Bright white screen for light

Most of us stare at our iPhones for far too long, and this constant exposure to a bright screen can strain our eyes, especially in low-light conditions or during the twilight hours. That's where the ability to dim your iPhone screen beyond the standard brightness settings becomes a game-changer. If the screen of your iPhone or iPad is too bright for comfort, the usual solution is to go to Settings ➝ Display & Brightness and drag the Brightness slider to the left, or open Control Center and adjust the corresponding setting from there. However, if the lowest setting offered by the Brightness level just isn't dim enough for you, there's another way to make your screen even darker. This feature is particularly useful if you find yourself needing to use your device in dark environments, such as in a bedroom where a partner is sleeping, or in a dimly lit theater. It's also a boon for anyone with light sensitivity, providing a more comfortable viewing experience that minimizes eye strain and fatigue. Let's look at how to set it up below.Reduce White PointOpen Settings on your iPhone.Select Accessibility from the list of options.Scroll down and select Accessibility Shortcut.Tap Reduce White Point, then drag it up near the top of the list using the three lines icon.Now that's set up, simply triple-click your iPhone's Side button to display the Accessibility Shortcut menu, then tap Reduce White Point. Your iPhone display will now be dimmer than the dimmest setting offered by the standard Brightness level.Reset White PointTo return the white point to its normal level, simply triple-click the Side button again and tap Reduce White Point to uncheck it.Adjust White PointIf the White Point is still too bright (or too dim), you can adjust it manually: In Settings, go to Accessibility ➝

By now, we know that forgoing bright blue lights in the evening is one of the most important steps toward a healthier sleep schedule and circadian rhythm. Blue wavelengths of light signal the brain to wake up and be alert, while suppressing the release of melatonin, the hormone that makes us sleepy. While we definitely recommend ditching the phones and all device screens close to bedtime (wind down and relax!) we understand that may not be realistic for many of you. So, how can you safely use your phone at night without the danger of blue light delaying or disrupting your sleep?The answer: turning our phone screens red at night to eliminate the blue and green light emitted. Let's explore how! Step One: Activate the Red Color FilterNewer iPhone Models (iPhone X and above)Go to Settings → Accessibility → Display and Text Size → Color Filters.Enable Color Filters by tapping the toggle at the top of the screen.Select "Color Tint" as the filter type.Slide the intensity and hue all the way to the right.Older iPhone Models (iPhone 8 and below) Go to Settings → General → Accessibility → Display Accommodations Enable Color Filters by tapping the toggle at the top of the screen. Select "Color Tint" as the filter type. Slide the intensity and hue all the way to the right.Step Two: Creating a Triple-Click ShortcutTo streamline the process of switching between a regular screen and a red-tinted screen, you can set up a convenient triple-click shortcut.Newer iPhone Models (iPhone X and above) Go to Settings → Accessibility. Scroll to the bottom and select "Accessibility Shortcut." Choose the "Color Filters" option from the list.Older iPhone Models (iPhone 8 and below)Go to Settings → General → Accessibility.Scroll to the bottom and select "Accessibility Shortcut."Choose the "Color Filters" option from the list.Now, every time you triple-click the right side lock button of your iPhone, it will seamlessly switch between a regular screen and a red-tinted screen, blocking all blue and green light wavelengths and letting you get a better night’s sleep! Other Lighting Tips For a Good Night's Sleep Use only dim, warm color temperature lightMinimize or eliminate sources of white light in the evening (device screens, overhead white lights, etc.) Keep the brightness of all light at a minimum. Any light, if bright enough, can keep you up! - Dim overhead lights or turn them off altogetherWhile a lot of attention rests on light color, brightness can be equally as important. Too bright a light triggers your pupillary reflex, which tells your brain that it's time to wake up! Turn off any overhead lights and use desk and floor lamps outfitted with warm white light bulbs instead. - Use warmer color

