Parents in the US are not taking their children to have their eyes tested in early life, which could lead to complications later on, according to the Western University of Health Sciences.
National Institutes of Health (NIH) latest research shows great headway in the treatment of convergence insufficiency (CI), a common childhood muscle coordination problem - and this highlights the need to get children"s eyesight tested regularly.
However, a recent survey by VSP Vision Care revealed 76 per cent of children under the age of five have never received a comprehensive eye exam.
Nearly seven per cent of US children under the age of 18 have a diagnosed eye condition.
Leaving conjunctivitis aside, the four most common conditions are refractive disorders, potentially blinding disorders, trauma or injury, said the university.
Symptoms of CI include loss of place, loss of concentration, reading slowly, eyestrain, headaches, blurry and double vision.
A visit to the optician will also reveal vision problems that can be easily corrected by prescribing glasses or contact lenses.
