Question to the Department for Transport:

To ask the Secretary of State for Transport, what research has been commissioned by his Department into the number of traffic accidents in which a driver's defective eyesight was a contributory factor; and whether an estimate has been made of how many such accidents were fatal.

The number of reported personal injury road accidents in Great Britain in which the contributory factor “Uncorrected, defective eyesight” was reported can be found in statistical table ras50001. This factor is reported when the driver or rider's poor vision helped bring about the accident. It includes cases when the driver/rider was not wearing glasses when they should, or wearing the wrong glasses.
