Yes, lazy eye (amblyopia) can be treated in older children and adults, although the success of treatment may be less predictable and the outcomes may not be as good as when treatment is started at a young age.
The most common treatment for lazy eye is patching, which involves covering the stronger eye with a patch for several hours a day to force the brain to use the weaker eye. This treatment can be effective in improving vision in the weaker eye, even in older children and adults.
