Amblyopia, the medical term for lazy eye, occurs when the vision in one eye fails to develop during childhood, usually before the age of six. Lazy eye often involves significant differences in the sight of the two eyes and it often occurs with strabismus, the condition known as cross-eyes, according to the American Optometric Association. Lazy eye does not affect side vision and is not related to the health of the eye. People with lazy eye tend to favor one eye and they may have a general clumsiness that causes them to bump into things on one side of their bodies (See Ref 1).

Some Causes Amblyopia

• Crossed eyes

• Eyeglasses- where one lens has a higher prescription than the other lens – is at rick.

• Depth perception – 3 dimensional vision, and cataracts.

• Any eye disease that blocks the visual images from reaching the back surface of the retina.


Childhood lazy eye is usually treated successfully when diagnosed early. Medication and patches force the weak eye to work harder (Ref 2). Other treatment tools and methods include prisms, prescription lenses and vision therapy, which retrains both eyes and the brain to work together. Lazy eye does not disappear or improve without treatment. Health care professionals believed that treatment for lazy eye after the age of six, especially during the teen years, takes more time, is less effective and might be of little benefit (See Ref 1). In 2010, the National Eye Institute reported that recent studies show promise for the treatment of lazy eye in older children, ages seven through 17 years old and research continues into effective treatment for adults with lazy eye (Ref 2) -.Left untreated, lazy eye can cause permanent vision loss. In fact, lazy eye is the most common cause of single-eye vision impairment in young and middle-aged adults, according to the National Eye Institute

Ambylopia is hereditary or genetic. As a preventative measure, all children under the age of 4 years should have a complete vision text. Up until the age of 9 years, when vision is completely developed,  it is possible to correct the problem - early detection is vitally important.
