Lazy eye responds best in childhood, and the earlier it is found the shorter treatment usually is. Here is how it is treated step by step, what each option asks of your child, and a way to see which options fit.
Lazy eye in children is treated in steps. Full-time glasses come first and improve the weaker eye on their own in many children. If a gap remains, the stronger eye is patched for a set number of hours a day or blurred with atropine drops, and binocular therapy trains both eyes to work together. A squint may need its own treatment, but surgery does not fix the vision.
Four quick picks. The list re-orders to show what usually suits a child like yours.

General guidance from published research. What suits your child or you is confirmed at an assessment.
1. Glasses first. Many lazy eyes are caused by a focusing difference between the two eyes. Wearing the right glasses all day lets the weaker eye start to catch up, and in many children vision keeps improving for four months or more on glasses alone.
2. Make the weaker eye work. If a gap remains, the stronger eye is covered with an eye patch for a set time each day, or blurred with atropine drops. For moderate lazy eye, two hours of patching a day works as well as six.
3. Teach the eyes to team. Binocular and dichoptic therapy uses games and activities in which each eye sees something different, so the brain stops switching the weaker eye off. It also trains depth perception, which patching does not.
4. Hold the gains. Treatment is tapered rather than stopped. Roughly one child in four loses some vision in the first year when treatment ends abruptly.
Choose the line the weaker eye can read. Then switch views to see suppression, and what the world looks like with a patch on.

With each eye tested on its own, the gap between them is what defines a lazy eye.
An illustration of blur and suppression, not a vision test. Only an eye examination can measure each eye.
The visual brain is at its most adaptable in the first seven years, so a lazy eye found at three or four usually needs less treatment, for less time, than one found at ten. Lazy eye rarely shows from the outside, which is why so many are picked up only at a school screening. For a baby or toddler, start with signs of lazy eye in babies; for school-age children, see the signs of lazy eye in children.
Older children still respond. Children aged 7 to 12 who have not been treated before often gain several lines, and teenagers can improve too. Our guide to the lazy eye treatment age limit sets out what changes at each age.
Glasses on, patching done, and the weaker eye still behind? An assessment checks for suppression and what is holding it back.
See how adaptable the visual brain usually is at that age, and what treatment usually involves.
The curve is a simplified illustration of published findings. Individual results vary with the cause, the severity and earlier treatment.
Treatment works only if it is done, and for most families the daily routine is the hardest part. What helps:
A lazy eye assessment measures the vision in each eye, checks for a squint and for suppression, and sets out a written plan. In clinic in Chennai and Hyderabad, with online consultations across India.
