Could light therapy glasses help fight opioid cravings?

This pilot study tested whether wearing bright light therapy glasses can improve sleep and reduce cravings in people being treated for opioid use disorder. Twenty-three adults on stable medication-assisted treatment (methadone or buprenorphine) with insomnia used either active or placebo light glasses for several weeks. The study focused on whether the treatment was feasible and acceptable, and looked for early signs of benefit on sleep, reward learning, and opioid craving.
