§ Baroness Gardner of Parkesasked Her Majesty's Government:
What research there has been on the correlation between eyesight standards and road accidents.
§ The Parliamentary Under-Secretary of State, Department of Transport (Lord Brabazon of Tara)I have placed two key research documents from the Transport and Road Research Laboratory in the Library of the House:A Reanalysis of California Driver Vision Data and A Survey of Visual Acuity of Drivers. I have also placed a copy of a paper entitled Vision and Driving prepared by the Department's Medical Adviser.
These documents show clearly that defective eyesight is not a significant factor in road accidents for the general driving population as a whole.
