You do not have to concern yourself with comprehension at first. Just try to expand the focus of your mind as you go through groups of words. Try exercising this by scanning through a text document with emphasis on speed and word recognition. Contrary to what some believe, your mind is neither slow nor limited to a certain number of words per minute. If you train your eyes to scan and recognize quickly, your mind will follow suit.
After this sort of exercise, you will want to test your comprehension next. You could use any book to perform this, or you could use a reading application especially designed for this purpose.
