The large print stick-ons virtually double the size of the letters and numbers on a standard keytop. The Braille stick-ons are available with black print on an ivory or bright yellow background or with white print on a black background. This adapter allows both the Big Keys Plus and the standard keyboard to be used together, without having to switch back and forth between the two by plugging and unplugging. These filters are made of high quality optical fresnel lenses which magnify each letter up to two times in each direction without distortion.
Telescopic feature permits selection of desired level of magnification.
You can easily install them on any monitor without using tools. They even have a visor for privacy. The Center-Mount frames hold securely and lift for easy cleaning of the screen. Each pack includes 6 clear plastic adhesive backed raised dots. This switch lets one computer share 2 printers or peripherals or two computers share one printer.
