This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
After heart surgery, your body can experience harmful inflammation during recovery. This study tests whether wearing special goggles that block blue light at night—similar to how our bodies naturally rest in darkness—can reduce that inflammation and help you heal better. Researchers will compare how well patients recover when wearing blue-light blocking goggles versus regular clear goggles at night while in the hospital.
Hospital environments keep lights on around the clock, and research suggests that nighttime light exposure may trigger excessive inflammation in patients recovering from major surgery. This study aims to see if reducing blue light at night—the type of light most likely to disrupt your body's natural healing rhythms—can improve your recovery and quality of life after heart surgery.

If you join this study, you will be randomly assigned to wear either blue-light blocking goggles or regular clear goggles each night while you recover in the hospital after your heart surgery. You'll wear the goggles during nighttime hours as part of your normal hospital stay. The research team will monitor your recovery, measure inflammation markers in your blood, and track how well you heal—all as part of standard post-surgery care. The study involves about 80 patients total across both goggle types.
