Optometrists say people ignore advice and chose to drive daily
It comes after calls for serious changes to be made following the landmark inquests into the deaths of four people in Lancashire by people who shouldn't have been driving
Older motorists could be required to pass eye tests to keep their driving licence.
Optometrists say people ignore their advice and continue to drive despite their eyesight every day.
It comes as the government say they're open to change - after a landmark inquest into the deaths of four people in Lancashire - all caused by people who shouldn't have been behind the wheel.
Chief Executive of the Association of Optometrists Adam Sampson says his members often find themselves unable to do much to stop people driving: "Every day, some of them will be seeing people who cannot see to the standards that is required. They're nevertheless walking out, getting in their cars and driving away, and that there's very little that they can do about that to protect the public.
"Over half our members say that they will probably once a month, have somebody sitting in their chair who are not of the right legal standard and they will then strongly believe that person is a driver and many of those people will continue to drive."
Adam Sampson adds that he feels the current system is too fragmented and hopes all parties involved are included in finding a solution: "We also need proper IT connectivity between high street optometry and people like the DVLA so that we can automatically press a button and supply the evidence if that's what's required.
"We need to make sure that everybody is in that conversation."

Transport Secretary Heidi Alexander told the Commons Transport Select Committee that is something she is "open to considering" as part of the Government's forthcoming road safety strategy.
Earlier this month she received a prevention of future deaths report from HM Senior Coroner for Lancashire Dr James Adeley, which related to the deaths of four people killed by drivers with failing eyesight.
Ms Alexander said: "I know that reading that report will be very distressing for the families of the victims who were killed.
"That, of course, was a situation where the optician had suggested to (four) individuals that they needed to advise the authorities that they had a medical condition which affected their eyesight and where they shouldn't be driving.
"And of course, that didn't happen. So I am open to considering the evidence on this issue."
Dr Adeley described the UK's licensing system as "the laxest in Europe".
Drivers are not subjected to mandatory checks of their skills or health once they obtain their licence, no matter how old they become, although they are required to inform the Driver and Vehicle Licensing Agency (DVLA) if they are no longer fit to drive.
Dr Adeley wrote: "Self-reporting of visual conditions permits drivers to lie about their current driving status to those performing an ophthalmic assessment and avoid warnings not to drive.
"Drivers may also admit they drive but then ignore instructions not to drive and fail to notify the DVLA."
He made the remarks at the inquests in Preston of Marie Cunningham, 79, Grace Foulds, 85, Peter Westwell, 80, and Anne Ferguson, 75.
Asked when the road safety strategy will be released, Ms Alexander replied: "We will be publishing the first new road safety strategy in 10 years, and we hope to publish that document later this year."
