That might be fine if your problem is insomnia. To prevent eye strain, it is preferable to set f.lux/Iris to a lower CCT setting day and night.↑ Contents ↑DIY blue light filter app: Change screen colorsChanging text and especially background color is a free and easy DIY version of a (color transform) blue light filter app. Changing background and text color is a good option if you mostly read of the screen, edit text or work with spreadsheets.The advantage is that you can select any color you want and control the contrast level.Disadvantage: Not everything will appear as one would like to – particularly some buttons on web pages might be hidden or text on them invisible.Depending on your background/text color choice and digital screen model it may “filter” up to 75-95% of blue light as compared to black text on white background (estimates based on LEDMuseum and f.luxometer data).You may find detailed instructions on how to change background color and text color in:– Windows 7, Adobe Acrobat, Firefox, Chrome, Internet Explorer, etc… – Windows 10Choosing background color well is key to reducing blue light emissions of your digital screen; see Least likely colors to cause computer eye strain.Bluelight filter app & color changeYou can combine the two approaches, thus filtering blue light with the app and also being able to choose the colors your screen displays. Remember that the app will distort your colors, so if you care a lot about the exact colors displayed, you should set the app to

Microsoft has integrated and added a new feature in its April Update. It is called the night light. The function of the night light is basically to turn on the blue light filter on the Windows 10 and help improve sleep of users who use PC till late night. Almost all major operating system platforms have included the blue light filter in their ecosystems. What is this blue light filter? Computer or mobile screens have a bluish hue in their back light. After several years of exhaustive research, scientists from different parts of the world have found out that blue light disturbs sleep by hyper activating the eyes and the nervous system. This is one reason why why can not sleep even if we are tired. The blue light has been found to stimulate nerves and the brain simultaneously and deprives sleep. Since, health is the biggest priority of human life, every gadget manufacturing company have started using blue light filter software in their devices. When the blue light filter is turned on, a reddish hue filter is applied on the back light and the overall color warmth is increased to some extent. Blue light filters have been found to improve sleep to a good extent. You can turn on Night Light whenever you want. On the other hand, you can set automatic turning on off the night light. This is called scheduling of night light on Windows 10. In this tutorial, I shall show you how to adjust the color temperature of Night Light on Windows 10.1. First of all, click on the Start button and go to Settings.2. As Settings application opens, tap on System. System settings open all sub settings under it.3. In the left panel, you will find an option called Display. Click on it.4. In the right panel, you will find the Night Light option. Turn it on by tapping on the slider.5. Next, click on Night Light Settings. As the Settings open, you will find an option called “Color Temperature At Night. There is a continuous range of values which you can change by moving the slider. Choose the value with which you are comfortable.

Source: fluxometer.If supplementation appeals to you more than eating a bucket of green, leafy vegetables a day, see the article on best eye supplements containing all three macular pigment carotenoids – lutein, zeaxanthin, and meso-zeaxanthin. (If interested, see also a summary of my experience with macular pigment supplements).Note that the effect is not immediate – supplementation might show results in 8-12 weeks, and your MPOD might plateau in 6-12 months.Moreover, some people appear to be genetically pre-conditioned to lower MPOD or irregular macular pigment shape.↑ Contents ↑Software blue light “filtering” solutionsStrictly speaking, software solutions do not filter blue light. Instead, they reduce screen’s blue light emissions by altering the colors displayed by your digital screen. In most cases, the reduction of blue light cannot be 100%, because the software is restricted by the limitations imposed by the hardware.Color distortion depends on how much blue light you’ll want to take out. Colder colors – white, blue, green – are transformed into warmer, yellow-ish colors.Blue light filter appsPreserving contrast is a very important feature/advantage of a blue light filtering app because low contrast reduces readability thus causing computer eye strain.There are two different approaches used by blue light filtering apps: Color transform approach is superior because the alternative, transparent overlay, reduces contrast far more.You may easily recognize which approach an app is using by looking at what it does to black. Color transform leaves it unchanged because black has the lowest possible blue light content. Overlay approach, on the other hand, makes black look lighter (usually yellowish or reddish) thus reducing the contrast between black and other colors unnecessarily.There are two blue light filter apps that use color transform approach:– f.lux – free; designed principally to help with blue light induced insomnia; for Windows, Mac, Linux, and iPhone/iPad and Android– Iris (commission link) – freemium; designed to prevent computer eye strain and insomnia; for Windows, Mac, and Linux (Iris for Android uses transparent overlay approach due to system’s limitations).Essentially they both do the same thing – i.e. reduce the amount of blue light emitted by your screen. Therefore they may both be used for both eye strain and insomnia. However, there are some differences such that if your principal goal is to avoid computer eye strain you might find Iris more suitable. In terms of preventing insomnia they are very similar (for a full review see Best blue light filter apps for visual comfort: Iris & f.lux).Spectral power distribution (SPD) of screen emissions at different f.lux settings are available at fluxometer.com. SPDs in the case of Iris are similar for the same CCT settings.For example reductions in blue light emissions running

