Fuzzy TV vision

When I view the world there is a layer of very small, very clustered dots that move. Very similar to the fuzzy dots overlaying an analogue TV. It's always there and never goes away or changes even when closing the eyes. It is more noticeable in artificial light such as a classroom or looking at a computer screen but also still there in natural light situations. I've had this since I was a young child. Does anyone know what this might be?

It is not the same as 'floaters' as it is uniform and covering my whole vision

Sounds like visual snow.

Thank you! I looked this up and it's exactly what I experience

Hello, it sounds exactly the same as what I have which is visual snow but it's not recognised so can't be diagnosed or treated. Very frustrating.
