Hysteric blindness is a known thing. So is visual migraine. This latter neurological condition/phenomenon, ime, entails a disappearance of the central visual field. This begins as a small, jagged area of iridescent shimmering in the centre of my field of vision. The shimmering procedes to grow outwards as a border around a central area of nothingness. My peripheral vision remains intact; my usual course of action if this starts happening is to lie down and relax and wait for it to run its course. Fortunately this occurs quite rarely for me, less than once a year but sometimes in bouts. It must be six months since the last time it happened.
Does this sound familiar to you? What are your stress levels like? You seem somewhat anxious these days. If an unusual phenomenon occurs, just relax and observe it. You cannot afford to get into a panic if bizarre phenomena occur while using DMT! That, and other high weirdness, is very much part of the deal.
If the visual changes persist after the DMT effects have worn off it would be wise to seek medical advice from an optician or an ophthalmologist.
