Ever wondered why they dim the lights and tell you to raise your window blinds before the plane descends? 

Well it turns out it isn’t just a pointless exercise or something they do to “make the passengers more comfortable”.

Instead it is in case there is an accident that cuts the power and light supply and forces an emergency exit.

It takes less time for your eyes to adjust to the darkness if the lights are already dimmed… and getting in as much natural light as possible also helps. 

Not exactly what you’d want to think about when the plane gets ready to land. 

Pilot Chris Cooke told news.com.au to “imagine being in an unfamiliar bright room filled with obstacles when someone turns off the lights and asks you to exit quickly.”

Perhaps it would have been better to be left in the dark (bad pun) on that one…

We won’t be able to think the same way when the lights are dimmed on future flights, that’s for sure!
