Amblyopia, or lazy eye, can cause poor vision because one eye is weaker than the other. The problem has been thought to be untreatable in adulthood because it's believed to be caused by poor processing in the brain.
A study in Current Biology found 15 minutes of transcranial magnetic stimulation, or TMS, improved the sensitivity of the weaker eye temporarily . Now, researchers want to try a more involved test to see if multiple bouts of TMS can produce longer term results.
