SOLVED. YA fiction. The main character is almost blind and believes it is because he looked at the eclipse when he was a baby. Read around 2014. Spoiler. [s]

I read this book in 8th grade around 2014. The main details are above, the only other thing I remember is the older brother to the kid was super hateful and mean towards him.

The fact is we did have an eclipse that summer, around three weeks before school started. Based on that, Erik was telling his friends this story: The reason for the Coke-bottle glasses on my eyes was that I had stared at the sun, unprotected, during that eclipse.
