What are these |squiggly lines in my eyes?
They are floaters: A blurry spot that seems to drift in front of the eyes but does not block vision.

The blur is the result of debris from the vitreous of the eye casting a shadow on the retina. The spot is the image formed by a deposit of protein drifting about in the vitreous, the clear jelly-like substance that fills the middle of the eye.

Vitreous Floaters in the Eye
Floaters are often described by patients as spots, strands, or little flies. Floaters are usually benign (not serious). They can, however, occasionally result from a separation of the vitreous gel from the retina.
