Shock therapy for lazy eye? new trial tests brain zaps on kids

This study tests whether a non-invasive brain stimulation technique called tDCS can safely improve vision in children aged 4–14 with lazy eye (amblyopia) that hasn't improved with standard patching. One hundred kids will receive either real or fake tDCS sessions, and their vision will be measured before, during, and after treatment. The goal is to see if tDCS can boost visual acuity, depth perception, and contrast sensitivity better than a placebo.
