The current number plate test in the UK is working well and an adequate means of testing the vision of motorists, according to the transport minister.
Theresa Villers made the comments after a Sheffield MP this week claimed that more tests need to be put in place to ensure that older people who drive have adequate vision.
Ms Villiers noted that existing methods are sufficient and shot down calls for the system to be overhauled.
She explained: "We simply cannot justify the cost that indiscriminate, mandatory eyesight screening would impose on individuals, the government and the devolved administrations."
According to the minister, "little evidence" exists that compulsory formal eyesight tests could have a significant effect on the safety of drivers and pedestrians.
A recent safety warning was issued by car insurance company Swinton, which reminded drivers wearing contact lenses or glasses that they need to check their prescription regularly to ensure they are safe when hitting the road.
