Causes Lazy Eye (Amblyopia)
Lazy eye or amblyopia is a condition where the eye can not achieve normal visual acuity, even with glasses or contact lenses. This eye disorder is a condition in which the eyes have abnormal deviations of the location of one eye to the other eye, so that the line of vision to be not parallel and at the same time both eyes are not focused on the same thing.

Decrease in visual function is due to a failure of vision stimulation or not strong enough stimulation transmitted from the optic nerve to the brain in a certain period. This can happen even in eyes with normal structure. Often occurs in one eye, although in some circumstances can occur in both eyes, many people especially with mild amblyopia was not aware of his condition until adulthood and eyesight test carried out.

Lazy eye or amblyopia is one of the eye problems that occur during the growth of the child. In children who have a lazy eye, the quality in view of the right eye and the left are not the same. Usually one eye will be weaker than the other eye or distorted.

Lazy eye occurs when the nerve pathways between the brain and the eye is not stimulated properly. This can lead to a condition in which the brain stimulates only one eye, usually because of weak vision in the other eye.

Over time, the brain learns to ignore the image sent by the weak eye and can only accept images from a strong currency. So that the weak eye will never learn to see. This condition usually develops before a child is 6 years old.

The common causes include their nearsightedness or farsightedness, crossed eyes, or obstructs the view, for example eyelid down and cataracts in children. Lazy eye usually only affect one eye only, ta [i if both eyes do not get a good visual stimuli over a long enough period, then the condition can occur in both eyes.

Kids have a higher risk if

- Injury to the eye
- The difference in size between the eye glasses with each other
- Astigmatism great, nearsightedness (myopia) or farsightedness (hyperopia)
- Strabismus or squint which the eyes are not aligned unused
- Visual impairment due to birth defects such as drooping eyelids (ptosis), cataracts

Early diagnosis would improve therapeutic success, because after the age of 8 years, potentially permanent visual impairment. Conversely, if a child does not experience amblyopia until he was over 8 years, there is little likelihood he will experience it.

Amblyopia if neglected and not immediately given treatment could cause permanent visual impairment. This is because the brain will gradually ignore signals being given eye refraction.

Treatment of amblyopia can be done by wearing corrective glasses, eye patches, or in severe cases, surgery.
