What the hell are those?
Vitreous floaters: loose strings of dead cells floating (literally) inside your eyeball.
If you only see one or two, that’s kinda normal. If you see bunches and bunches…time for an eye doctor.
ETA: Less’n you meant skeeters. Or hummingbirds. Or the neighbor kid lost a balloon. Or…
Martians
It could also be white blood cells in your eyes: You Can See Your Own White Blood Cells Flowing Through Your Eye!
They are the scouts of the old ones, keeping an eye until the time is right. If you gaze at them too long they will notice you.
If you follow them, you will find everything you ever lost.
