"Orwell feared that the truth would be concealed from us. Huxley feared the truth would be drowned in a sea of irrelevance. Orwell feared we would become a captive culture. Huxley feared we would become a trivial culture, preoccupied with some equivalent of the feelies, the orgy porgy, and the centrifugal bumblepuppy. As Huxley remarked in Brave New World Revisited, the civil libertarians and rationalists who are ever on the alert to oppose tyranny 'failed to take into account man's almost infinite appetite for distractions.' In 1984, people are controlled by inflicting pain. In Brave New World, they are controlled by inflicting pleasure. In short, Orwell feared that what we hate will ruin us. Huxley feared that what we love will ruin us.” ― Neil Postman, Amusing Ourselves to Death: Public Discourse in the Age of Show Business
You can create blindness by turning the lights in the room off or by flooding the room with light. Orwell worried that Big Brother would have his finger on the off switch, Huxley worried that we would add more lights and get rid of the switch. Either way, distinction and differentiation are obliterated. Orwell imagined a society starved for meaning whereas Huxley imagined a society so full of crap that it could not fit a bite of meaning into it. Orwell assumed the tyranny would come from without, Huxley predicted the tyranny would come from within. Orwell imagined the threat of pain would be the best weapon whereas Huxley's imaginative powers wielded pleasure. The one was the desire for satisfaction and the other was the burden of over saturation.
