Refractive errors are when the image of what you are looking at is not focussed properly onto the retina. The retina is like a film in a camera. There are four major refractive errors: myopia, hyperopia, presbyopia and astigmatism. For perfectly clear vision, the image of a viewed object needs to be focussed onto the retina, just as a camera has to be focussed properly in order to take a clear picture. If the image is not focussed exactly on the retina, then the image will be blurred, just like an out-of-focus photograph. In this case, the person is said to have a refractive error.

Eye diseases are relatively rare, although they become more common as we get older. All eye diseases should be regarded as serious - even diseases that appear mild have the potential to cause serious damage if not treated appropriately. Many serious eye diseases do not have dramatic symptoms. Some people with serious eye diseases don't realise there is a problem until they've suffered irreversible damage. Everyone should have a checkup from an optometrist or ophthalmologist every two years. Your optometrist may recommend more frequent checks if you're at higher risk. More information.
Sixty per cent of all eye injuries happen at work making it imperative for employers and employees to reduce the risk of eye accidents. Most eye injuries can be prevented making sure you have appropriate prescription and non-prescription eyewear for the work you're doing. Optometrists around Australia are conducting vision screenings with local businesses as part of Optometry Australia's and HOYA Lens Australia's Workplace Eye Safety campaign. Optometrists can offer eye health and vision screenings, professional consultation, and individually tailored programs for local businesses to help keep employees safe from eye injuries.

You may be aware of the dangers of UV exposure to your skin, but are you aware that your eyes are vulnerable to UV damage anytime of the day, anytime of the year?
Almost 60 per cent of Australians believe it is only the midday sun that poses the greatest UV threat but this not the case. UV exposure to the eye before 10 am and after 2 pm may be higher than during the middle of the day on some days due to the angle of the sun in relation to the eye. More information.
Vision and ageing
From 40 onwards, it is normal to experience changes in your vision. You are also at much higher risk of certain eye conditions. While many of these changes or conditions can be easily treated, often you won’t know if you have a serious eye condition, and if left untreated can lead to permanent vision loss. More information.
Good nutrition is good for eye and general health. A balanced diet including fruits, vegetables, nuts, and fish provides essential antioxidants that support good eye function.
A variety of foods contain antioxidants which can help you maintain your eye health. Nutritional supplements that support an inadequate diet should only be taken in consultation with your optometrist or other qualified health professional. More information.
