To maintain good eye health and vision, it is important to have your eyes tested every two years, or more frequently if advised. You should seek advice immediately if you have any sudden loss of vision, eye pain, inflammation or irritation. Most eye diseases can be found during a routine eye test and treated when detected at an early stage. If you have health problems, such as diabetes, you may need to visit your optometrist more frequently to detect any complications.

What does it mean to have 6/6 vision?

6/6 (20/20) vision is your visual acuity, or the sharpness of vision at six metres from an object. Having 6/24 vision means you can see at six metres what a person with normal vision can see at 24 metres away. 6/6 does not translate into perfect vision and does not indicate other important aspects of sight such as peripheral vision, the ability to identify colours or depth perception.
