Lisa, Lubna, Alexandra, Hadas and Natalie:
When reading we DECODE the word by activating prior knowledge of letter sounds or experience based on exceptions from past experience. After reading a word multiple times our brains "photograph" the word and it enters or visual memory by creating an image of the word thus helping us to read it faster and with greater accuracy.
Stronger readers are able to predict words and therefore are able to gain speed and accuracy thus helping them focus on content and not just the act of reading.
In the most advanced stage of reading, you are able to read and comprehend content even when the writing contains multiple errors (this means you have become an English teacher)
