REDMOND, Washington — Microsoft on Monday expanded testing of Screen Tint, a new Windows 11 accessibility feature that applies a customisable colour overlay to reduce eye strain, to additional Windows Insider channels. The company detailed the rollout in a blog post.

Screen Tint allows users to apply a coloured filter across the entire display, with adjustable intensity and hue. The feature is designed to help people with light sensitivity, migraines, and conditions such as visual stress, building on earlier accessibility tools including Color Filters and Night Light.

The feature first surfaced in preview builds released to the Windows Insider Program in late June. Screen Tint sits within the Settings app under the Accessibility section and can be toggled with a keyboard shortcut.

Microsoft invited Insiders to submit feedback through the Feedback Hub. The expansion reflects the company's continued push to position Windows 11 as a more inclusive platform ahead of broader 2026 updates.

Accessibility advocates have urged operating-system makers to offer finer control over screen colour and brightness, citing the growing time users spend in front of displays. Microsoft has not confirmed a date for general availability. Features tested in the Insider channels typically reach mainstream Windows 11 users through cumulative updates over the following months, though some are dropped before release.
