We are constantly looking at screens these days. Whether it’s for work, for pleasure, or to keep up with what’s going on in the world, screens have become a big part of our lives. And while they have many benefits, they also come with some drawbacks. One of the biggest is the blue light that they emit.

Exposure to blue light can have some negative consequences. It can cause digital eye strain, which leads to dry eyes, headaches, and even migraines. It can also disrupt our sleep patterns, making it harder to fall asleep and stay asleep. And since we are looking at screens more than ever, we are being exposed to blue light for longer periods of time, which can magnify these effects.

So what can we do about it? One option is to use blue light filters. These filters can be built into our devices or they can be external. Apple has a built-in blue light filter on all iPhones and iPads running iOS 9.3 or later. To turn it on, go to Settings > Display & Brightness > Night Shift. Here you can schedule when you want the filter to turn on and off, or you can set it to come on automatically at sunset and turn off at sunrise.

When Night Shift is on, your device will have a warmer color temperature, which will reduce the blue light emitted by the display. This can help you sleep better and feel more comfortable looking at your screen.

There are also a number of apps that you can download that will filter blue light. f.lux is one of the most popular, and it’s available for iPhone, iPad, and iPod touch. It’s free to download and use, and it doesn’t require a jailbreak.

To use f.lux, open the app and set your location. Then choose the type of screen you are using and how bright it is. You can also set a schedule for when you want the filter to turn on and off. Once you’ve done that, f.lux will start filtering the blue light from your device’s display.

If you don’t want to use an app, there are some other ways to filter blue light. One is to wear blue light filtering glasses. These glasses have a special coating that absorbs blue light, and they can help reduce digital eye strain and improve sleep.

There are also blue light filtering screens that you can attach to your device. These work in a similar way to the glasses, and they can help reduce the amount of blue light that you’re exposed to.

So if you’re looking for ways to reduce the amount of blue light you’re exposed to, there are a few different options. You can use Night Shift on your iPhone or iPad, or you can download an app like f.lux. You can also wear blue light filtering glasses or attach a blue light filtering screen to your device.
