Eyes :: Pin Point Flashes In My Vision

I have been seeing pin point flashes in my eye for a long time, a few months now. they vary in color from red to silver. they last for half a second and appear out of nowhere with no warning signs. i have also been seeing a lots of floaters which appear as moving dark black lines rather than squiggly bubbles ( i see the squiggly bubbles too but they happen rarely). the dark lines don't usually bother me unless im looking at a wall or when i'm outside. if i'm outside during daytime the frequency of seeing the dark lines greatly increases even if i'm just looking at the ground. oh there's also something else, whenever i look at the sky at daytime i see a lot of glitter moving around almost looking like shooting stars.
