Teacher’s Guide to Vision

Published April 7, 2020

It may surprise you to discover that many students in your class actually have vision problems at the root of their learning difficulties.

“It is estimated that more than ten million school age children suffer from vision problems that may cause them learning difficulties in school.” (National PTA)

If vision problems are missed during crucial times in development, a child’s eye health, development, and learning performance may be negatively affected.

As an educator, you play a vitally important role in the future success of your students. You are the most qualified professional to notice any learning problems in the classroom.

What every teacher should know about their students’ vision:

  • 80% of all learning is obtained through a person’s vision.
  • 60% of students identified as “learning difficulty” have undetected vision problems.
  • Children may not recognize their vision difficulties because they have “always seen this way”, and gradual changes may go unnoticed.

There is a false belief that because a child sees an eye chart across the room clearly that they have perfect vision. A measure of “20/20” is simply the ability to see at 20 feet away, which has little to do with reading, attention and the other tasks required for successful academic performances.

School vision screenings are limited

School vision screenings might detect myopia or significant lazy eyes, but many other vision problems can be missed. A school vision screening is not a substitute for a comprehensive eye examination from an eye doctor.

  • Vision screenings are not diagnostic and can only identify some vision problems.
  • Most vision screenings cannot detect problems with: focusing, eye tracking, or depth perception.

A comprehensive eye exam should include tests to determine nearsightedness, farsightedness, astigmatism, eye coordination and eye muscle function, eye focusing abilities and visual processing.

What should teachers look for?

Here is a list of signs that a student in your classroom may be experiencing vision difficulties:

  • Blurry or double vision
  • Squints eyes
  • Reading below grade level
  • Difficulties with comprehension
