Zoom tool (software)
Many software applications have the faciltiy to allow you to zoom in closer on the work being displayed on the screen.
Typically, you can choose to zoom in at different magnifications from 100% to around 500%.
This can be useful for people with poor eyesight. There are also specific commercial applications that are designed to help with visual impairment.
Tablet computers also allow you to magnify part of the screen with a certain gesture of the fingers (the specific gesture needed varies on the tablet computer brand).
