Visual Conditions<\/b><\/span><\/h2>\n

Refractive errors are the most common type of vision problem. These occur when the shape of your eye stops light from focusing correctly on your retina (the light-sensitive layer at the back of the eye). <\/span>Myopia, hyperopia, astigmatism and presbyopia are all refractive errors. The prevalence of both myopia and hyperopia is increasing.<\/span><\/p>\n

Some other visual conditions include low vision, colour vision deficiency, binocular vision problems and accommodation (the natural focusing ability of the eye), all of which may impact on a person’s daily living tasks.<\/p>\n

It can occur on its own, or in combination with hyperopia or myopia. Astigmatism occurs when your cornea is shaped more like a rugby ball than a soccer ball. This results in the light entering the eye focusing at two different places on the retina and leads to blurred vision.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Colour vision deficiency (colour blindness)” tab_id=”1620391486166-dcb63759-316d”][vc_column_text]<\/p>\n

People who have a colour vision deficiency have difficulty seeing colours \u2013 usually red-green. It is usually inherited and affects more boys than girls. The deficiency is thought to be caused by genetic changes that prevent colour-sensitive cells (cones) located in the back of the eye from functioning normally.<\/span><\/p>\n

Colour vision deficiency is often picked up by parents if their child has difficulty recognising and identifying different colours or an inability to separate things by their colour.<\/span><\/p>\n

[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Hyperopia (long-sightedness)” tab_id=”1620391535619-8563efe6-a410″][vc_column_text]Hyperopia is the most common eye condition in Australia. If you are long-sighted, you can see distant objects well, but have trouble focusing clearly on things up close, such as reading or looking at computer screens. Hyperopia is usually present at birth and, if left uncorrected, can cause symptoms such as eyestrain, headaches and end-of-day tiredness.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Low Vision” tab_id=”1620391889063-8b431eb3-c841″][vc_column_text]Low vision is the term used to describe significant and permanent visual impairment that cannot be corrected fully with optical aids, medication or surgery. Low vision can affect people of all ages and have an impact on many aspects of a person\u2019s life. It may, for example, cause difficulty in recognising faces, reading the newspaper, seeing the television or computer screen properly, telling colours apart or seeing road signs.<\/p>\n
