What is making it hard to read for so many people? My eyes aren't young or healthy, but it is as clear as day for me. Wonder with screens play are role.

Maybe part of it is the natural genetic variation in humans. I could read it, but it wasn't easy for me. My eyes are old too.

For me it's astigmatism. I have fairly mild astigmatism and I can just barely read the text if I try very, very hard.
