It is a common driving hazard in wintertime. The sun comes out suddenly and the wet road surface ahead acts like a mirror, dazzling you with glare and causing temporary blindness.
Our instinctive reaction is to take one hand off the wheel to shield our eyes, or to pull down the car's sun visors.
Glare is experienced when an intensely bright source of light enters your eyes while contrasting with much lower levels of brightness from surrounding areas in your field of vision. In simplified terms, the bright spot throws out your eyes' brightness meter and the resulting glare causes you eye strain, discomfort, fatigue and temporary vision loss.
Most people are highly sensitive to glare, and experiencing it feels uncomfortable. It can also cause a serious safety hazard when you are driving, because you can experience a temporary "road blindness".
