You are right. it is for night adaptation of our eyes. For the pilots they keep their cockpit lights dim anyway during whole flight except when flying around thunderstorms.(there they keep the lights bright so that in case of a lightning blinding them temporarily, they can see the instruments quickly if it is brightly lit as compared to if it was dim)
But, gaurav's question is about cabin lights in the passenger section which in no way affect the PILOT's eyes.
Here the reason is for the night adaptation of
passenger's eyes only in the unlikely event of a rejected takeoff/passenger evacuation or forced landing or ditching etc etc. We donot want the passengers to come out from the
brightly lit passenger cabin to darkness outside when the passengers eyes will take long time before acclamatising themselves to the dim light outside. Precious moments might be lost in a passenger taking the right path through the ground around to a safe area /see the life rafts etc etc.
So Lights in the passenger cabin are dimmed during the takeoff and landing as a rule. Dont worry about the pilots. They will keep it a dim lit cockpit anyway ;-)
Generally cabin lights control is with the Inflight Supervisor at the back only and not from the cockpit.
