Learn about issues of low vision and blindness
The human eye is a sensory organ which is part of the central nervous system.
The human eye plays a key role in our perception of the world, by giving us the ability to visually distiguish form, colour, size, movements, depth and facial expressions.
Low vision or blindness can be present from birth, it can be hereditary and experienced gradually over time, and it can be experienced through illness or injury affecting the brain. We rely on our vision for day-to-day activities. When a change in vision occurs, our independence and mobility can be affected.
Common issues of low vision
We support many different people.
Not every person is completely blind and there are a variety of vision levels and conditions we support.
Some of them include:
- Cataracts.
- Glaucoma.
- Diabetic retinopathy.
- Retinitis pigmentosa.
- Macular degeneration.
- Problems associated with a neurological event such as stroke, trauma or illness.
Eye health and tips
Maintaining good eye health is important in reducing the risk of vision loss in later life.
Regular examinations with an optometrist or ophthalmologist are the best way to promote healthy eyes and prevent a change in vision. Examinations allow for the early detection and treatment of eye disease. 75% of vision loss in Australia is preventable.
If you have a family history of eye disease of are above the age of 40, it is recommended that you visit an eye specialist every two years for review.
Wear safety glasses if you frequently work with tools in a garden or mechanical environment. This will reduce your risk of injury from a foreign body. Many sports such as squash and hockey recommend the use of safety glasses as well. Safety glasses can be fitted with prescription lenses with the help of an optometrist.
Wash your hands regularly and avoid touching your eyes to reduce the chance of eye infection for yourself and others.
We recommend a suitable pair of sunglasses for all outdoor activity to reduce the harmful effects of the sun’s ultraviolet rays. Sunglasses also play a key role in reducing glare.
Where possible, avoid looking at a computer screen all day. Overexposure can lead to dry eyes, headaches and blurred vision. If you work in an environment where long periods of screen time are necessary, take the time to look away at regular intervals.
Additionally, look after your vision by maintaining your general health. Maintain a good diet, avoid smoking, and partake in frequent physical exercise.
