Screen Magnification
Screen magnifiers help people with visual impairments by enlarging content on the screen. These tools make text, icons, and images easier to see without altering the layout of websites or apps.
Based on guidance from AbilityNet, several free screen magnification tools are already built into common devices, making them simple to activate and customise.
