Keys-U-See™ Large Print Keyboards are perfect for anybody who has a hard time seeing the letters on their computer keyboards. They are also great for anyone who works in low light conditions or is learning to type. Our Large Print Keyboards come in a variety of colors including our specialty keyboard designed with yellow keys and black type - a scientifically proven combination that helps those with certain types of visual impairment.

The choice of effective colors used for our Keys-U-See™ Large Print Keyboards is not arbitrary but is guided by innate human visual and cognitive mechanisms. Certain color combinations enable better detection and improved legibility of text. Brightness contrast, along with size and viewing distance, is the prime determinant of print legibility. High brightness contrast is created by some color combinations but not by others. Black/yellow are the best custom keyboard combination because they provide the highest brightness contrast. Independent research studies have confirmed by experiments showing black/white and black/yellow produce best legibility.

Further, “Positive contrast” is the case of a light object on a dark background such as white print on a black field. In our case, we offer brilliant yellow keys contrast against a black keyboard and black lettering which has proved to be our most popular custom keyboard model for individuals with vision problems.
