Poor eyesight an indication of poor health

POOR eyesight could be linked to higher death rates, says a new study.
Reflecting a trend in Australia, Britain and the United States, a new study among Chinese in Singapore's Tanjong Pagar district has shown that those with poor vision are about three times more likely to die than those with good eyesight.

The study, conducted over a seven-year period, found that mortality rates were higher regardless of other underlying health conditions. It tracked Singaporeans aged 30 to 79 years from 1996.

Associate Director Wong Tien Yin of the Singapore Eye Research Institute, at the Singapore National Eye Centre, who spearheaded the the study, said the findings showed that poor eyesight was not to be taken in isolation.

'People tend to underestimate the impact of visual impairment, but this shows it's a marker for poorer overall health, and isn't just for ophthalmologists to be concerned about,' said Dr Wong.

Previous studies on visual acuity and its link to mortality have been carried out in the United States, Australia and the United Kingdom. Although the link was noted in all countries, the correlation was strongest in Singapore.
