Explanation

Strabismus, also called squint, is a problem with your eyes in which they are not looking in the same direction. You might also hear it called lazy eye. One of your eyes will be turned inwards or outwards or up or down, while the other one is looking straight ahead.

This happens either because your brain has a problem in getting your eyes to work together, or because one or more of the muscles that tell your eyes where to look aren't working properly, so both your eyes don't look at the same point.
