SINGAPORE: Wearing contact lenses for prolonged periods can damage the cornea, a transparent layer covering the eye.

Australian researcher Professor Brien Holden was in Singapore on Monday to highlight the problem.

He said the majority of Asians use traditional contact lenses which reduce oxygen flow to the eye. This causes the corneas to age prematurely, resulting in dry or red eyes and blurred vision.

Diabetes can also cause premature corneal ageing.

Professor Holden has had first hand experience. He wore contact lenses for 16 hours every day for 36 years.

Now, he can only wear contact lenses for up to six hours and he has this advice for other users.

Professor Holden, CEO, Institute for Eye Research, Optometry, University of New South Wales, said: “The first thing to do is to consult your local optometrist or ophthalmologist and talk to them about whether you are showing signs of excessive redness of the eye associated with low oxygen of your lenses.

“But by and large, the simplest thing is for everybody to move towards high oxygen permeable contact lenses.” — CNA
