Eye floaters are a common visual experience that many people notice at some point in their lives. They often appear as small spots, threads, or squiggly shapes drifting across your field of vision, especially when looking at bright backgrounds like a clear sky or a white wall. In most cases, floaters are caused by natural, age-related changes in the eye. The vitreous, a gel-like substance inside the eye, gradually becomes more liquid over time. As this happens, tiny fibers within it can clump together and cast shadows on the retina, which is what we see as floaters. While they may seem unusual or distracting at first, they are typically harmless and tend to become less noticeable as the brain adapts to them.

However, there are situations where floaters can signal a more serious issue and should not be ignored. A sudden increase in floaters, flashes of light, or the appearance of a dark shadow or curtain in your vision may indicate a retinal tear or detachment, which requires immediate medical attention. Certain individuals, including those who are nearsighted, have diabetes, or have undergone eye surgery, may be at higher risk of experiencing complications. Eye specialists can evaluate floaters through a dilated eye exam, allowing them to check for underlying problems. While most cases do not require treatment, staying aware of changes in your vision is important. If anything feels different or worsens quickly, seeking professional advice can help protect your long-term eye health.
