This refers to a misalignment of the eyes, whereby one eye turns either inwards or outwards. It is also commonly known as a ‘squint’. This interferes with one’s ability to achieve binocular vision (seeing with both eyes) hence affecting depth perception and causing lazy eye (amblyopia). It usually starts around infancy or early childhood. Some children may experience this because of an uncorrected long-sighted prescription, but other times its root cause is unknown.
The treatment for this condition varies, depending on its cause and the status of the visual system.
