This is the real component, not a recording. Move the pointer over it, then adjust the renderer settings.

Fragment shader

<RefractionLens quality="low" />

2. Usage

Glass lens with chromatic edge dispersion. npx coloxo add refraction-lens copies this effect in a Tailwind project or a Coloxo CSS project, and adds @coloxo/ui to package.json. You can also import it from @coloxo/ui/visuals.

3. Performance notes

Effects render on demand and dispose their GPU context when unmounted.

Every effect pauses when scrolled out of view or when the tab is hidden, so an idle page costs nothing.
quality caps the device pixel ratio. Keep it at low when several effects share one viewport.
With respectReducedMotion enabled, the effect renders a single static frame instead of animating.
The output is a decorative canvas hidden from assistive technology. Never place essential content only inside the effect.
