Although we rely on our vision for many areas of our life, good visual acuity is essential for driving. In fact, it is so important that the driver’s visual capabilities are assessed before they can achieve their driver’s license and might be checked again at license renewals depending on individual state regulations. Nevertheless, it isn’t just our visual acuity that factors into how well we can see when we drive. The weather plays a huge role in determining driving conditions, and bright sunshine can be just as hazardous as heavy rain or ice. The reason for this is something called glare. Fortunately, this can be resolved with a very simple solution – wearing sunglasses.
