So it's natural to sometimes see visual artifacts in neurotypical adults.

We don't actually see with our eyes, but with our brains. As a neural network, the brain builds the visual image in one part, and then filters out parts of the image in another part. Kind of like how we have a sense of touch but we don't feel our clothes all the time.

With Visual Snow syndrome, the part of the brain responsible for spatial logic and building the visual image has had all the circuit breakers flipped to on. This means that the image the brain is building is at 100% all the time, and overloading the filters. Just like zooming into a 780p image on a 4K screen, the visual artifacts are visible in everything.

Unless you're seeing them 90-100% of the time you're awake, I wouldn't worry too much about it as it's natural.
