"Impaired vision can be casued by a range of conditions including diabetic eye disease and cataracts," Dr Razavi said.
"In fact cataract surgery is the most common operation in the world.
"With the latest technology, it is a safe and painless operation and lead to improvement of vision for people."
However, Dr Razavi said maintaining good eye health can help reduce your risk of developing eye diseases and potentially avoid surgery.
Good eye health top tips
1. If you're diabetic or pre-diabetic speak with your GP or other health care providers to ensure your blood sugar and blood pressure is under control. Lowering blood sugars and blood pressure leads to a slowing down of diabetic eye disease which is the leading cause of poor vision for people of working age (40 to 60 year olds) in Australia.
2. Don't smoke or try to quit smoking if you do. As well as affecting your heart and brain health, smoking increases the risk of some eye diseases. The main one is age-related macular degeneration (AMD), which is the leading cause of blindness in Australia and is made worse if you smoke.
3. Have your eyes checked by your local optometrist at least once every two years. This is a good way of checking your glasses prescription as well as your general eye health. Some eye diseases, such as glaucoma, are silent and don't cause any symptoms in the early stages. By seeing an optometrist, glaucoma and other conditions can be picked up early, and you can be referred for treatment before they cause permanent loss of vision.
