A child isn't always manifesting his usual troubles, so it is really necessary to go regularly to an ophtalmologist to do control visits.

Daily observations:

• Your child is screwing up his eyes to see in the distance or maybe he's got a real tendancy to be too close to his books or to the TV ?

• Do you to screw up yours eyes to watch roadsigns ? Or not to be able to recognise in the distance the faces of the people you know ?
