Amblyopia, commonly known as “lazy eye,” is a condition in which one eye has reduced vision that cannot be fully corrected with glasses or contact lenses alone. It is one of the most common vision problems in children and occurs when the brain fails to develop normal vision in one eye during early childhood.
What causes amblyopia?
Amblyopia is often caused by strabismus, also known as a crossed or turned eye, which occurs when the eyes do not point in the same direction. When the eyes are not properly aligned, the brain receives two different images and learns to ignore the one from the weaker eye, leading to amblyopia.
Amblyopia can also be caused by anything that blocks or blurs vision in one eye, such as a drooping eyelid or a cataract. Another common cause is a significant difference between the two eyes in the amount of farsightedness, nearsightedness, or astigmatism. To learn more about these focusing problems, see our article on refractive errors.
Why early detection matters
Amblyopia can be prevented if its onset is caught and treated in time. The best time for an eye exam is between 6 months and 3 years of age, when a child is most at risk of developing amblyopia if the underlying problem is not treated. Prompt treatment is crucial when an eye turn or a significant difference in prescription between the two eyes is present.

How amblyopia is treated
Treatment works by encouraging the brain to use the weaker eye so that it can develop better vision. The most common approaches include:
- Patching: the stronger eye is covered with an adhesive patch for a set period each day so that the “lazy” eye is forced to work and strengthen.
- Atropine drops: drops are used to temporarily blur the vision in the stronger eye, encouraging the brain to rely on the weaker eye. Patching and atropine drops are sometimes used together.
- Vision therapy: a program of exercises designed to improve visual skills, which can be combined with patching or atropine drops.
A combination of these methods sometimes produces the best results, and your ophthalmologist will recommend the approach that is most appropriate for your child.
The takeaway
Amblyopia is a common vision problem that, when caught and treated early, can be prevented. The key is early detection through routine eye exams, especially for children. Patching, atropine drops, and vision therapy are all effective treatment options. Left untreated, however, amblyopia is a serious condition that can cause permanent, irreversible vision loss in the affected eye.
