Eye floaters are small shapes like squiggly lines, specks, or cobwebs that drift across your vision, especially against bright backgrounds. They are typically caused by age-related changes in the vitreous, the gel-like substance inside your eye. As we age, microscopic fibers clump together and cast shadows on the retina. While usually harmless, floaters can sometimes be linked to eye infections, uveitis, or retinal tears.

You are at higher risk if you are nearsighted, have had cataract surgery, have diabetes, or are aging. Generally, floaters are benign, but a sudden increase in floaters, flashes of light, or a dark curtain moving across your vision signals a medical emergency. These symptoms could indicate retinal tear or detachment and require immediate attention to prevent vision loss.

Eye doctors diagnose floaters through a dilated eye exam. In most cases, no treatment is needed as floaters become less noticeable over time. For severe impairment, options include vitrectomy (surgery to replace the vitreous gel) or laser therapy. Both carry risks like infection or retinal damage and are reserved for serious cases.

Lifestyle tips include moving your eyes up and down to shift floaters out of your line of sight, eating a diet rich in omega-3, vitamin A, and zinc, and avoiding smoking. Regular eye check-ups are vital. As Dr. Rick Ansorge advises, if you experience sudden vision changes, seek medical advice immediately. Staying informed and proactive is your best defense.
