Eye examinations

Most people should have their eyes tested at least once every two years.

Before your eye examination

Having an eye examination is an important health check for your eyes. Your optometrist will be able to tell you how often you need an eye test. Most people should have an eye examination every two years even if you have no problems with your vision.

During your eye examination

An eye examination with an optometrist is very straightforward. Your eye examination will probably last somewhere between 20 to 30 minutes.

After your eye examination

Your optometrist will always discuss the results of your eye examination with you. You may find it helpful to make notes or to ask the optometrist to write down key points, so that you may refer to them later.

Having an eye examination at home

If you or someone you care for are unable to leave home due to a physical or mental disability or illness, you could be eligible for an eye examination at home at least every two years, and more frequently if advised to do so by an optometrist or doctor.
