If you’ve ever seen tiny specks, threads, or cobweb-like

shapes drifting across your vision—especially against bright backgrounds—you’ve likely

experienced eye floaters. These dots, squiggly lines, or

strands move with your eyes and are most noticeable on clear, light surfaces.

Most floaters are harmless, but knowing their causes and

warning signs is key. The most common cause is age-related changes in the

vitreous humor—the gel-like substance inside the eye. As

it shrinks, small clumps form and cast shadows on the retina. Other causes include

posterior vitreous detachment, retinal tears or detachment,

inflammation, bleeding, and complications from surgery or certain medications.

While often benign, floaters require attention if you

suddenly notice many more than usual, flashes of light,

loss of peripheral vision, or eye pain. These symptoms

may signal retinal detachment or other urgent problems.

Eye doctors can evaluate floaters with dilated exams,

ultrasound, or optical coherence tomography (OCT).

Most cases need no treatment, as the brain gradually

learns to ignore them. Severe or disruptive floaters

may be treated with vitrectomy—surgical removal

of the vitreous—or laser therapy to break them apart.

Regular eye exams, protective habits, and prompt

care for sudden changes help preserve long-term vision.
