Blue Light Filter Setting On Computer

[Doris Joo]

When you turn on most digital devices, their screens vibrantly illuminate so that you can see easily in a variety of light settings. However, the visible light that comes from your screen is more complex than you might think.

The simplest blue light definition is a high-intensity, short wavelength range of visible light on the spectrum. Blue light is a high-energy, visible (HEV) light; falling in the same category of visible light as violet.

Darker colors like violet and blue are the closest to UV wavelength and strength. Lighter colors like red and yellow are on the opposite end of the spectrum with longer wavelengths and lower energy levels.

Blue light is harmful the same way having too much sodium in our diet is harmful. Our bodies are naturally adept at absorbing and dealing with blue light exposure, but like anything else, too much can be detrimental.

Digital eye strain, also known as computer vision syndrome, may lead to dry, sore, red eyes and blurred vision. With enough prolonged exposure, blue light can harm your eyes and lead to macular degeneration - causing damage the same way UV rays would.

The same study also found that green light may be damaging and strenuous on the eyes as well. The typical wavelength of blue light falls between 450 and 490 nanometers. The wavelength for green light is 520 to 560 nanometers, with cyan falling in between.

Take time to rest your eyes every 20 minutes or so. Look away from the computer and focus on something distant - like a poster on the wall across the room or out a window. Close your eyes gently, then squeeze and hold them shut for a moment, then open and relax them. Try to remember to blink more often in between, too, and when you are thinking, instead of squinting at the screen, turn away and blink a few times. Your eyes will thank you.

One of the most popular blue light filter applications is F.lux. Like most blue light filter applications, F.lux reduces the blue light coming from your screen and boosts the warmer colors like red, yellow, and orange. One of the unique features that makes F.lux stand out from the other applications is the ability to adjust your settings to the time of day. Rather than setting timers and remembering to activate the filter on your PC or device, F.lux will automatically change in accordance to the ambient light throughout the day.

Another great application is Iris. Iris is one of the most intuitive and user-friendly blue light filter applications. With Iris, you can choose from a variety of modes and types within the settings menu. Select from options like automatic, manual, and paused mode for your convenience and preference.

Within the type settings, you can select health, reading, programming, biohacker, sunglasses, dark, movie, and overlay. Each of these options gives the user a slightly different experience and changes the display setting to accommodate specific tasks or activities.

If you were to do a side-by-side comparison of blue light filter applications and physical blue light blockers like glasses, it would quickly become apparent that the physical barrier diminishes the quality of the picture and color far less than its application-based counterpart.

Physical blue light filters are the easiest and best way to reduce your blue light exposure. Some blue light filters for PCs are just a clear piece of plastic material that covers your monitor, while other filters come in the form of blue light blocking glasses.

If you have to work late at night on a PC or cell phone, wearing blue light filtering glasses for 3 to 4 hours before bedtime is the easiest way to keep your melatonin levels in check [3] and your retinas protected. While some of the flashier glasses may cost upwards of $80, you can get inexpensive pairs for $10 to $20 online.

The downside of physical blue light filters is that they are rarely made of durable material and you may end up having to replace them from time to time. Additionally, many prescription and over-the-counter reading glasses come with blue light filters in the lenses, so it may be a waste of time and money to invest in a blue light filter if you regularly wear prescription glasses.

From here, you can adjust the levels of blue light reduction and the timeframe you would like to restrict and control them. You may also choose to automatically adjust the brightness when the lighting changes.

The reason blue light hurts is purely biological. Sleep is a part of the circadian rhythm, which is the cycle of biological processes that are determined in part by the levels of light and dark exposed to our bodies.

Microsoft added a blue light-limiting feature to Windows 10 in the Creators Update released in April 2017. Called Night Light, this feature shifts the Windows 10 and 11 display to show warmer colors that reduce the amount of emitted blue light. Turning the feature on is a simple process.

Step 3: On Windows 10, the Display category opens by default. In Windows 11, you'll need to select it from the list of categories on the right. Scroll down on the right and toggle on the Night Light setting. In Windows 11, you'll find the setting in the Brightness & color section.

Step 1: Click the Apple logo in the top-left corner and select System Preferences on the drop-down menu. Alternatively, click the System Preferences icon on the Dock. In macOS Ventura and later, the utility is called System Settings.

Here, you can configure when Night Shift automatically runs, turn it on until the next sunrise, and set your preferred color temperature. For scheduling, you can let macOS turn it on and off at sunset and sunrise based on your location, or you can set a custom schedule.

Step 4: Click on the toggle located to the right of Night Light to enable this feature. On macOS Ventura and later, click on Night Shift... at the bottom of the window to open the settings.

Both Macs and PCs have built-in blue locking blocking modes. On a Mac, you can enable blue light blocking by turning on Night Shift, located in the Displays section of System Preferences. On a PC, blue light blocking is called Night Light, and it's located in Display (Windows 10) or Brightness & Color (Windows 11).

Yes, most Windows and Mac computers have blue light filter settings that work brilliantly to block unwanted, circadian rhythm-disrupting lights. On a Mac, it's called Night Shift, and on a Windows computer, it's called Night Light. In addition, there a handful of third-party apps you can download to block blue light on your computer, like F.lux.

VPNs can offer a lot of great advantages depending on what sort of things you want to do. For example, if you're traveling and still want to watch content from back home, they can offer you a way to get around geoblocking that tends to happen. Alternatively, they can help protect you against man-in-the-middle attacks that aim for your identity information, such as online passwords or even credit card numbers, which is especially an issue if you tend to connect to public Wi-Fi networks. While they aren't perfect security tools, they're a great addition to make your life easier, especially since some of the best VPNs include a whole suite of products, including ad blockers.

VPNs are premium subscription services though, meaning they're not free (well, some are, but you probably shouldn't use them). VPN deals can cut some cash off the price tag, but there's only one way to get one absolutely free -- free trials. NordVPN is one of the best VPN services, so the NordVPN free trial is very popular. It's great for security, and it's the best VPN for Netflix. Read on to learn how you can take advantage of the NordVPN free trial.

Most web-connected devices have the convenient ability to remember Wi-Fi networks you connect to everyday, along with networks you only link to on occasion. Macs and MacBooks are no exception to this rule, but what do you do if you own one a macOS machine and want it to forget a Wi-Fi network? Simple: Manually remove it from your computer altogether.

For most new Mac users -- especially if they're coming from Windows -- one of the first questions they need to ask is how to take a screenshot on a Mac? There's no dedicated Print Screen key like there is on Windows, but there is keyboard shortcut, and if you want something more akin to Microsoft's Windows Snipping tool, there are some great screenshot apps you can use, too.

Here's how to take a screenshot on a Mac in a few different ways.
How to take a screenshot using keyboard shortcuts
MacOS keyboard shortcuts are the quickest ways to take screenshots, whether you're capturing the entire screen or just a portion. By default, Apple's methods save your screenshot to the desktop, but if you want to copy the screenshot to the clipboard, there's a keyboard shortcut you can use instead.
