What is vision screening?
Vision screening is a series of tests conducted by a medical expert in eye health. The tests are used to help determine a problem a patient may have with their eyes, the lens or other functions like the optic nerve.
The test measures the eyes ability to function and potentially detects other underlying illnesses like glaucoma, or even illnesses in other areas of the body that the patient may not know about.
Once a problem is diagnosed, a patient can then be treated with the right medication, be prescribed the correct glasses or contact lenses or undergo surgery.
Regular vision screening at any age is an important part of looking after yourself. It is recommended to have an eye test every two years as an adult, though it is advised children to be monitored every year.
