Researchers from the Ohio State University have found that preschoolers and kindergartners who are farsighted could be at risk of falling behind at school due to the condition affecting their concentration.

The children were tested to evaluate their attention, visual perception and the ability to integrate visual perception and motor skills. The results showed that the children who were moderately farsighted were significantly more likely to have poorer scores on the attention- related tests. Glasses aren't always recommended for this condition as some believe vision correction isn't the right option for children of this age.

The research team now plans to carry out a follow-up study to investigate if glasses could be an effective option to correct farsightedness in children.
