What symptoms characterize floaters?

Floaters are visual phenomena that appear as spots or threads moving across a person's field of vision, often described as looking like small shadows, specks, or cobwebs. These are typically caused by the presence of tiny pieces of debris within the vitreous humor, which is the gel-like substance filling the eye. As light passes through the eye, these particles cast shadows on the retina, leading to the perception of floaters.

Individuals may notice floaters when they look at a plain background, such as a clear sky or a blank wall, where they become more pronounced. Over time, floaters may become more noticeable, but they are generally harmless and common, especially with aging or certain eye conditions. Understanding floaters is crucial for differentiating them from other eye issues that may require immediate medical attention, such as retinal detachment, which typically presents with additional symptoms.
