The Lime Lighter displays printed music notation using the traditional five-line staff. New low vision features allow you to magnify the music up to 10 times the original size. You can even edit the music and print it out. But, for most low vision people, this technology will be of interest as a way of reading music comfortably. Our new low vision features provide the special magnification functions needed to display enlarged music in the proper proportions from 1.25 times standard size all the way up to 10 times. For more easily reading text in program menus and dialogs, you have the option to use the built-in features of Windows or third-party magnification programs such as ZoomText and MAGic. You may also want to use those programs to invert the screen image or to change background and foreground colors.
