I recently played a typing game: http://www.rapidtyping.com/online-typing-games/fruit-swordman-typing.html
When I try to read the words that jump from the bottom, I can't read them until they make it to the top (their movement's speed is lower). Is this normal? When the words are moving in a higher speed, I see the words written a couple of times (sort of a blur, imagine you are viewing the whole world a couple of times, only that each view is a bit positioned differently).
Difficult to say if you're truly experiencing any visual problems based on a specific situation with moving text. In general, do you have problems with your peripheral field down below versus up top? Based on your prescription, there does not appear to be any astigmatism. It would not hurt to get your glasses checked to see if the size of or positioning of the lens is such that your view looking down varies with that straight ahead or looking upward. Otherwise, if you are experiencing any other visual compromise, a full complete exam by an ophthalmologist could exclude any serious issues.
