What to do if you notice a change in your vision

It's easy to brush off small changes in your vision, but even minor issues are worth checking. Taking the right steps now can help you protect your sight and ensure you get the right support.

Introduction

Our vision naturally changes as we get older. Sometimes this simply means you need an updated glasses prescription, but changes can also be an early sign of an eye condition.

A routine eye examination can identify the cause, which is why regular check-ups are so important. Detecting any problems early gives you the best chance of managing them effectively.

If you notice any changes in your sight, book an eye examination as soon as possible. If your optometrist spots signs of an eye condition, they'll refer you to the most appropriate professional for further care, such as a hospital ophthalmologist, a specialist optometrist, or your GP.

Spotting changes in your vision

Changes in your sight can easy to miss, particularly when they develop gradually over time. You might first notice them through everyday difficulties, such as finding it harder to read text messages or see the television clearly. 

Any changes in your vision should be checked. Sudden changes need urgent attention - ideally on the same day - while more gradual changes over weeks or months should be assessed at an eye examination as soon as possible. 

When to take urgent action

A sudden change in your vision needs immediate attention, ideally on the same day. Seek urgent help if you experience any of the following:

• a sudden change in your vision
• loss of all or part of your vision in one or both eyes
• an injury or accident involving your eyes
• sudden flashes of light or an increase in floaters
• double vision that starts suddenly and doesn't go away
• sudden or persistent pain in your eyes
• sudden sensitivity to light

You can contact your GP or optometrist. Depending on your symptoms, you may need to go to A&E for urgent assessment.
