What happens during the test
- You'll be asked to read some letters on a chart first.
- Drops are then put in your eyes. These may sting for a few seconds. The drops make your sight blurry after about 15 minutes.
- When the drops start working, you'll be asked to look into a camera. The camera will not touch your eyes.
- Pictures are taken of the back of your eyes. There will be a bright flash when a picture is taken.
Your appointment will usually last about 30 minutes.

For up to 6 hours after the test:
- your sight may be blurry – do not drive until it goes back to normal
- everything can look very bright – wearing sunglasses can help
You will not get your test result on the day.
You'll get a letter about your result within 6 weeks.
