When to worry about eye floaters and flashes of light

Spotting Floaters

Small specks and squiggly lines drifting across your field of vision are known as flashes and floaters, and almost every person has observed them at some point. Dr Minal Kanhere, a consultant ophthalmologist at Dr Agarwals Eye Hospital in Chembur, Mumbai, explains that these are usually caused by small clumps forming in the gel inside the eye as we get older, and they tend to settle down or become less noticeable with time. A few floaters that have been there for months and remain unchanged are generally harmless.

When to See a Doctor

A sudden increase in floaters, a quick change in your vision, flashes of light at the edge of sight, or a shadow creeping in from one side require immediate medical attention. Dr Kanhere notes that these symptoms together can point to the retina pulling away from the back of the eye, which needs to be examined on the same day rather than the same week. People over forty, very short-sighted individuals, and those with a past eye injury or eye surgery face a much higher risk of retinal problems.

Context

An eye check on the same day can prevent permanent vision loss if a retinal detachment is caught early. Knowing the difference between harmless aging changes and sudden new symptoms helps patients seek timely care instead of waiting for the problem to pass on its own.
