Visible light is much more complex than you might think.

Screen time before bed can mess with your sleep. People with technology sleep less than they did a generation ago. The decline is largely attributed to artificial light before bedtime destroying  our ability to stay in sync with the 24-hour day.

Most people are aware that sunlight contains visible light rays and also invisible ultra-violet light rays that can tan or burn the skin. But what many don't know is that the visible light emitted by the sun comprises a range of different-colored light rays that contain different amounts of energy.

Here are some eye-opening facts about blue light:

• More blue light is emitted from smart phones and tablet computers than from any other light source.
• The average American adult spends more than 11 hours per day on electronic devices.
• Teens spend an average of 9 hours a day in front of a variety of screen types, including TVs, cell phones, computers and tablets. Tweens clock in at around 6 hours of screen time.
•  71% of Americans say they haven’t discussed their digital device usage with their eye care provider. Many are unaware of steps they can take to combat digital eye strain.
• 50% of eye doctors report an increase in digital eye strain and effects from blue light exposure among patients.
• Lutein and zeaxanthin are the only two carotenoids your body selects for protection in the eyes, but your body doesn’t make them naturally.
