Nielsen Norman Group published a piece with the headline "Liquid Glass Is Cracked, and Usability Suffers in iOS 26," and the word cracked is doing real work there: the material's legibility falls apart in live, moving, tap-driven use, exactly where Apple needs it to hold. Over on r/UXDesign, practitioners were asking the blunter version of the question in a thread titled "Besides visual, what problems does liquid glass solve?", flagging the performance and accessibility costs against a payoff that's mostly optical. So the design world's one substantial critical take on the biggest iOS visual overhaul since iOS 7 is a usability takedown. And yet the look is spreading fast across branding decks, social content, packaging renders and album art. That gap makes sense once you notice what those uses have in common: none of them have to stay readable while scrolling behind a live camera feed at 120fps.
Search "liquid glass design" today and page one is Apple's own newsroom post, the developer docs, the WWDC session video, a Wikipedia entry, and the NN/g piece. Nobody is writing about Liquid Glass as a material you can pick up and put to work outside a phone screen. The material itself has barely made it into a studio yet.
What Liquid Glass Is, Optically
Glassmorphism as we've known it since the Big Sur and Windows 11 era is a translucent panel with a background blur behind it. Frosted, flat, easy to reason about. Liquid Glass adds physics. As freefrontend.com puts it, the surface carries "a realistic, fluid distortion" achieved through refraction, warping the content underneath instead of only softening it. Apple describes a material that "reflects and refracts its surroundings" while morphing in response to what's happening: tab bars shrink on scroll, then bend the content around themselves when active.
Three things are happening at once. The surface refracts and bends whatever sits behind it. It throws a specular highlight, a hard bright spot where a light source hits the curve. And it deforms as content moves underneath, which gives you that wet, liquid reading. Visily's read is right that this is a continuation of glassmorphism pushed further, an escalation of the frosted look into something with real optical behaviour. It is also, per the same body of criticism, the exact set of properties that turns a live interface into a contrast problem.
Why It Works Better Frozen Than Live
Low contrast, unpredictable legibility, a surface that has to keep reacting to whatever passes under it: those are the failures NN/g documented in a moving UI. Take motion and interaction out of the equation and every one of them flips into an asset. A static logo reveal doesn't need to stay legible while you scroll past it. A product shot has one composition, lit once, resolved. A poster or a packaging render gets to place the refraction and the highlight with intent and then hold them there forever. The material that fights you in an operating system settles down the moment you stop asking it to react in real time.
The interesting part here is the aesthetic outliving the OS feature that popularised it. Apple gave the look a name and a stage, and working designers took the visual grammar somewhere the accessibility argument doesn't apply. This is the same territory we've been tracking in grain, glass and gradient having a moment and in the broader glass, chrome and static hyper-digital swing.
Real Refraction Versus Prompted Refraction
Convincing wet glass carries an optical logic. A creator building a real refraction effect models how light bends through a curved transparent body, then places the specular pass with intent so the highlight lands where the geometry says it should. That's why it reads as glass and not as a sticker. Prompt an AI generator for a "glass UI" image and you get refraction that's physically incoherent: highlights that don't agree with the distortion, bent edges that lead nowhere, because there's no optical model underneath, only pattern-matching against a pile of other glass pictures. The eye clocks the difference immediately even when it can't name it. Built effects hold up under scrutiny because someone did the physics; the generated ones fall apart the second you look at where the light is supposed to be coming from.
Liquid Glass Overlay Effect by Divided.co
The most direct route from the iOS material to a flat file. Divided.co's Liquid Glass Overlay Effect is a single Photoshop pass that gives text, logos or shapes real depth, refraction and shine in one move. Drop your mark in and it comes back reading as a glossy glass object, curved and lit, with the specular highlight sitting where it should. This is the glossy, wet end of the material, the version with the hard bright catch on it, built for branding and social work where you want the surface doing the talking.
Clarity Glass Overlay Effect by Divided.co
When the brief wants the frosted, diffused reading of glass instead of the high-shine one, Clarity is the sibling that handles it. A set of four Photoshop actions that lay a blurred, textured glass layer over an image, leaning into fluted and wavy surfaces. This is the moody, dramatic corner of the material, higher contrast, more mystery, closer to a pane you're looking through than a solid you're looking at. Good for editorial and poster work where you want atmosphere rather than a polished object.
Crystal Prism Photo Effect by Pixelbuddha
Push past the panel and into real prism behaviour and light starts splitting into colour. Pixelbuddha's Crystal Prism Photo Effect works like a kaleidoscope, repeating and refracting an image into fractured geometry with colour separating out along the edges. Its three effects — triangle, kaleidoscope and prism lens — sit on editorial spreads and album art far more comfortably than on any UI-style panel. It's the material stopped being about legibility a long time ago and started being about spectacle.
Prizm by Studio 2am
Built in-house, Prizm gives you the look of shooting through prisms and glass objects in a single step, a set of 10 high-res PSD files in portrait and square sizes ready to composite over real photography. Where the overlay effects work on vectors and flat shapes, this one is made for real photographs: fractured light, dreamy overlaps, that y2k lens-flare-through-a-crystal feel that reads immediately on album art and social content. If you shoot, this is the glass treatment that sits on top of your own frames.
Refracto 33 Patterned Glass Effects by Studio Dusk
Not everything wants the smooth, corporate iOS reading. Studio Dusk's Refracto 33 gives you 33 ribbed, textured, patterned glass effects, the kind with structure in them, warm and tactile where the phone version is cool and clinical. Pick a preview, swap your image in, and you get a physical, hand-touched version of the same refraction idea. This is glass with grain and grip, better suited to fashion and editorial than to anything trying to look like a settings menu. One of our staff picks for good reason.
58 3D Glass Shapes by Softulka
Sometimes the composition needs real glass geometry sitting in it, not a treatment laid over the top. Softulka's 58 3D Glass Shapes are pre-rendered dimensional objects, crystals, cubes, spirals, stars, triangles, each one built as a proper transparent solid. Drop them into a layout and they behave like real geometry, catching light and casting refraction on their own terms. These pair well with the kind of shape-driven work we got into in our geometric shape systems piece.
Debossed Glass Metal Mockup by Pixelbuddha
Proof the material logic has already reached brand presentation work. Pixelbuddha's Debossed Glass Metal Mockup sinks a logo into a brushed metal panel where the recess catches a glossy chrome reflection and the surrounding steel holds a soft directional sheen. A Smart Object presses your artwork below the surface. It's refined, corporate, expensive-looking, the register you reach for when a client wants the mark to feel like a physical object in a lit room. The glass-and-metal surface treatment showing up in a logo mockup is exactly how a UI material becomes a branding one. It sits comfortably next to the industrial, specced-up direction we covered in tech spec replacing clean minimalism.
The Look Has Left the Operating System
Apple is still reworking the material more than a year on. Coverage from mid-August 2026 notes a redesigned Siri icon in the iOS 27 beta with an updated dynamic liquid glass treatment, which tells you the OS-level implementation is still unsettled. That instability is the point: the surface Apple keeps revising in software has already broken loose from the software. Refraction, the specular highlight, depth through distortion, those read as a general-purpose surface treatment now, usable on a poster or a bottle render regardless of what ships in the next beta. If you want more of this material to work with, there's plenty more glass to dig through. The OS feature can stay cracked. The look is doing fine on its own.
