What to do if you notice a change in your sight

It can be tempting to ignore changes in your vision, but it's important to get even seemingly minor issues checked out. By following these steps, you can look after your sight and get the help you need.

Introduction

Our sight will inevitably change as we age. Some changes may be because we need a different glasses prescription, while others may be a sign of an eye condition.

A simple eye examination can pick up the cause of the change, so it's wise to have regular eye check-ups. If you do have an eye condition, it can then be picked up early.

If you notice changes in your vision, book an eye examination as soon as possible. If your optometrist notices any signs of an eye condition, they’ll refer you to someone who can help. This might be an ophthalmologist at the hospital, a specialist optometrist, or your GP.

Signs of changes in your vision

It can be difficult to notice changes in your sight, especially if the changes happen over a long period of time. You might notice changes in your everyday habits, like struggling to see the TV or read your text messages.

Any changes you notice in your vision should be checked. A sudden change will require immediate help, preferably on the same day, while for a more gradual change over weeks or months you should book in a check-up as soon as you can.

When to take urgent action

A sudden change in your vision requires immediate action on the same day. Problems in need of urgent attention include:

• a sudden change in your vision
• loss of all or part of your vision in one or both eyes
• an accident involving your eyes
• suddenly seeing flashing lights or floaters
• double vision which comes on suddenly and is constant
• sudden or constant pain in your eyes
• suddenly becoming very sensitive to light

You can contact your GP or optometrist, or depending on your symptoms you may need to go to A&E.
