When to get urgent help

  • Sudden new distortion, especially in one eye
  • Distortion at the centre of vision with straight lines looking wavy
  • Distortion with a dark or blank patch in central vision
  • Distortion with eye pain, flashes or many new floaters

Common causes

Distortion happens when the retina or cornea sends a warped image to the brain. These are common causes to read about next.

Macular degeneration Central waviness or smudgy vision, especially in older adults. Keratoconus An irregular cornea causes ghosting, streaks and distorted shapes. Astigmatism Uneven corneal curve distorts vision at all distances. Central serous retinopathy Fluid under the macula can warp central vision in younger adults. Macular hole A defect in the central retina causes distortion and a central blind spot. Epiretinal membrane A scar-like sheet on the macula warps straight lines and central detail. Diabetic macular oedema Macular swelling from diabetes blurs or bends central vision. Diabetic retinopathy Macular swelling from diabetes can distort central vision.

What can help

  • Treat new central distortion as urgent and book an eye assessment promptly
  • Use an Amsler grid at home if advised, to monitor for macular changes
  • Book a routine eye test if distortion has been stable and gradual

Frequently asked questions

What does distorted vision look like?

Straight lines may look wavy or bent, door frames may seem crooked, or faces can look smudged. New central distortion can signal macular disease and needs prompt checking.

Is distorted vision always serious?

Not always. Astigmatism and keratoconus cause gradual distortion. But sudden new distortion, especially at the centre of vision, can be serious and should be assessed quickly.

Can distorted vision be treated?

It depends on the cause. Glasses or contact lenses help astigmatism and keratoconus. Macular conditions may need injections or other specialist treatment, so early assessment matters.
