Squint [Strabismus] is a condition in which there is a misalign¬ment of the eyes. In other words, the two eyes are pointed in different directions. One eye may be looking straight ahead while the other is turned inward, outward, upward or downward. Muscles of the eye control movements of the eye. If one muscle is stronger than the other, the eye will be turned towards that direction. This is how a squint is formed. To treat this, one has to weaken the stronger muscle and strengthen the weaker muscle.
