When to see a doctor
See a doctor urgently if:
- If you notice sudden changes in your vision, see an eye specialist the same day or within a day or two.
- The emergency symptoms listed above need an immediate call to your local emergency number.
Book a routine appointment if:
- Have a full sight test every two years, or as often as your eye care professional advises.
- Children should have their eyes tested from a young age, and again at key school stages.
Diagnosis
An eye care professional will ask about your medical history and any changes you have noticed. They will then look at the front and back of your eyes using special lights and lenses. Ask them to explain what they are doing and what they are looking for.
Tests that may be done
- Reading letters on a chart (this checks sharpness of vision)
- A puff of air or contact with a smooth probe to check eye pressure
- Drops that widen (dilate) your pupil so the back of the eye can be seen
- Tests to see how both eyes work together when looking at a target
What to expect at your appointment
Most eye tests are painless and take about 20–30 minutes. Some drops may make your vision blurry and your eyes sensitive to light for a few hours, so ask whether you should bring a driver or sunglasses.
Treatment
Treatment depends on what is causing your symptoms. For many people, glasses or contact lenses are enough. For others, eye drops or a procedure may be recommended. Your eye care professional will talk through the options and help you decide what fits your lifestyle.
Self-care at home
- Take regular breaks from screens using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
- Use good lighting when reading or working.
- Wear sunglasses on bright days to protect your eyes from UV light.
- Keep your glasses or contact lenses clean and use them as directed.
Medical treatments
Depending on the cause, your eye care professional may suggest prescription glasses or contact lenses, lubricating eye drops, or a procedure to improve your vision. They will explain how the treatment works, how often to use it, and any possible side effects. Always ask how you should use any treatment before leaving the clinic.
When is surgery considered?
Surgery may be offered for some eye problems, such as cataracts, or for vision correction such as laser eye surgery. Ask about the recovery time, what you can expect afterwards, and what questions you should ask before agreeing to a procedure.
Living with this condition
After a sight test or treatment, you may need time to adjust. Ask when you can drive, read, or go back to work. Keep the aftercare instructions you are given, and contact the clinic if anything does not feel right.
Lifestyle tips
- Keep a note of your most recent eye test results.
- Use the glasses or contact lenses your eye care professional recommends.
- Wear eye protection for DIY, sports, or any activity that could cause eye injury.
- Book your next check-up before you leave the clinic.
Diet and exercise
Eat a balanced diet with plenty of vegetables, fruit, and foods rich in omega-3, such as fish. Regular physical activity helps circulation and overall health, which is also good for your eyes.
Mental health and emotional wellbeing
It is normal to feel anxious if your vision changes. Talk to your eye care team about your concerns. If you feel very low or are finding it hard to cope, contact your local mental health crisis service.
Prevention
Not every eye condition can be prevented, but regular eye exams and healthy habits can help stop some problems from getting worse and can protect your sight for longer.
Vaccines
Some infections can affect sight. Speak to your doctor about recommended vaccinations, especially if you have a long-term condition.
Screening programmes
Regular sight tests are a simple form of screening. The NHS recommends a full test every two years, and more often if you have diabetes or another condition that raises your risk.
Complications
If left untreated
- Some eye conditions can silently impair sight if left untreated, such as increased pressure in the eye.
- A delay in treating a sudden change in vision can make recovery harder.
- Failing to correct simple problems like blurred vision may cause headaches and increase the risk of falls.
Long-term outlook
The outlook for most vision problems is very good when they are caught early. Many conditions can be managed successfully with glasses, contact lenses, drops, or simple procedures. Your eye care team will work with you to protect your vision and answer your questions every step of the way.
