HUDDERSFIELD road safety charity Brake is backing a campaign by supermarket chain Asda for more drivers to have eye tests.
Asda Motor Insurance - a branch of the chain - has launched a `safe sight' campaign.
At its Vision Stores, from today, Asda will be offering a free, two-minute vision `MOT' to see if drivers can read a number plate from 20 metres (60ft) away and that their eyesight is up to scratch.
The nearest Vision Store to Huddersfield is in Dewsbury.
David Rutley, Asda's director of financial services, said the campaign would reduce the number of drivers on UK roads who cannot see properly.
About 320,000 accidents a year were caused by drivers with poor eyesight.
And one in 10 drivers had never had their eyes tested.
Mr Rutley added: "More 20/20 vision on our roads means fewer accidents and fewer insurance claims, helping to keep insurance costs low."
Mary Williams, chief executive of Brake, said: "No-one would dream of operating heavy machinery if their eyesight was impaired, yet thousands of drivers get behind the wheel, even though their vision is poor.
"Brake urges all drivers to get their eyes tested, today. It could literally save your life and the life of another."
As well as the two-minute eye `MOT', Asda Vision Stores also offer full eye tests.
