Does the phenomenon of light adaptation occur when driving out of a tunnel?
2 Answers
Yes, at this time, maintain a safe distance from the vehicle in front, reduce the driving speed, and exit the tunnel. More related information is as follows: 1. Introduction to light adaptation: Light adaptation, also known as photopic adaptation, is a type of visual adaptation. Visual adaptation is the process by which the sensation of the visual organs changes with the stimulation of external brightness; sometimes it also refers to the final state achieved by this process. The mechanism of visual adaptation includes the readjustment of photoreceptor cells or neural activity, changes in the pupil, and the transition between photopic and scotopic vision functions. When moving from a dark place to a bright place, especially under strong light, there is an initial moment when the light feels dazzling and glaring, making it almost impossible to see external objects clearly. After a few seconds or minutes, objects gradually become visible. This is called light adaptation. 2. Effects of light adaptation: The phenomenon of decreased sensitivity to light is also known as photopic adaptation.

After a few seconds, objects gradually become visible. This is called light adaptation.
I often drive through long tunnels when leaving the city, and once when exiting a tunnel, I suddenly felt my eyes dazzled by the sunlight, taking several seconds to adjust and see the road clearly. This is the phenomenon of light adaptation, where the eyes need to adjust their visual sensitivity when transitioning from dark to bright light. This situation can be very dangerous while driving, as temporarily not being able to see vehicles or obstacles ahead increases the risk of accidents. It is recommended to slow down before exiting the tunnel and wear sunglasses in advance to mitigate the strong light stimulation, similar to the feeling when walking out of a movie theater into the sunlight. Additionally, keeping car windows clean can also reduce glare, and developing this habit significantly improves driving safety. Always pay attention to your body's reactions, especially when driving in mountainous areas with many tunnels, to avoid fatigue driving that could worsen visual issues.
