Blue Light – Did You Know?

Blue Light – Did You Know? 

Many of us spend a good chunk of the day glued to a screen. Last year, a Nielsen Company audience report revealed that the average adult in the United States spends 8 hours and 47 minutes a day on a device. Which begs the question: How is all that screen time affecting our eye health and more?

The answer isn’t so clear. Some doctors worry that exposure to blue light from electronic devices may have a negative impact on our eyes. “Blue light is concerning because the cornea and the lens don’t filter it out, so it goes right to the back of the eye,” says Anam Qureshi, MD, clinical assistant professor of ophthalmology at NYU Langone in New York City. She says some experts think it might damage the retina and lead to conditions like macular degeneration—though there isn’t any research to back up those concerns.

How to Protect Your Eyes
There are many ways to protect your eyes and we recommend seeking medical advice from your eye doctor. However, if you have an Apple smart device with IOS 9 or above, you can turn on Night Shift – a feature that automatically change the color or the screen into a warmer shade. Please follow the steps below to turn this feature on:

Make sure you are using a compatible Apple Device. Devices compatible with Night Shift are:[3]
iPhone 7 and 7 Plus
iPhone SE
iPhone 6s and 6s Plus
iPhone 6 and 6 Plus
iPhones 5s
iPad Pro
iPad Air 2
iPad Air
iPad Mini 4
iPad Mini 3
iPad Mini 2
iPod Touch 6th Generation

Update your device to iOS 9.3 or newer. Apple introduced the feature in iOS 9.3. This means that you’ll need to be running that version or a newer one to activate Night Shift.

Look for and tap the gray gear icon with the word “Settings” right below. It’s located on your home screen, usually in the first page. Press the Home button at the bottom of your device and then swipe left and/or right to switch home screens.

Tap on the Display & Brightness section. On iPads, this will be pushed to the left side of the screen.

Select Night Shift.

Set up Night Shift. Here’s what you can do:
Schedule Night Shift from sunset to sunrise so you don’t have to worry about any time changes. You must have location services enabled to do this.
Manually enable night shift until the next sunrise (or a specific time to turn off if you’ve configured it).

Set the warmth of your screen. The warmer you set your screen, the less blue light will be emitted from the display and the better your sleep will be.
