How much of your day do you spend in front of a digital screen? If you are like most people, between looking at your computer, phone, and tablet – most of your waking hours. Studies suggest 60% of people spend more than 6 hours a day in front of a digital screen. Why should you care? As you’ve probably seen in the news there have been more and more stories about blue light and its negative effects on our eyesight and overall health. While the studies are somewhat inconclusive they do agree that staring at blue screens can cause eye strain and disrupt our sleep.

What is Blue Light?
Blue light is a color of light on the visible spectrum that can be seen by the human eye. It is a form of light that is a short wavelength which means it produces a high amount of energy. This energy comes in natural and artificial forms. An example of natural blue light is the blue sky. This blue light is produced by the sun, and for a long time was the only source until modern technology came along. Natural blue light is needed for good health: It boosts alertness, helps memory, cognitive function and elevates moods. The short blue wavelengths help regulate our body’s circadian rhythm – the body’s natural wake and sleep cycle. In the modern era, sources of artificial blue light are in more places than ever. It is on the screens on our phones, TV’s, and other electronic devices. The increase in artificial blue light is what has people concerned.

What Can You do to Protect Your Eyes From Artificial Blue Light?

• Use a blue light filter on your digital devices. Some tablets and phones come with a feature built-in called a blue light shield or filter. If your device doesn’t have such a feature built-in then try downloading a blue light filter app.
• Limit your screen time before bed. Step away from your devices 2-3 hours before you go to bed. This will help your circadian rhythm.
• Use the Night Shift setting on your device. This setting automatically changes the colors of your display to the warmer end of the color spectrum after dark. You can schedule the shift, or you can manually change it.
• Follow the 20-20-20 Rule. Every 20 minutes shift your eyes to look at an object at least 20 feet away for 20 seconds.
• Use artificial tears. The drops can help soothe and refresh your eyes.
• Wear nonprescription computer glasses or your even your sunglasses. The darkened lenses can ease eye fatigue while working on your device.
