According to the American Optometric Association,
signs of learning-related vision problems in a child,
which parents and teachers should look for, include:
Losing place and skipping words when reading

Complaints of blurry vision

Closing or covering one eye when reading

Short attention span

Trouble finishing written assignments

Errors when copying from the board

Poor reading comprehension

Moving head excessively when reading

Performance below a child's potential

Any child who is having difficulty in school should be evaluated for
vision problems. A comprehensive vision examination can either
rule them out as a contributing factor or identify and correct vision
problems that are impacting the child's ability to learn.

Studies show that once a learning-related vision problem is
diagnosed and treated, the child will be able to perform much more
effectively in the classroom.

Vision Problems Can Be Learning Problems!
A study of school-aged children found
that those with eye focusing and eye
teaming problems had a higher
frequency of behavior problems, which
affected their school performance and
attention in the classroom.
Uncovering Hidden Vision Problems

It's not always easy to pinpoint an exact reason why a child isn't doing well in
school. Frequently, learning difficulties are due to a combination of problems.
But when children struggle in school or perform below their potential, an
undiagnosed vision problem may be the cause.

Having a vision problem makes it harder for children to learn. The extra effort
needed to compensate for poor vision makes it more difficult to remember and
understand what they see. The harder they try, the more likely they will
develop symptoms of discomfort and fatigue.

When children try to read fuzzy words on a page or are unable to accurately
move their eyes from one word to another, their reading performance suffers.
Regardless of how motivated to learn a child may be, continuing reading failure
can lead to frustration and behavior problems in the classroom and at home.

Some children with learning difficulties exhibit specific behaviors of
hyperactivity and distractibility. These children are often labeled as having
"Attention Deficit Hyperactivity Disorder" (ADHD). However, vision problems
can elicit some of the very same signs and symptoms. Some children may be
mislabeled as having ADHD when in fact what they have is a learning-related
vision problem.
