Floaters, flashes and retinal warning signs. This source-reviewed orientation page separates stable record-the-exact-site-side-onset-change-trigger-device-exposure-and-effect-on-function principles from decisions that depend on oral anatomy, periodontal status, visual acuity, pain and photophobia, dilated retinal examination, ocular surface findings, lens type, age, national screening programme, work assessment, surgery stage and direct professional examination.
The named editions, URLs and reuse limits were checked on 2026-09-10. It remains outside search indexes pending a second-person clinical editorial review and localisation.
Start with the description that most closely matches your question about Floaters, flashes and retinal warning signs. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
These concise notes are independently written from the source set below. In an emergency, use the local emergency number and follow the dispatcher rather than relying on a static page.
Record which eye, exact onset, whether dots, cobwebs or flashes are new or suddenly increasing, and whether there is blur, pain, trauma, recent eye surgery or a dark shadow or curtain. Long-standing stable floaters can differ from a sudden change, but only a proper eye examination can evaluate the vitreous and retina. Looking at a plain wall or comparing photos is not a retinal clearance test.
Sources for this note: Floaters and flashes in the eyes; Uveitis.
NHS guidance advises urgent eye assessment for first or sudden floaters or flashes, a sudden increase, a curtain or shadow, blurred vision, pain, or onset after surgery or injury because a serious retinal problem can threaten sight. Pain, photophobia and marked redness can also point to other urgent eye disease. Do not drive if vision is unsafe; use the local urgent eye or emergency pathway.

This source-review release verifies the named editions, URLs, scope and reuse limits for the orientation page. It remains outside search indexes: it is not an oral or eye diagnosis, retinal exclusion, contact-lens prescription, examination result, child-screening schedule, cataract referral or surgical instruction, and it cannot replace an urgent local eye service, the person’s own dentist, optometrist, ophthalmologist, occupational-health team or treating surgeon.
The following paths are the intentional hand-offs named in the brief. They keep adjacent subjects separate while making the next useful reference easy to find.
