A revolutionary app called the KNFB Reader was unveiled last week, combining advanced digital photography with Apple hardware, allowing the blind and visually impaired access to almost any kind of printed text.

The Voice Over function guides the user through the process of taking the picture, and reads the text aloud. It's even capable of reading multi-columned text such as newspaper articles.

No document is too long, and it can help the blind read books that might not be available in braille. It's able to save the documents as well as import and export them.

The KNFB Reader can read in English, French, German, Dutch (Belgian and Netherlandic), Italian, Spanish, Portuguese, Danish, Finnish, Swedish and Norwegian.

It's compatible with every iPhone from the 5 up, including the 5C, 5S, 6 and whatever comes next. It needs iOS 7 or higher for compatibility.

The app is currently available for download for $99.99.
