Floaters are caused by tiny bits of vitreous gel or cells that cast shadows on the retina. Flashes occur when the vitreous tugs on the sensitive retina tissue.
Signs and Symptoms
- Black spots or "spider webs" that seem to float in the vision in a cluster or alone
- Spots that move or remain suspended in one place
- Flickering or flashing lights that are most prominent when looking at a bright background like a clear, blue sky
Symptoms that may indicate a more serious problem
- Sudden decrease of vision along with flashes and floaters
- Veil or curtain that obstructs part or all of the vision
- Sudden increase in the number of floaters
