The magnifier in windows vista is easy to use. It is effective for low vision students because it allows them to see things on the screen more clearly.
First go to the start menu and type ease into the search bar.
Ease of Access center will pop up click on that.
Then click on the start Magnifier button.
Then a window will pop up that magnifies whatever it is held over. You can change the size of it by clicking and dragging on the sides.