Illuminates your back wall (bias lighting). With a smart wireless controller, it's easy to adjust brightness and color temperature. Its patented clip design mounts on almost any monitor, saving valuable desk space, and it's powered via USB, eliminating the need for extra wires. Check Price on Amazon Keeps Desk Foreground Evenly LitI’ll admit that most desk lamps do this, but light bars do it a little bit better. When your desk is lit up evenly, it makes your monitor’s brightness a bit less intense in your eyes. Monitor light bars illuminate the center of your desk right underneath your monitor. That means your bright monitor visually transitions very well into your lit desk. Few desk lights actually illuminate the center of your desk with a nice wide beam. Monitor light bars on the other hand do this particularly well. Ways To Reduce Eye StrainIf you are on the fence about monitor light bars, check out our article on light bar benefits and our article on how light bars stack up against desk lamps. Whether you use a light bar or not, here are some ways you can relieve some eye strain at your desk today. Use Bias LightingWe touched on what bias lighting is earlier, but basically, it’s illuminating the wall behind your monitor. Without bias lighting, you have a stark contrast between the bright screen and the surrounding darkness. When you add some bias lighting that contrast is gone as the bias light continues to illuminate the area around your monitor. I currently use Govee light bars as my bias light. I have a dedicated review of the light bars here. They are attached to the back of my monitor.

Lower Screen BrightnessAn easy way to reduce the contrast of your monitor from your surroundings is to lower your monitor’s brightness. Screens can get really bright these days, so the

Night. You should be able to see the detail in the coat, not just a void with a head on top. Again, you might need to try a few different shows or movies to get it right. Backlight or OLED lightControls the light intensity of the entire displayToo high and it can cause headaches or eye strain, waste energy and, in some cases, cause premature wear on the TVToo low and the image is too dim and difficult to seeNearly all TVs will have some control that adjusts the overall light output of the TV. It's usually labeled as the backlight control, or OLED light, or something similar. For example, on newer Sony TVs this setting is labeled Brightness, and on Roku TVs there are five settings (Brightest to Darkest) in addition to a backlight control. Whatever the label, this setting is the actual brightness, which is generally separate from the control labeled "Brightness" (see above). You should adjust this setting based on room lighting and personal preference. Brighter rooms and daylight viewing will call for a higher setting, while home theater or nighttime viewing often looks better at a lower setting. On an LCD TV, a bright backlight can wash out the image somewhat and reduce contrast and pop, especially on models that lack full array local dimming. The brighter the TV is, the more energy it will consume, if you're concerned about how much electricity you use. Higher brightness also makes OLED TVs somewhat more susceptible to image retention and burn-in -- although that's unlikely with typical viewing habits, even at maximum brightness.

On the right, when the contrast control is set too high. Notice the lack of detail in the sand and how the clouds are blown out. Geoffrey Morrison/CNETControls the white or bright parts of an imageToo high will erase detail from clouds, snow and other bright objectsToo low will look dim and flatThe contrast control adjusts how bright the bright parts of the image are. There is an upper limit, however. If you set the control too high, it "clips" the whites, making near-white details totally white. This effectively erases any detail in bright objects like clouds without making the image actually brighter. To set contrast by eye,

Used to detect the amount of visible light.In the context of "Duck Hunt," the Zapper photodiode detects changes in light intensity when players pull the trigger. For a brief moment during the trigger pull, the ducks would turn into white blocks on a black screen, and the photodiode would register a hit if it could "see" one of the white boxes. This is why it worked better if you held it directly against the TV — the white box was easier for the photodiode to detect when held up close. The NES Zapper worked with any TV or screen Tushar Mehta/SlashGear When firing at multiple targets, the game would display white blocks around each potential target individually. By detecting the sequential changes in light, the console could determine which targets you had hit.AdvertisementSince this process only took a few milliseconds, you would likely not notice the blackout or the targets flashing while playing the game unless you knew to look for them. Flashing images on the NES were also not uncommon due to its graphical capabilities and were overlooked by most players.Nintendo's implementation helped patch one major issue with older light guns where players would point the gun at any bright light source, cheating the system into believing the targets were being shot. The game needed the contrast of a white box on a black background for the sensor to detect it correctly, and a standard light wouldn't contain a dark background.As a homage to the Zapper's iconic legacy, Nintendo has included the Zapper as a weapon in the Splatoon game series and the "Duck Hunt" dog, along with a friendly duck, as a character in the "Super Smash Bros." series.
