn't black, just "not there".
Another oddity was that he didn't notice the loss of vision until maybe a couple of days after it happened.
The same thing happened to my mom after her stroke.
There wasn't a black spot in her field of vision, it was a kind of indefinite background that didn't stand out, but didn't have any information. Her best explanation is that it was like your peripheral vision, you can "see" things to the side, but you're not getting 100% of the detail you'd get if it was in front.
But yes, she said the same thing - it freaked her out when she would move her eye slightly and something that was hidden by the blind spot popped up.
