Amblyopia, commonly known as lazy eye, is a vision disorder that occurs when one eye does not develop normal visual acuity, even with the use of corrective lenses. It is most commonly seen in children but can persist into adulthood if left untreated.

Amblyopia often arises from conditions that hinder clear vision in one eye, such as strabismus (misalignment of the eyes), significant refractive errors (nearsightedness, farsightedness, or astigmatism), or structural abnormalities. The brain tends to favor the stronger eye, leading to decreased visual stimulation and development of the weaker eye.


If you have Amblyopia, you may observe


Reduced Vision


Poor Depth Perception


Squinting or Shutting One Eye


Struggling with Visual Tasks

Vision screenings using adequate testing equipment ?

If left untreated, amblyopia can result in permanent visual impairment in the affected eye. Early diagnosis is crucial, typically through comprehensive eye examinations in childhood. Treatment aims to stimulate and strengthen the weaker eye by patching or blurring the stronger eye, encouraging the brain to rely on the amblyopic eye.

Treatments for Amblyopia

Corrective eyewear Glasses or contact lenses can correct problems such as nearsightedness, farsightedness or astigmatism that result in lazy eye.

Eye patches. To stimulate the weaker eye, your child wears an eye patch over the eye with better vision for two to six or more hours a day. In rare cases, wearing an eye patch too long can cause amblyopia to develop in the patched eye. However it's usually reversible.

Bangerter filter. This special filter is placed on the eyeglass lens of the stronger eye. The filter blurs the stronger eye and, like an eye patch, works to stimulate the weaker eye.

Eyedrops.An eyedrop of a medication called atropine (Isopto Atropine) can temporarily blur vision in the stronger eye. Usually prescribed for use on weekends or daily, use of the drops encourages your child to use the weaker eye, and offers an alternative to a patch. Side effects include sensitivity to light and eye irritation.

Surgery.Your child might need surgery if he or she has droopy eyelids or cataracts that cause deprivation amblyopia. If your child's eyes continue to cross or wander apart with the appropriate glasses, your doctor might recommend surgical repair to straighten the eyes, in addition to other lazy eye treatments.

Amblyopia is a vision disorder in which one eye has reduced visual acuity, often referred to as lazy eye.

Amblyopia can be caused by factors such as strabismus (eye misalignment), significant differences in refractive errors between the eyes, or conditions that obstruct clear vision during early childhood, like cataracts or ptosis.

Symptoms of amblyopia include reduced vision in one eye, poor depth perception, and squinting or misalignment of the eyes.

While amblyopia is most effectively treated in childhood, vision improvement can still be achieved in some adults through vision therapy, specialized contact lenses, or other treatment options. .

With early intervention and appropriate treatment, amblyopia can be improved, but if left untreated for a long time, the visual impairment may become more difficult to correct fully. .
