This is a tendency for the eyes to drift inwards (cross eyed).  Many people are born with a tendency for the eyes to turn inwards but they build strong eye muscles in youth to offset this. With age, these muscles may weaken and the eyes may turn inwards again, causing intermittent or constant double vision. When the eyes consistently remain misaligned, this is then called an esotropia.
