Good vision is critical for all drivers. Drivers are legally required to be able to read a number plate from a distance of 20.5 metres and to wear their corrective prescription eyewear at all times. Insurance will be invalid if they can’t meet this standard.
Drivers should always wear their glasses or contact lenses if they need them for driving. If they don’t, they are breaking the law and putting others at risk.
Good tips that can help drivers include polarizing lenses that reduce glare, making them ideal for driving during bright daylight hours and anti-reflection coating that reduces headlight reflections and provides clearer vision in poor light conditions.
Drivers need to seek professional advice rather than rely on their own judgement as to how good their eyesight is.
