Eye floaters are small spots, threads, or cobweb-like shapes that drift across your field of vision. They are especially noticeable when looking at a bright background, such as a clear sky or a white wall. In many cases, floaters are a normal part of aging and occur when the gel-like substance inside the eye, called the vitreous, begins to shrink and change over time.

If you suddenly notice new floaters, it is important not to panic, but you should pay close attention to any other symptoms. A small number of floaters that develop gradually are often harmless. However, a sudden increase in floaters, especially when accompanied by flashes of light or a shadow in your vision, could indicate a more serious problem such as a retinal tear or retinal detachment.

The best course of action is to schedule an eye examination with an eye care professional. During the exam, the doctor can inspect the retina and other structures inside the eye to determine the cause of the floaters. Early detection is critical because certain retinal conditions can lead to permanent vision loss if left untreated.

Most floaters become less noticeable over time and do not require treatment. Learning to move your eyes up and down can sometimes help shift them out of your direct line of sight temporarily. Nevertheless, any sudden changes in vision should always be taken seriously. Prompt medical evaluation can help protect your eyesight and ensure that any underlying condition is addressed as quickly as possible.
