The majority of employers are concerned that some of their employees are driving for work with dangerously poor eyesight.

This is despite the fact that 84% of employers say it as ‘very important’ that employees for work have their eyes tested regularly.

However, 60% said they do not have a policy to test the eyesight of employees who drive for work.

Of those who do have a policy, only 13% do so on an annual basis.

And only 16% do so every other year.

In addition, 15% will only check employees’ eyesight when requested.

Most employers feel it should be employees’ responsibility to ensure their eyesight is sufficient for driving.

"There seems to be a discrepancy between what employers and fleet managers think should be the case and what actually happens in the workplace,” Laura Butler, corporate account manager for Specsavers Corporate Eyecare, which carried out the research, said.

“Our research shows nearly all employers - 90% - believe legislation should be in place to ensure employees who drive during the course of their work have their eyes tested regularly.

"Very few, however, have actually put this in place themselves.

"It is interesting that 60% of employers have had their own eyesight tested within the last 12 months but only 13% have a policy to do the same for their staff.”
