Dissociative Identity Disorder Patients Show Vision Shifting Between Personalities in Seconds

What was said

"One of these people, one of these personalities, could have really poor vision. They might need so-called Coke bottle glasses, like really strong glasses. And then they switch personality, not even knowing that it happened or how they did that, and all of a sudden, the new personality, the new identity, has 20/20 vision, and that shift happened in a matter of seconds."

The presenter cites cases of dissociative identity disorder where patients experience dramatic eyesight changes—from requiring very strong glasses to perfect 20/20 vision—when switching between personalities within seconds, with the same physical eyes and brain. This phenomenon is presented as evidence that vision is not purely physical but involves belief systems and neurological states that can radically alter visual acuity.
