The main eye diseases that can be found in children are refractive errors (such as myopia, astigmatism or hyperopia), congenital cataracts, amblyopia (lazy eye, which affects 4% of children) and strabismus. The first symptoms of ocular pathology in children can be, tendency to deflect an eye or both, inclination of the head to get a better fixation, problems to read the blackboard, etc. All these problems, if they re not treated in time, can lead to a child’s poor school performance.
