Just before Yaakov dies, Yosef brings over his sons to receive a blessing from Yaakov.

When Yosef brings them over, the Torah says a few very confusing Psukim in regards to Yaakov's health\physical condition.

At first the Torah says that Yaakov sees Yosef's sons, and asks - who they are.

Then the Torah says that Yaakov is old and therefore he can't see.

But then again Yaakov says himself that he never thought he'd get to see Yosef, let alone see his descendants.

So which is it - can Yaakov see or not?

Is he blind? If the Torah says "he can't see", therefore he's blind - but it seems that he says he can see?!
What's going on over here?

Obviously there's a great learning here - since the Torah emphasizes this!
