Electronic reading devices, such as the Kindle, allow the user to adust the font to a wide range of sizes with the press of a button. The iPad allows the reader to zoom images and text by "pinching and expanding" ones fingers in addition to pushing a button.
Kindles and iPads offer excellent contrast, and the latter offers brilliant colors. The wireless feature allows portability and comes in screens as large as almost 10 inches. By trying out various devices at the vendor’s store, people with AMD can find the reader best suited for them.
