Geometric patterns in vision

[Katelyn1995]

I’m 22 years old, female from Australia, I am very hyper aware of visual things most people don’t think about. In the last two years I’ve seen three eye specialist and had an MRI for unrelated issues.

I’ll go straight into the thing I’m worried over; when I go from a dark room straight into a light room and turn light on, if I immediately look at a blank wall that’s bright, as my vision “adjust” to the brightness, I always see for a couple seconds a geometric/lines in my entire visual field and then it vanishes, I do not ever see this under any other circumstance, I don’t see it in a dim room upon opening eyes, not from just waking up and if I were a normal person and just woke up and carried on with my day and didn’t do this odd experiment - I’d never know.

Does this sound like a normal phenomenon or? I’m pretty scared and can not find anything on google at all

In one way or another there are many posts like yours. As long as you have had 3 exams, a MRI and nothing changes quit worring and move on with your life. The eye has 3 systems for seeing: one for bright light (photopic) one for night (scoptomic) and one in between (mesoptic)  When people awake from sleep or go into a different lighting situation these phenomena, some people, especially those hyperaware or anxious, may see different patterns or a 'spoke'  these fade as the eye "shifts gears' and adjusts to the new situation. If it was something serious it would have progressed or new symptoms would have appeared.

"Spot" not "Spoke"

Thankyou, the only google thing I ever found in relation to it was Charles bonnet, however I have no vision loss and is it true what I’m seeing is NOT an hallucination since it’s brought on by certain circumstances on purpose?

Your description is not that of a hallucinatio
