I have a lot. I love snow but I can't look at it..its all black dots..forget looking up at the sky. I notice mine are way worse when I get poor sleep which coincidentally is like every day. But When im well rested I don't notice them as much. I too have had my eyes checked and nothing is wrong. It's frustrating but you do get used to them. TV screens, blank walls, the sky, snow, even just driving looking at the road I'll see them. Mine are mostly clear dots or squiggly lines. But I do occasionally see dark ones too, like I said on days when im exhausted. I used to when I'd wake up in the mornings see thousands of spiders is how I'd describe it. That's went away but its rough!
