Warning signs

How AMD announces itself

Early AMD is silent. As it progresses, the centre of vision starts to play tricks: lines bend, faces blur, a quiet grey patch appears. Check each eye separately — one eye often covers for the other.

Signs to watch for

  • Straight lines look wavy. Door frames, tiles or window blinds appear bent or rippled — the most classic early warning sign.

  • A dark or empty spot. A grey, dark or blank patch sits in the middle of what you see and grows over time.

  • Faded colours. Colours lose their vividness, or things seem washed out.

  • Trouble with faces and text. Recognising faces gets harder; print looks blurry even with reading glasses.

  • More light needed. Reading or close work demands brighter and brighter light.

  • Slow adjustment. Moving from bright to dim environments, one eye takes noticeably longer to adapt.

Self-check

The Amsler grid

Eye doctors use this grid to spot macular problems. Try the simulation below to see what AMD can make it look like.

At home: wear your reading glasses, cover one eye, focus on the centre dot at normal reading distance. If lines look wavy, broken or a patch is missing — see an eye doctor promptly.

See an eye doctor within days if:

  • Straight lines suddenly look wavy or bent
  • A dark or grey spot appears in the centre of one eye
  • Things suddenly look a different size in each eye

These can signal wet AMD. Treatment works best within days — delay can cost sight permanently.

Have an eye exam every year if you:

  • Are over 50
  • Smoke or used to smoke
  • Have AMD in your family
  • Have noticed any change in your vision

Early AMD has no symptoms at all — only a retinal exam can find it. Ask about AI-based retinal photo screening at your next visit.
