Digital Screen Overlay

Digital Screen Overlay (DSO) – Colour Overlay App

Digital Screen Overlay (DSO) is a colour overlay app designed to help people with Irlen Syndrome, visual stress, dyslexia, and colour sensitivity read more comfortably on digital screens.

Many people with Irlen Syndrome and dyslexia experience visual distortion, glare, eye strain, or headaches when reading. DSO helps reduce these effects by applying a customisable coloured screen overlay, allowing users to find a colour and tint that works best for their individual needs.

How it works:
Open the app, tap Start Overlay, choose your colour, then exit — your selected overlay remains active across your screen.
(First use requires permission to display over other apps so the overlay can function.)

Key features:

Comfortable colour presets

Adjustable tint strength, opacity, and brightness

One-tap activation

Clean, accessibility-focused design

One-off low price — no ads, no subscriptions.

Whether you’re reading websites, eBooks, notes, or documents, DSO helps reduce visual stress, improve focus, and create a calmer reading experience.

Ideal for: students, parents, teachers, SEN staff, and adults experiencing reading fatigue or visual discomfort.

If you find DSO helpful, please consider sharing it or leaving a review to help others benefit.

Make reading comfortable again.
