Eye floaters are small specks or threads that float across your field of vision. They're common and mostly harmless, but a sudden shower of new ones, light flashes, or a dark curtain over your vision means see a doctor today, not next week. Most people spot them when staring at something bright, a clear sky, a white wall, the glare off a window. Tiny dots, squiggly threads, cobweb shapes that drift just outside wherever you're actually trying to look. Chase them with your eyes and they move away. Stop, and they slowly drift back. For most people, that's all it ever is. Annoying, yes. Dangerous, usually not.
Dr. Vaishal Kenia, Chairman and Medical Director at Eye Hospital in Mumbai, says: "Most floaters are benign and don't need treatment. The ones we worry about are the ones that arrive suddenly in large numbers, especially when they come with flashes or any kind of shadow at the edge of vision. Those need to be checked the same day."
What Causes Eye Floaters and Are They Dangerous?
Inside the eye is a clear gel called vitreous humor. It fills most of the eyeball and keeps its shape. Over time, this gel slowly breaks down. Tiny fibres inside it clump together, and those clumps cast shadows on the retina. That shadow is what you see as a floater. It shifts when you move your eyes because the gel moves with them.
Here's what commonly brings them on:
Natural Ageing: The vitreous shrinks and liquefies gradually after 40. Floaters that appear slowly over years are almost always part of this process. Common, expected, and not dangerous on their own.
High Myopia: People with significant minus power have a larger eyeball with a thinner, more stretched retina. The vitreous changes happen earlier and more frequently in myopic eyes, which is why floaters tend to show up younger in this group.
Posterior Vitreous Detachment: As the vitreous shrinks, it eventually pulls away from the retina entirely. This is called PVD and it's the single most common trigger for a sudden new batch of floaters in adults over 50. Usually harmless, but it needs a retinal check to rule out a tear.
Retinal Tear or Detachment: This is where floaters stop being benign. If the vitreous pulls hard enough when separating, it can tear the retina. A tear left untreated can lead to detachment. Sudden floaters with flashes of light is the combination that needs same-day attention.
For a thorough retinal evaluation, the retina clinic at Kenia Eye Hospital handles flashes, floaters, and urgent vision changes with prompt assessment.
Warning Signs You Should Never Ignore
Floaters that have been around for years and haven't changed are generally fine to monitor. The ones that need urgent attention behave differently. Here's what to watch for:
Sudden Flood of New Floaters: A gradual increase over months is one thing. Dozens appearing at once, especially a dark cloud or shower of dots, is the vitreous signalling something acute. Don't wait to see if it settles.
Flashes of Light: Brief streaks in peripheral vision mean the vitreous is physically pulling on the retina. The retina has no pain receptors, so flashes are how it signals that something is wrong. Flashes alone, even without floaters, need a check.
A Shadow or Curtain Over Vision: A dark area creeping in from one side is a retinal detachment until proven otherwise. This is a same-day emergency, not a next-week appointment.
Sudden Drop in Vision: If floaters arrive alongside a rapid loss of central or side vision, something is acutely affecting the retina or vitreous. Immediate assessment is needed.
