Eye floaters are those tiny specks or threadlike shapes that drift across your vision, often most noticeable when looking at a bright surface like a clear sky or a white wall. While they may seem distracting, they’re not outside the eye at all—they come from changes within it, which may be detected by an eye exam in Pittsburgh, PA.

What Are Floaters Made Of?

The inside of the eye is filled with a gel-like substance called the vitreous. Over time, this gel begins to shrink and form microscopic clumps. When light enters the eye, those clumps cast shadows on the retina, which appear as floating shapes. That’s why floaters shift when you move your eyes, then seem to dart away when you try to focus on them directly.

When Should You Worry?

In most people, floaters are a harmless byproduct of the aging process. Still, certain changes need attention. A sudden burst of new floaters, flashes of light, or a dark curtain across part of your vision can indicate a retinal tear or detachment. Those conditions require immediate care, as they can threaten long-term vision if untreated.

Living With Floaters

For many patients, floaters fade into the background as the brain learns to ignore them. If they become severe enough to interfere with daily activities, there are procedures that may help, though these are rarely necessary. What matters most is scheduling regular eye exams so your doctor can determine whether floaters are routine or part of something that needs prompt treatment.

Eye floaters may be common, but they’re worth understanding, because they can also be a symptom of something wrong. By knowing what causes them and when to take action, patients can feel more at ease and confident about their eye health. Visit your optometrist in Pittsburgh, PA to learn more.
