There have been a lot of theories online but they all seem as failures mostly. After watchin some scenes of the game I got to think that Riku carryed the blindfold becouse otherwise he would release Ansem. that's why the King is suprised to see Ansem in the forest scene, becouse he was in the body of riku. You can see it pretty clearly after playing trough the Re: Chains of Memories game, KH2 and watching the revealed scenes on youtube or KHinsider. Not noticing this would be like not noticing a fat kid in a dark room with a neon sign above his head that would say I'm here(shhhh...)

The blindfold was to help Riku, because his eyes couldn't lie. So incase they were, he would but the blindfold on.

Yes also, he knew that it would protect riku as well, for the best.

I always wondered how he still managed to see things? Or am i completely missing the point of being blind folded?

The king was shocked because he didn't know who that was until riku put the blind fold over him after the fact.

I think blindness of Riku will be explained in KH 3...

also he used it for power that is why he turned into xehanort in final mixs because his eyes couldnt be disceived.

Riku was blind folded to hide his secret but the king found out so he's been living a secret for a while.
