Mine had settled over the past year which was fine for them.
And no chance of getting a tube mate, I had to wait 30 mins for Mum to finish swanning around Lakeside at her leisure despite her having my sunglasses which under the flourescent lights I would have appreciated a lot!
I found walking back to the car I could just keep one eye open but as soon as we got to the underground carpark where it was dark I could open my other eye again, when we started driving eyes shut all the way home, it was just too bright. Soon as I got indoors, I went to a room with the curtains shut and lights off and felt much better, lied down for a few hours and after that I was fine
Basically don't let Mum carry your sunglasses and get home and into a dark room asap for a few hours and you'll be fine
