ABANDONED. children's book, glasses so strong he can see into the ground

[Forscha]

I would've read it in the eighties, and it would've been a library book and probably somewhat old.

I believe the main character deliberately got everything wrong on an eye exam in order to get strong/thick glasses for whatever reason, and then they were so strong that he could see into the ground.

He might've gotten involved with criminals who wanted to find gold, but I'm not sure.

Forscha, are you still looking for this tome or did you find it?
