How often should you have an eye test?
The usual advice is every two years. That is a good place to start, but it is not right for everyone, and we are often asked who should come more often.
The two-year rule
For most adults with no eye problems, an eye test every two years is the guide. It is long enough to catch gradual changes in your vision, and often to find the first signs of eye conditions that cause no symptoms. Glaucoma, for example, can develop without you noticing anything for a long time.
When to come more often
Your optometrist may suggest a test every year, or sooner, if you:
- are over 70
- have diabetes
- have a family history of glaucoma or another eye condition
- wear contact lenses (an annual check is a condition of supplying them)
- have a high prescription or have had a change recently
- take medicines that can affect your eyes, which your doctor or pharmacist can tell you about
Children's eyes change faster. Read our post on children's eye tests before school.
Between tests
Do not wait for your next appointment if something changes. Book promptly if you notice:
- blurred or double vision that is new
- flashes of light or a shower of new floaters
- eye pain or redness that does not settle
- a shadow or curtain across your vision
If you have a sudden loss of vision, or a sudden shower of floaters with a shadow, call us or go to A&E straight away rather than waiting for an appointment.
Free or paid
Many people qualify for an NHS-funded test: see who qualifies. If you do not, a private eye test is £25 and includes a digital retinal scan.
A habit worth having
A test is not only about glasses. Your optometrist looks at the health of your eyes and, sometimes, finds signs of general health conditions such as high blood pressure. Choosing a time of year to book, such as your birthday, makes it easy to remember.
