Quick answer

Distorted vision means straight lines look bent, wavy or smudged, or objects appear the wrong shape. New distortion, especially in one eye or at the centre of vision, can signal macular disease such as wet macular degeneration and should be assessed promptly. Astigmatism and keratoconus are common gradual causes.

## 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.

## 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.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
