Flashes, floaters or a curtain
A sudden shower of spots, light flashes or a fixed shadow can occur with a retinal tear, bleeding or detachment and needs urgent retina examination.
Sudden blurred vision doctor in Bhopal
Prompt assessment can distinguish a glasses or surface problem from retinal, optic-nerve, pressure-related or neurological conditions that need time-sensitive care.
Quick answer
New blur that appears over minutes or hours, affects one eye, persists after blinking, or comes with flashes, many new floaters, a curtain or shadow, eye pain, redness, halos, injury or recent eye surgery needs urgent assessment. Record when it began and whether it affects one eye or both.
Urgency guide
This guide cannot diagnose the cause, but it can help you communicate important details when you call.
A sudden shower of spots, light flashes or a fixed shadow can occur with a retinal tear, bleeding or detachment and needs urgent retina examination.
Severe pain, redness, halos, headache, nausea or vomiting needs immediate evaluation for acute pressure or corneal problems.
Marked painless loss in one eye can be caused by retinal or vascular disease and should be treated as an emergency.
Eye trauma, a foreign body or chemical splash needs prompt care. Begin clean-water irrigation immediately after chemical exposure and seek emergency help.
New pain, redness or reduced vision after an eye procedure needs urgent contact with the treating team.
These conditions increase the range of possible retinal and vascular causes, so do not assume the change is only a glasses-number fluctuation.
At the eye examination
The doctor will ask exactly when symptoms started, whether one or both eyes are affected, and whether pain, headache, flashes, floaters or neurological symptoms are present.
Do not drive if vision is significantly reduced. Bring medication details and previous eye records. If stroke symptoms are present, go directly to emergency medical care.

Read profileSudden vision FAQs
Not every episode has a dangerous cause, but sudden, persistent or marked blur cannot be safely classified without assessment. One-eye loss, neurological symptoms, pain, flashes or a shadow increase urgency.
That pattern can occur with an unstable tear film, but repeated or new symptoms still deserve an eye examination, especially if one eye is consistently worse.
Changes in blood glucose can alter focus, and diabetes can also damage the retina. An examination is needed to tell these apart.
Do not wait for clinic hours if there is severe loss, stroke symptoms, a painful red eye, injury, chemical exposure, a curtain-like shadow or sudden flashes and many floaters. Seek emergency care.
