Adjunctive Bright Light Therapy for Opioid Use Disorder

Light treatment glasses (Re-timer®) will be used to deliver bright light therapy. This device is available commercially and allows participants to freely move around while receiving light from LEDs positioned below the eyes. Re-timer® can be worn over glasses and does not interfere with vision, reading, or computer work.

The placebo Re-timer® emits light intensity to a level that will not impact sleep and circadian timing and appears identical to the original Re-timer®.
