Fun fact: The movie took place 30 years after the devastation and it took 3 years for him to dictate totaling 33 years which was the age that Christ died.
Also, here's more evidence that Eli was not blind:
1. He sees the car on the side of the road at the beginning and goes over to it to check for something (the radio i assume)
2. When he shoots the cat, he walks over to it, picks it up, looks it up and down and also glances at his arrow to make sure its ok..
3. After falling asleep with the ipod in he looks at it when he wakes up and sees that the battery is dead..
4. Also when hes leaving after spending the night in the town, he is going to pick up his radio that was charging, when he gets there the guy has it plugged up still and Eli points to the 2 cables, and tells the store man to take them off that he has to go now.
5. When he and Solara are walking and he says "Walk by faith, not by sight", he is looking at the ground as he walks, watching where he walks.
6. When Solara asks him to read some of the book to her, he looks at her, then over his shoulder, making sure there was no one around.
7. Finally, as he approaches the edge of that overpass, he stops and hides behind the rock, and several times peeks over it to see the hijackers killing those 2 people, then remembers the guy in the bar when he comes up to him for shooing the cat..
These are just seven of many examples.
There you have it, folks. Eli was not blind. The Bible being braile was to protect it should it fall into the wrong hands, that's all. Not many sighted people can read braile, but if someone can memorize the entire King James Bible, then they can certainly teach themselves how to read braile. IF he was in fact sight impaired, then God enabled him to see, despite his handicap.
