As summer winds down and students prepare to head back to school, many parents will be focusing on securing supplies necessary for the fall — from new outfits to notebooks, folders, and pencils.

However, according to the, it’s also important for your children to make a trip to the eye doctor, to ensure that they do not require corrective lenses.

The news soured reports that, because 80 percent of learning is visual, it’s imperative that students are able to see clearly in class.

Those who are nearsighted could have difficulty reading the chalkboard, and kids who are hyperopic might have trouble with worksheets and text books. Vision impairment could also make sports more difficult, the American Optometric Association (AOA) reports.

In order to learn effectively, the organization suggests that students have their visual acuity, eye focusing, eye tracking, eye teaming, eye-hand coordination and visual perception tested.

The AOA recommends that school-aged children visit their eye doctor regularly, as their vision is very likely to change as they grow. It is also recommended that infants first be taken to visit an eye care professional for an evaluation when they are 6 months old.
