168. Visual impairment

Visual impairment is a reduction in vision that can affect a person’s ability to see clearly, judge distances, detect movement or recognise hazards. It can involve reduced visual acuity, a restricted field of vision, poor contrast sensitivity, double vision or difficulty seeing in low light. Because safe driving depends heavily on vision, drivers must meet the minimum eyesight standards required in their country and use glasses, contact lenses or other approved visual aids when necessary.

How can visual impairment affect driving?

Visual impairment can make it harder to recognise signs, detect pedestrians and vehicles, judge distance and speed or see hazards in time.

What aspects of vision are important for driving?

Important visual functions include visual acuity, field of vision, contrast sensitivity, depth perception and the ability to see in changing light conditions.

Can you drive if you need glasses or contact lenses?

Yes, provided your corrected vision meets the applicable legal standards. If your licence requires glasses or contact lenses, they must be used while driving.

Can someone with vision in only one eye drive?

In some countries, yes, provided the person meets specific visual-acuity, visual-field and adaptation requirements. The exact rules vary between countries.

Can visual impairment lead to restrictions on a driving licence?

Yes. Depending on the impairment, a licence may include conditions such as mandatory glasses, daytime-only driving, geographic restrictions or other limitations.

What should you do if your eyesight becomes worse?

If your vision changes significantly or may no longer meet the required standards, seek an eye examination and medical advice before continuing to drive.
