Flight attendant shares how passengers are used to ensure safety without realizing it

According to Aero Corner, opening the shades helps the eyes adapt to the lighting conditions outside.

In an emergency, where passengers may need to evacuate the plane quickly, it is much safer if their eyes have already adjusted to the outside lighting.

Without this integral step, they may not be fully aware of their surroundings.

But while passengers are extremely helpful in the rare event of an emergency during takeoff or landing, their number one priority can still be to relax and enjoy the flight.
