Thermal and eye sight issue

I was calling earlier this week with my brother who has never used thermal before. He was scanning with my pulsar monocular for 10 minutes and pretty much lost the eyesight in that eye. Apparently, his eye really dilated and the center of his vision was a big black circle with some light around the edge of his view. He has artificial lenses implanted in his eyes. His eyesight returned to normal in a few minutes.

Anyone ever heard of this?
 
when i use my scanner i scan with my left eye and shoot with my right eye. the thermal creates a dark spot in the middle of our eyes which goes away after a short period.

how it affects an eye with an implanted lens in it, i have no idea but you should have your brother consult with his doctor before he uses it again.
 
My eyes always do that. As soon as I turn on a light I can see fine. Just like when someone shines a bright light in your eyes in the dark. Just had double cataract surgery in September, haven’t noticed any changes from previously using the thermals.

I also scan with left eye & shoot with my right using thermals. He sounds normal from what I’m used to. Really weird when you first experience it !
 
I scan and shoot both with my dominate eye, I believe it's something you get used to.

I had a Wraith night vision scope for a short period of time, I thought the NV was a lot worse than thermal.
 
i scan left and shoot right. Looking into the display of a scanner always has an effect on your night vision to some degree. Kind of hard to explain what I see after taking my eye away from the scanner. Sounds similar to the OP's description for the most part, but I kind of see a red/pinkish hue as well until my eye readjusts.
 
I just use the same eye for scanning and shooting. Need at least one good eye to retrieve and walk out, lol. By the time I get back to the truck it’s back to normal.
 
Left eye don't work so I scan/shoot with the right and have a lens in it for going on 4 yrs now.. As said, Turn the screen brightness down to start and it is somewhat common for that to happen. I would try again and if it occurs again to the same degree, I would be calling the ophthalmologist.
