Seeing little spots, specks, or squiggly lines drifting across your vision? Eye floaters are common, but sudden changes can be a warning sign that your eyes need immediate attention. Here’s what to know and when to seek care.

Have you ever looked at a bright sky or a white wall and noticed tiny spots or squiggly lines floating across your vision? These are called eye floaters, and they are common, especially as we get older.

While most floaters are harmless, new or sudden changes in your vision should never be ignored. Knowing what to look for can help you protect your eyesight.

What Are Eye Floaters?

Eye floaters are small shapes that appear to drift through your field of vision. They may look like dark specks, threads, squiggly lines, or tiny cobwebs.

They often develop as the gel-like substance inside your eye changes with age. Small fibers can clump together and cast shadows on the retina, creating the appearance of floating spots. You may notice them most when looking at something bright.

Many floaters do not require treatment. However, an eye examination can help determine whether they are related to normal aging or a more serious eye condition. National Eye Institute

When Should You Worry About Eye Floaters



A sudden increase in floaters can be a sign of a retinal tear or retinal detachment, both of which require prompt medical attention.

Watch for these warning signs:

• A sudden increase in the number of floaters
• Flashes of light in one or both eyes
• A dark shadow or curtain across part of your vision
• A sudden change or loss of vision

If you experience these symptoms, seek immediate evaluation by an eye care professional or go to an emergency department. Retinal detachment is a medical emergency, and prompt treatment can help prevent permanent vision loss. Do not wait for a routine eye appointment.

Can an Eye Exam Detect a Serious Problem?

Yes. A dilated eye examination allows an eye care professional to examine the retina and look for signs of a retinal tear, detachment, or other eye conditions.

Floaters can have several causes, and it is not always possible to tell whether they are harmless based on how they look or feel. Even if you have experienced floaters before, a sudden change deserves attention.

Routine comprehensive eye exams are also important because some eye diseases develop with few noticeable symptoms in their early stages.
