  1. While blue light during daytime hours can promote attention, it can have the opposite effect at night. If you find yourself using devices that emit blue light at night time, such as your phone, you can disrupt your circadian rhythm. [2] Additionally, constant exposure to any kind of light can damage your eyes and cause problems with your vision.
    • To reduce eye strain from blue light, use dim or dark-colored lighting. Avoid using your phone about three hours before bed. Take constant eye breaks; look away from the screen for 20 seconds at least once every 20 minutes.
    • Using an app such as Screen Time can help limit your phone usage at night.
