Most floaters are harmless, especially when they appear gradually and remain stable. However, they can also develop after eye inflammation, bleeding inside the eye, eye surgery, or changes in the vitreous that pull on the retina.
A sudden shower of new floaters, flashes of light, blurred vision, loss of side vision, or a dark curtain-like shadow can signal a retinal tear or detachment. These symptoms require prompt evaluation by an eye-care professional because delaying treatment can threaten vision.
If new floaters appear, arrange an eye examination, especially if they are persistent or bothersome. Regular eye exams, UV protection, managing conditions such as diabetes, and avoiding vigorous eye rubbing can support overall eye health, while many harmless floaters become less noticeable over time.
