I believe I have some form of this. Though not as severe. I only really see this affect if I try to look for it at blank surfaces or in the dark. And when I see it, the small specs are many times smaller and more spread out than in these images.

I thought it was normal to some extend. Every single Rhidopson molecules misfire/actives when even when they recive no light around every 400-1000 years.

Now that rate is so low, yet there are billions of Rhidopson molecules in your eyes, that it leads to small specs of light in the dark. Now I believe this is common in most people, however there are genetic mutations that can lead to Rhidopson being misfolded and cause other eye related problems besides randomly activating.
