We missed extreme farsightedness until age four or five. He didn't know any better and since he read all the time, worked on puzzles and did artwork for hours, there were not many signs. (Despite the name, farsightedness is not really being able to see far, another thing we learned.)

The first person he saw didn't diagnose just how bad his eyes were (let's say he got approximately half the prescription strength he needed). A few years later, the real situation was assessed and it definitely helped him in school.

So, yes, it's so possible to miss it when it's always been that way for the child!
