A squint which is also known as Strabismus or crossed eyes develops when the eye muscles do not work in a balanced way and the eye does not move together correctly. This loss of coordination between the muscles of the two eyes leads to misalignment. Under normal circumstances, eyes move in a parallel direction. But in case of the Strabismus disease, one eye points in the direction in which the individual is looking and the other eye can turn inwards, outwards, downwards or upwards. This condition is common in children than in adults.
The squinting eye is used less often and brain tends to neglect the image from that eye. In children, it may lead to Amblyopia. In addition, squint diminishes the development of in-depth perception which is required in activities like driving and sports. The disease squint does not correct on its own. Treatment should be done at earlier stages and the chances of improvement are also more.
In order to improve vision, the weakened muscles in the affected eye must be put to work. Several techniques may be used alone or also in combination, depending on type, severity, and cause of squint. It includes eyeglasses or contact lenses.
