What Are Floaters? Should You Be Worried?

Floaters are tiny spots, threads, or cobweb-like shapes that drift across your field of vision. They are especially noticeable when looking at a bright background like the sky or a white wall. In most cases, floaters are harmless and occur naturally with aging, but sometimes they can signal a serious retinal problem.

What causes floaters?

Inside the eye is a gel-like substance called the vitreous. As we age, this gel becomes thinner and may form tiny clumps that cast shadows on the retina, appearing as floaters.

Common causes include:

• Natural aging changes in the eye
• Vitreous degeneration or shrinkage
• Eye injuries or inflammation
• Retinal tears or detachment in serious cases

When should you worry?

Although many floaters are harmless, immediate medical attention is needed if you notice:

• Sudden increase in floaters
• Flashes of light
• Curtain-like shadow in vision
• Loss of side vision

These symptoms may indicate a retinal tear or retinal detachment, which requires urgent treatment.

Diagnosis & Treatment

An eye specialist performs a detailed retinal examination to identify the cause. Treatment depends on the condition:

• Observation for harmless floaters
• Laser or surgery in severe retinal conditions

Most floaters are part of normal aging, but sudden changes should never be ignored. Early diagnosis can help prevent serious vision loss.
