Symptoms of Learning-Related Vision Problems

Visual efficiency depends on the ability to comfortably sustain normal vision for long periods of time.


Visual efficiency skills form the input channel for visual information as it travels to our brain to be processed and used for effective reading, writing and other academic tasks. Visual efficiency depends on the ability to comfortably sustain normal vision for long periods of time, especially at close distances where reading takes place. These skills allow us to see clearly, focus easily, use both eyes together, and track with our eyes.

We expect children to be able to read comfortably for extended periods of time, which increases as they get older. Even children in 1st grade are using their eyes at close distances in school for up to 4 hours a day.

Visual efficiency problems can interfere with higher level visual processing in the brain, as well as reduce reading speed, fluency and comprehension. The longer a child with visual efficiency problems reads, the harder it gets, often resulting in difficulty sustaining attention in the classroom and during homework.
