When should sunglasses be worn while driving?

Wearing sunglasses while driving is primarily beneficial during sunny conditions when bright light can impair your vision. By wearing sunglasses on sunny days, you reduce glare and improve your ability to see clearly. This is crucial for maintaining focus on the road and other vehicles, thus enhancing safety.

Driving at night or in poor visibility conditions, however, typically does not require sunglasses. In fact, wearing sunglasses in low-light situations can hinder visibility, making it more difficult to see the road or other drivers.

While some drivers may choose to wear sunglasses for long distances to reduce fatigue, this isn't a general rule, as it relies more on individual preference and lighting conditions. Lastly, it’s not advisable to wear sunglasses in all weather conditions because they can reduce visibility during cloudy or overcast days, where better clarity would allow for safer driving.

In summary, wearing sunglasses is most appropriate during bright, sunny conditions to combat glare and enhance visibility, directly helping with safe driving practices.
