Poor overall health of people in Scotland will double the number those who experience sight problems over the next 25 years, an organisation says.
High levels of diabetes, obesity, smoking and poor health can contribute to sight loss, states the Royal National Institute of Blind People (RNIB) Scotland.
It predicts that sight problems will double to 400,000 in the next quarter of a decade.
According to the Scotsman newspaper, Scotland has the second-highest levels of obesity in the developed world and many people smoke.
RNIB Scotland director John Legg said: "We have here a real opportunity to secure world-class services over the next five years.
"International research has shown there is a four-fold return on investment in early eye-care intervention."
Former Public health minister Shona Robison said people did not seem to be aware that unhealthy lifestyles could impact upon their eyesight.
According to the NHS in Greater Glasgow and Clyde, there are 1.1 million smokers in Scotland.
