Your sight test should have been within the last two years, but if your answer is ‘Never’ or ‘What is a sight test?’ — find out why you should get one regularly.
A sight test is part of what happens when you have an ‘eye care appointment’ or an ‘eye test.’
How optometrists conduct sight tests
A complete sight test is done by an optometrist. Optometrists typically work in the consulting room with charts of letters on the wall. They are eye health professionals qualified to carry out sight tests, specific eye health examinations and contact lens fittings. They provide advice and treatment, including prescribing medicines where they have additional qualifications.
When to get your eyes examined
Dr Paramdeep Bilkhu, College of Optometrists Clinical Adviser, explains: “Most people should have their eyes examined at least every two years, depending on their clinical circumstances. It should be as routine as having regular dental check-ups.
“People who have not needed to wear glasses as children often don’t realise that they should see an optometrist regularly, even if they think their sight is fine.”
If your sight test is overdue — or you have never had one — this is the week to change that.
Sight tests assess vision and health
A typical sight test takes around 20–30 minutes. Optometrists check how well you see, including your distance and near vision, to determine whether you need visual correction or whether your current prescription has changed. They also check your eye movements and coordination to make sure both eyes are working together normally.
Importantly, they conduct an eye health examination as part of the sight test. Dr Bilkhu explains: “The eye health examination can identify any issues you may have with the health of your eyes and even potential general health problems that you may be unaware of, such as high blood pressure or diabetes.
“It involves checking the health of both eyes in detail, including examining the outside and inside of them using specialised equipment, such as a slit lamp microscope. Photographs or scans of the back of your eyes might sometimes also be recommended to gain additional information.”
Your and your family’s general eye health is discussed alongside lifestyle, work, hobbies and any eye concerns. This helps the optometrist decide on further tests and how best to manage your needs.
Get regular sight tests
Dr Bilkhu concludes: “Anyone who notices any changes in sight or is having any problems with their eyes should always contact their local optometrist as soon as possible. If your sight test is overdue — or you have never had one — this is the week to change that.”
