At night, visual acuity...
Human factor: Physical factors
Explanation
Driving at night presents several challenges that affect **visual acuity** and, therefore, driving safety.
- **Reduced lighting:** At night, roads are less illuminated, making it difficult to clearly see distances, people, objects, and other vehicles. This means our ability to perceive visual details is reduced.
- **Glare:** The headlights of other vehicles can cause glare, introducing too much light into our eyes and further impairing vision. This can make it difficult to see the road and obstacles clearly.
- **Adaptation to light changes:** When moving from well-lit areas to those with low light, our eyes need time to adapt, which temporarily reduces our visual capacity.
For these reasons, **visual acuity is reduced** when driving at night, making it necessary to take additional precautions, such as reducing speed and avoiding glare.
