  There are many ways to learn to read (much) faster, but the first step is
  generally to acquire the motor skills and to learn to move your eyes and
  refocus at a very quick and steady pace.  This takes quite some time,
  because, naturally, comprehension will suffer during this training, but
  the key is to focus on the speed and let comprehension follow, not to
  believe that missing something is so fundamental that you have to go back
  and re-read it or slow down.  Then, learn to see a larger area of the
  line -- most people read in an area on the paper only a quarter of an
  inch wide, but you can expand this to at least one and a half inch,
  sometimes two.  Reading glasses that correct for astigmatism is necessary
  to make this work well, as even a slight case of astigmatism may produce
  blurry vision and cause a strain to recognize words unless they are dead
  center in your focus area.  It follows that you can read at a greater
  distance from the screen/paper and using smaller fonts the better your
  corrective lenses are.  This effect should not be underestimated.

  Also, approach reading as you approach other sensory input: increase your
  observational skills by learning to soak up as much as possible as it
  flows by.  Nature has no rewiding button -- treat reading the same way.
  This is generally a question of concentration and reading with a definite
  purpose to understand or visualize what is presented to you.  In this
  sense, reading faster is just a case of increasing your internal clock
  speed.  Most people can do this with no problem, but few people make a
  habit of it, because it does require more mental energy to be spent both
  in increasing and maintaining concentration.  I believe it is a question
  of whether you can also "listen" to a text instead of wanting to make
  sense of it or make it fit your preconceptions of what it "should" say.

  Some people seem to approach the world with a prescriptive attitude -- or
  forcing the world they deal with to conform to their current thinking --
  while others never stop observing it in order to form their current
  thinking.  Most of the former are unable to understand that the latter
  type even exists because they are guided by their preconceptions, not
  their observations.  In any case, those who are able to observe the flow
  of information thet they are subjected to, can also learn to read fast
  mechanically and decide to focus more or less on what they read, somewhat
  like having CNN or some news-only radio station run in the background.
  The sensory input to which we are naturally prepared to be subjected is
  truly vast, and so much more than reading a page or a screen offers, yet
  the amount of information that becomes the subject of conscious awareness
  if quite limited -- unless one concentrates on absorbing first and
  selecting afterwards.

  Strangely, many who start to read faster observe that they get much
  better reading comprehension from reading mechanically faster and
  "letting go" of their need to comprehend fully at all times, because they
  allow more of the comprehension to proceed less linearly.  This also
  relaes to how we deal with speed.  One of the major reasons that older
  people drive more slowly than younger people is that their processing
  speed is so much slower that sensory overload incurs below 40 mph, while
  a younger person who has been trained to speed up his cognition can
  easily drive more safely at 100 mph.  Things like talking to another
  person in the car, listening to the radio (with varying focus) or talking
  on a cellular phone (handsfree or not does not make any difference) eats
  away at the concentration and require reduced speed.  The same goes for
  reading, although the ability to block out annoyances has no safety risk
  associated with them.

  In a nutshell, this is all about concentration.

  In a fight against something, the fight has value, victory has none.
  In a fight for something, the fight is a loss, victory merely relief.