Way colors appear on the screen. Additionally, excessive reliance on these filters may lead to using screens for longer without taking necessary breaks. Experts like Dr. H. William (2021) caution that filtering blue light does not eliminate eye strain completely; proper screen habits, like taking breaks and blinking frequently, are still essential.To effectively reduce blue light exposure, users can implement several strategies. Firstly, utilize your device’s built-in night mode settings during evening hours. Secondly, consider applying a quality blue light filtering screen protector. Lastly, adopt the 20-20-20 rule: take a 20-second break to look at something 20 feet away every 20 minutes of screen time. Each of these strategies can enhance comfort and reduce the negative effects of blue light without draining your battery. What Technologies or Apps Can Help Minimize Blue Light Without High Energy Use? Technologies and applications exist to minimize blue light exposure without consuming high energy. These solutions include software settings, screen adaptors, and particular devices that help reduce blue light emissions.Software-based solutions Blue light filter apps Hardware options Specific device settings Wearable technology Transitioning from these solutions, it is essential to explore each category to understand how they minimize blue light exposure while being energy efficient.Software-based Solutions: Software-based solutions include built-in settings on devices that adjust screen color temperatures. Many operating systems, such as Windows and macOS, offer night mode features. These features reduce blue light emission by changing display colors to warmer tones, especially in the evening. According to a study by the University of California, this approach significantly reduces eye strain without demanding extra energy.Blue Light Filter Apps: Blue light filter apps adjust the color temperature of screens on various devices. Applications like Twilight and f.lux modify screen colors based on the time of day. They automatically apply warmer colors during evening hours, helping to reduce exposure to harmful blue light. A 2019 study by Chen et al. found that using such apps can lead to better sleep quality and less eye discomfort without substantial battery drain.Hardware Options: Hardware options include blue light blocking screen protectors or filters. These are physical attachments that can be placed over screens. Devices like the Pivos Blue Light Blocking Clip-on Filter can reduce glare and filter blue light effectively while consuming no additional energy. Research by the International Journal of Ophthalmology highlights that using such hardware helps improve visual comfort without affecting device performance.Specific Device Settings: Many modern devices offer specific settings for blue light reduction. For instance, smartphones and tablets often come with dedicated options like “Night Shift” (iOS) or “Night Light” (Android). These features lower blue light emissions without requiring additional energy consumption, as noted in a report by the American Academy of Ophthalmology.Wearable Technology: Wearable technology, such as smart glasses that filter blue light, can also reduce exposure. These devices are designed to block blue light while being lightweight and energy-efficient. A 2021 study published in the Journal of Vision indicated that wearing blue light blocking glasses during screen time mitigated eye strain and

Better solution? Maybe, but it is important to keep in mind that it is more accurate to say that these glasses filter blue light, and that the amount of blue light that is filtered can differ depending on the tint.Another option for blue light filtering? Photochromic lenses help you adjust to light indoors and outdoors, protect you from the sun’s damaging UV rays and filter some of the blue light from all those screens.So what should you do?When you’re outside working on your laptop on the patio or a balcony, your sunglasses can help filter blue light rays. But when you’re inside playing Fortnite, looking for jobs online, reading a favorite book or spending hours working on a big presentation for work, blue light glasses or computer glasses are a better way to ensure comfort while using digital devices.And if you want three-in-one filtering (UV, blue light and bothersome light) all in one pair of glasses (no need for eyeglasses and those easy-to-lose sunglasses), photochromic lenses are worth a look.WHAT ARE THE BEST BLUE LIGHT GLASSES FOR YOU? Research your options and shop for eyewear at an optical shop near you or at an online eyewear retailer. Blue light glasses typically filter higher energy blue-violet light, with wavelengths from 400 nm to 455 nm, not lower energy blue-turquoise light (465-495 nm). Not all products that claim to filter blue light will filter both blue-violet light and blue-turquoise light. Ensure your blue light glasses filter the correct type of blue light for your desired purpose. In addition, not all screens are LED-based and the type of blue light emitted may vary by manufacturer or device setting. And remember, the main source of blue light (including blue-violet light) is sunlight, even indoors.
