Vision at night Amazingly, 20% of drivers can’t see properly at night. If you think you may have a problem in this area, ask your optician for advice. The following tips will also be useful: If you wear glasses, make sure your lenses are clean before you begin your journey Don’t wear sunglasses or polarising lenses in low visibility or at night An anti-reflection coating will reduce headlight reflections and give you clearer vision in poor light conditions Never wear yellow tinted glasses at night – they darken shadows and can make it difficult to see cyclists and pedestrians Make sure your headlights are clean, at full strength and adjusted so they don’t cause glare to other road users.
