Amblyopia, sometimes called “lazy eye,” is when vision in one eye does not develop properly during childhood. It is a common problem in babies and young children.

Amblyopia is treated by making the child use their weaker eye. This is done by putting a patch over the child’s stronger eye. Sometimes eye drops or special glasses may be used to blur vision in the stronger eye. Patching may be necessary for several weeks to several months for the weaker eye to strengthen. Sometimes a child may need to continue to wear an eye patch part-time for a few years. This is because there is a chance that eye can weaken again.
