"Myopia can be passed down from parent to child if the condition is congenital. The other factor is caused by the present environment being filled with visual demands," she told the New Straits Times recently.
Dr Haliza, who is also attached to the UKM optometry clinic in Kuala Lumpur, said a study revealed that myopia was not as common among rural children, compared with those living in urban areas.
"Children in rural areas usually spend most of their time outdoors while urban children generally stay indoors watching television or playing video games.
"Maybe, they are not aware of their children's eye condition.
Certain quarters have claimed that LCD televisions were "gentler" to the eyes and the chances of developing visual disorder from watching them was minimal.
"There is no such thing. As long as there is visual demand in places that are not bright enough for the eyes, the risk will always be there."
Dr Haliza advised parents to bring their children for constant eye checks to detect any disorder, so that early treatments could be meted out.
