13 Body Signals Indian Doctors Wish You Wouldn't Ignore

10. Vision changes or sudden visual loss

Blurring, double vision, flashes of light, or sudden loss of vision are all urgent signs. These symptoms can arise from retinal detachment, stroke, optic neuritis, uncontrolled diabetes causing retinopathy, or vascular events of the eye. People with diabetes should have annual eye screenings because diabetic retinopathy can progress without pain until vision is affected. If vision change is sudden or associated with headache, weakness, or numbness, seek emergency care. For gradual changes, book an ophthalmology appointment promptly. Early intervention, including laser treatment for some retinal conditions, is often sight-saving. Wearing readers or changing glasses will not fix warnings of sudden vision loss, so do not delay specialist review.
