Have you ever seen the show That's So Raven? It's about a teen girl who's a psychic and she can see the future, so at the start of the episode she'd see something like a bucket of paint getting dropped on her and ruining her new dress, so she does all these whacky things to keep it from happening...but it happens anyway in a way she may not expect at all. One time she saw her kissing her crush and she was all excited because she thought that it meant they were going to get together, but he ended up kissing her for some sad reason and he didn't have the same feelings for her.
We all have expectations to things and we jump to conclusions when we don't have the full story. If you got out of a movie and saw you had 5 missed calls from your mother, what are you going to assume it's going to be? Probably something really bad happened and she needed to get ahold of you. But maybe a grandkid was playing with her phone, or she buttidaled you a lot, or she needed to test if her phone worked and just used your number as a test. So your character having a premonition or a more literal seeing of things of the future won't have the full context of what's going on, so his biases and preconceived notions are going to cause him to assume things, like how Raven assumed the kiss with her crush was because he would like her, too.
Funnily enough I also have a blind character but he doesn't get visions, he just helps a seer with hers. But he was born blind so he has to be taught what things look like. If he sees something outside, for example, knowing what the grass or trees look like at different times of year can help him figure out when the vision is going to take place, but since he's never seen these things himself he has to be taught these things. He has magic so he can sort of "ride" on someone else's senses to see for a bit but someone still had to sit down with him and tell him the difference between green and brown grass.
When did your character lose his sight? How blind is he? Most blind people can see SOMETHING, but it's usually so poor quality it doesn't help them much. There are plenty of animals whose "eyes" are just binary "is that a shadow above me" type things and they manage perfectly fine, but our society is based around being able to see things and make decisions based on that. If your character has been blind/low-vision all or the majority of his life, he might not know how to read "regular" written language, so if he gets a premonition of a news broadcast and the volume is off, he won't be able to read the BREAKING NEWS! PRESIDENT ASSASSINATED and would be missing the most important part of what's going on. Though he could definitely learn how to read "regular" writing, but it would require finding specialists and specific devices to create raised print and not just braille. If this takes place in a modern society, there are going to be non-profits that help blind/low-vision people learn the skills to successfully navigate the world, especially people who lose their vision later in life.
