How to Protect Yourself Against Blue Light Eye Damage

If you're spending 8 to 10 hours a day in front of the screens of your computers and smart devices, you could be experiencing an overload of something called "blue light" If you're exposed to too much of this light, it can cause things like disrupting your sleep patterns, retinal cell damage, and digital eyestrain. What's worse, is that younger eyes are more at risk. Your tech devices play a big role in your life, so it's unrealistic to give the advice that you stop using them. There are a number of things you can do to reduce the amount of blue light you're exposed to. Check out these quick and easy tech tips to help you cut down how much blue light your devices emit.

1. Enable Blue Light Protection On Your Devices. Hardware and software manufacturers are aware blue light can cause issues, so most of your smart devices already have a means for you to enable protection.

  • iPad or iPhone: On your iPhone or iPad, go to Settings > Display & Brightness. Tap the Night Shift setting, which will change the screen temperature of your Apple device to a warmer color, which will filter out the blue light. This won't permanently change your devices to filter blue light. It's designed to filter out blue light to help your body adjust to sleep, so you will have to enable it every time you use your device.

  • Andriod Smartphone or Tablet: Most Android devices have built-in blue light filters, but not all. If your mode supports this, go to Settings > Display. Look for an option for Night Light or Blue Light filter and turn it on. Like Apple devices, this doesn't enable blue light permanently, you have to turn it on every time you use your device.

  • Windows 10: I'm sure most of you think Windows devices are behind the curve, but they have blue light settings that can be turned on from Settings > System > Display. Toggle the Night light switch to turn on the feature. Like other devices, you have to enable this every time you use your Windows computer.

  • Apple Computer: If you have an Apple computer 2012 or newer, you can turn on the blue light blocking feature. To do so, follow these steps: Choose Apple menu> System Preferences> Click Displays >Night Shift tab. Again, this will only allow you to set a schedule to turn this feature on. It does not enable it permanently.

2. Download an App. If you own an Android device that doesn't have a blue light filter, consider the following apps>

  • sfilter. This app will allow you to turn it on and off at specific times. You can change the color and brightness of the filter, and even create a shortcut icon or widget, so you don't have to open the app to enable the filter.

  • Blue Light Filter. This app will allow you to adjust the color temperature by choosing from among several options as well as tweaking the intensity and the brightness of the filter.

  • Twilight: This app will allow you to always enable the filter to run from sunrise to sunset, or turn on and off at specific times.

3.Get a screen protector. No matter what device you spend hours staring at, you can get a screen protector to help block blue light. Check out products from You can get screen protectors for Apple, Samsung and a variety of monitors to help reduce the strain to your eyes.

4. Try Protection Glasses. new monitors and screen protectors aren't an option, try these blue-light-blocking glasses. Wear them while you're on your devices before bed to get better sleep at night. These glasses come with a protective case so you can take them to work, school or just keep them safe at home. Wherever you choose to wear them, it's nice to know you can protect your eyes any time, anywhere.

5. Rest Your Eyes. The simplest way to help prevent overexposure to digital blue light is by managing the time spent using them. Be sure to take regular breaks away from the screen. One easy method is to employ the 20-20-20 rule. Every 20 minutes, take a break from your computer to look at something 20 feet away for a minimum of 20 seconds. This technique can help you avoid eye strain, and serves as a regular reminder to be conscious of blue light exposure.

As you can see, there are many ways to protect your eyes from Blue Light. In our digital world, there is a need for laptops, television, and smartphone eye protection. Hopefully, the above advice will help you protect your eyes from a mobile screen or computer.
