A screen magnifier is a tool that enlarges the content displayed on a computer or mobile device screen. It helps users with visual impairments or those who need to see details more clearly. This software or hardware feature allows individuals to zoom in on text, images, and other elements, making them easier to read and interact with. Screen magnifiers can be found in various operating systems, such as Windows and macOS, and are often included as accessibility options. They can also be used in conjunction with other assistive technologies, like screen readers, to enhance the overall user experience for those with vision challenges.
