If you type under low-lit conditions and have difficulty recognizing keys on your keyboard, maybe you should try the Oversized Keyboard.
The Oversized Keyboard is designed for people who are visually impaired or have limited dexterity. It features extra large letters and numbers that are easy to read and stroke.
The Oversized Keyboard measures 17 3/4 x 6 1/2 inches and is compatible with PCs only.
The keyboard sells for $20.
Implications - It would make a great gift for grandmas and grandpas with dwindling eyesight, or for those who don't feel like wearing their lenses at the computer. This will be your "type" of keyboard.
