How to identify our son/daughter has a lazy eye problem? What are the most obvious signs? What is the best treatment? These are some of the questions that we will try to answer to understand a little better what exactly the lazy eye is.
The child with lazy eye experiences a decrease in unilateral vision. Visual defect that affects only one eye. In practice, the two eyes are not used simultaneously and with the same intensity. In other words, it is as if the child chooses to exploit the potential of one eye forgetting the other.
The symptoms or signs to consider and that can make us suspect the problem is the presence of one eye larger than the other; discomfort towards light; a deviation of one eye; the child’s need to be often objects very close to the eyes; child habit of bending his head while reading, to draw or watch TV.
