About eye diseases Children's Eye Diseases There are many eye diseases that can affect a child's vision. Many of these conditions, if diagnosed early via a sight test, can be treated and vision can be restored. If the condition is not diagnosed until later in life, treatment will not be as effective. Common signs of vision troubles in children include frequently rubbing their eyes, squinting, tilting or turning the head to look at objects, wandering eyes, or squeezing eyes. If your child displays any of these symptoms, please arrange a sight test for them without delay. NHS sight tests are free of charge for children under the age of 16. It is important for your child to have regular sight tests, at least every two years. The most common conditions that can affect a child's vision include: Amblyopia (lazy eye), strabismus (crossed eyes) colour deficiency (colour blindness) refractive errors (nearsightedness, farsightedness, and astigmatism). National Eye Research Centre invests in research to help identify and treat a range of childhood eye diseases. Professor Irene Gottlob at the University of Leicester is aiming to use a novel approach to better predict infants with the highest risk of retinopathy of prematurity.
