Common causes

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

Age-related macular degenerationCentral waviness or smudgy vision, especially in older adults.KeratoconusAn irregular cornea causes ghosting, streaks and distorted shapes.AstigmatismUneven corneal curve distorts vision at all distances.Central serous retinopathyFluid under the macula can warp central vision in younger adults.Macular holeA defect in the central retina causes distortion and a central blind spot.Epiretinal membraneA scar-like sheet on the macula warps straight lines and central detail.Diabetic macular oedemaMacular swelling from diabetes blurs or bends central vision.Diabetic retinopathyMacular 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.
