This study aimed to quantify glare induced into the NICU through phototherapy devices commonly used to treat neonatal jaundice. The blue light associated with the devices can cause a number of physiological affects including melatonin suppression, disturbances of one's circadian rhythm, and has the potential to lead to risk factors of age-related macular degeneration (AMD) in the long term. The study found that the phototherapy device tested emitted a sufficient amount of light to be considered 'disturbing' using the DeBoer scale. Due to this, phototherapy devices in the future should take into consideration the minimization of light emitted which is not directly treating the infant on the device to prevent potential physiological effects that nurses may experience.
