What Liquid Glass Is and How the New Slider Fits In
Liquid Glass is Apple’s translucent interface style that applies glass-like transparency and lighting effects to icons, toolbars, menus, and other system surfaces, while still keeping content readable through tuned opacity and diffusion controls. Introduced with a major redesign, it quickly divided opinion: some people enjoy the depth and reflections, others find that see-through menus can obscure controls or strain their eyes. According to BGR, Apple responded by refining defaults and adding customization options, culminating in a new Liquid Glass transparency slider in iOS 27. This slider, found in Settings, runs from ultra-clear to heavily tinted so you can decide how much background shows through. Liquid Glass cannot be fully turned off, but you can now treat it more like a display setting than a fixed theme, dialing in a balance between design flair and on-screen clarity.

Using the iOS 27 Liquid Glass Slider for Precision Control
The iOS 27 Liquid Glass slider is the centerpiece of transparency control on iPhone and iPad. You open Settings, go to Display & Brightness, then choose the Liquid Glass section, where the earlier Clear and Tinted options are expanded into a continuous slider. Move the control toward the clear end for a brighter, more transparent look where wallpaper and app content show through more strongly. Slide toward the tinted end to increase opacity and contrast so text and icons stand out. Apple says it tuned Liquid Glass in iOS 27 so it “diffuses complex content behind it much more effectively, while also creating more depth and separation,” which should improve readability even before you adjust anything. Combine the slider with Dark appearance and accessibility options to fine‑tune transparency, brightness, and motion independently, depending on whether you prioritize style, comfort, or legibility.
Accessibility Tools: Reduce Transparency, Brightness, and Motion
If you need stronger controls than the iOS 27 Liquid Glass slider alone, Accessibility settings provide deeper customization. On iPhone and iPad, go to Settings > Accessibility > Display & Text Size and enable Reduce Transparency to replace translucent panels with more opaque backgrounds, improving contrast in folders, menus, and system overlays. In the same menu, turn on the reduce brightness setting, labeled Reduce Brightness, to soften some of the intense lighting effects introduced with Liquid Glass. As PCMag notes, this makes a subtle but helpful difference for people sensitive to bright animations. Next, visit Settings > Accessibility > Motion and enable Reduce Motion to tone down parallax and certain Liquid Glass effects, reducing visual busyness. Used together, these toggles let you shape how Liquid Glass looks and feels, even though the design itself remains active in the system.
Matching Controls on Mac and Apple Watch for a Consistent Feel
You can mirror your transparency control iPhone setup on Mac and Apple Watch so Liquid Glass behaves consistently across devices. On a Mac, open System Settings > Accessibility > Display and enable Reduce Transparency; you will see icons, folders, the menu bar, Dock, and widgets become less see-through. Switch the appearance to Dark under System Settings > Appearance if you want Liquid Glass to recede visually even more. On Apple Watch, use the Watch app on your iPhone, go to My Watch > Accessibility, and toggle Reduce Transparency, or do the same on the watch in Settings > Accessibility. Notification panels and Control Center are the easiest places to spot the change, with backgrounds shifting from glassy to more solid. Combine these tweaks with Dark Mode on each device to keep the overall Liquid Glass style while improving clarity and comfort everywhere.
Interim Tweaks Before Full Rollout and Best‑Practice Combinations
Until the Liquid Glass slider reaches all your devices, you can rely on the reduce brightness setting and existing appearance options as an interim solution. On compatible iOS versions, Reduce Brightness under Accessibility > Display & Text Size lowers the intensity of Liquid Glass lighting while you still use Clear or Tinted in Settings > Display & Brightness > Liquid Glass. Dark Mode is another simple but effective adjustment; setting the appearance to Dark on iPhone, iPad, and Mac hides some of the glassy extremes and boosts perceived contrast, especially in media apps and Control Center. Remember that Liquid Glass cannot be fully disabled in current releases, but by stacking Reduce Transparency, Reduce Brightness, Reduce Motion, Dark appearance, and finally the iOS 27 Liquid Glass slider, you can substantially tone it down, making the interface calmer, easier to read, and more personal to your preferences.
