Most people see the whole tree in one or two glances. This is what we call Natural Vision. You see, in first grade we were taught how to have tunnel vision. Most people can only see one word at a time. You may as well read through a straw.
Tunnel vision is unnatural and fatiguing to the eyes.
You need to look at a page of print with more Natural Vision so that you are seeing several words at once. In fact, let s pretend that each page of print is just a picture of a tree, with each word being a leaf. They are just to SEE the words. Some children are able to see all the words on a page in less than 10 seconds. A few in less than 5 seconds.
